    Almost everything you wanted to know about the Lilliput 669GL

    There has been a lot of confusion around the various models of the 669, as there at least 7 different versions being sold. In fact, Lilliput has made it so confusing that they actually send us the wrong version of the 5 wire 669, and it took us a week to figure it out and Lilliput had to search by the serial #’s to confirm that for us. After speaking to the fourth person in two weeks that got ripped off buying a 669 I decided that it was time to write this. The various versions of the 669 include:
    669GL-70NP/C
    669GL-70NP/C/HB
    669GL-70NP/C/T
    669GL-70NP/C/T/AS
    669GL-70NP/C/T/HB
    669GL-70NP/C/T/HB/AS
    669GL-70NP/C/T/5HB

    The 669GL-70NP/C and 669GL-70NP/C/HB are actually not touch screen monitors. They are the two non touch versions of the 669 that are aimed at the photography market for connection to SLR cameras. You can tell they are non touch screen versions by looking at the exact part #. You will notice that they are missing the “T”. A “T” in the part # stands for touch screen. Normally these two versions of the 669 are priced lower than their touch counterparts but it is still an easy mistake to make when not paying attention or buying from a shady seller. If the monitor you are looking at appears to be way cheaper than it should be pay attention to the exact part #. The 669GL-70NP/C uses a 250 nit Innolux AT070TN82 v.1 (referred to as TN82 v.1 moving forward) with 500:1 contrast ratio and 60 pin ttl connector. The 669GL-70NP/C/HB uses an Innolux AT070TN84 v.1 (referred to as TN84 v.1 moving forward) LCD panel that is 450 nits with a 500:1 contrast ratio and a 60 pin ttl connector. A picture showing the different ttl connectors can be seen here.

    On to the 669GL-NP/C/T, the no frills version of the 669 with a touch screen. This model can be extremely confusing especially from a replacement part perspective. On product launch this model was using the TN82 v.1 250 nit LCD panel. After a few months we noticed that Lilliput had changed ttl connector to a 50 pin connector and started to use the 300 nit Innolux AT070TN83 v.1 LCD panel. It should be noted that this is the same LCD panel that is used in the US version of the EBY701 (yes there is a difference between the EBY701 depending on what market it is made for, but I will save that for another post)as well as the 629GL and the DVI version of the 629. Other then the change to the TTL connector the control board was basically the same. If you have this version of the 669 and need replacement parts you will need to verify which version you have before ordering them. If you have an older 669 (60 pin ttl connector) with a 250 nit panel there is no reason why you cannot upgrade the panel to the 450 nit TN84 v.1 as they are identical except for the brightness. If you have a newer one with a TN83 v.1 panel you can also upgrade to the 450 nit TN84. A picture showing the newer variation of this control board can be seen here.

    The next model is the 669GL-70NP/C/T/AS. The AS at the end of the model # stands for Auto Switching. It is also commonly referred to as the 669GL-70NP/C/T/RCI (for Reverse Camera Input) or the 669GL-70NP/C/T/RV (for Rear Vision). This model is a standard brightness, 250 nit, version of the 669 for use with rearview cameras. It has a green wire coming out of the right side of the monitor. When this wire receives a +12v signal it will automatically toggle the monitor to Aux video input #2 and then back to the original video input (VGA, DVI, HDMI) when the voltage is removed. One easy way to connect this feature for use is to run a wire back to the + lead of your reverse brake light bulb since it only receives power when the car is in reverse. Unlike the standard version of the 669 we have not seen any variation with the type of ttl connector/LCD panel used. This version of the 669 uses the 250 nit TN82 v.1 LCD panel.

    Now I will move on to the high brightness, or 450 nit variations. The 669GL-70NP/C/T/HB/AS is also known as the 669GL-70NP/C/T/RCI or 669GL-70NP/C/T/RV. In this case the addition of the HB to the part # indicates that it is a 450 nit model that uses the TN84 v.1 LCD panel. Just like its 250 nit cousin the addition of the AS, RCI, or RV to the part # means that it has been optimized for use with rear view cameras and will have a green wire on the side. It uses the exact same touch panel (4 wire resistive), control board, and housing as the 250 nit model. The only difference is that they swapped the 250 nit TN82 v.1 out and replaced it with the 450 nit TN84 v.1.

    There is also a 4 wire 450 nit model of the 669 without the auto switching. The model # is 669GL-70NP/C/T/HB. All of the internal components are the same as the auto switching model described above. We do not carry this model so I can’t confirm if the transistors/resistors that enable the auto switching are on the control board or not. I would suspect that they are there and the only thing that needs to be added is a wire to enable the auto switching feature.

    The high brightness models is also where we have seen people getting ripped off, mostly by Chinese sellers on Ebay based out of Hong Kong or Shenzhen. So how do yo know that you have actually received a 450 nit model and not the cheaper 250/300 nit version without opening your monitor up and voiding the warranty? There is an easy way to verify which version you have without even taking the shrink wrap off of the monitor. Every monitor has both a serial # sticker as well as a laser engraving of the serial # on the back of the monitor, like this one, that belongs to a 250 nit 669. The first 3 digits are the model # (669, 629, 869, ect), the second group of digits are a batch # that contain date of manufacture information, and the last 5 #’s are the actual serial # of the monitor. All of the high brightness/450 nit models have a “H” at the beginning of the serial # as shown here. No “H” at the start of the serial # means that it is a 250/300 nit version.

    Last but not least we have the 5 wire variation of the 669. It does come in a standard version without auto switching and the part # is 669GL-70NP/C/T/5HB. I have only seen it for sale on a few odd ball Chinese sites so I will focus on the auto switching version. The model # for it is 669GL-70NP/C/T/5HB/AS. Just like the other versions of the 669 the AS at the end can vary between AS, RCI, or RV. Just like its 4 wire cousin the 5 wire model uses an Innolux TN84 v.1 LCD panel. The control board is the same size as the other models but the layout is slightly different. The standard 4 wire touch panel has been replaced by a 5 wire panel. The change in touch panel means that the 5 wire version will not fit in the Bybyte double DIN frame. If you want a double DIN 669 you have to use a 4 wire version. Just like the 4 wire HB model Lilliput has changed the prefix of the serial # to indicate that it is a 5 wire model. In this case it has been changed to 5H as shown here.

    General information

    Auto Power On
    It has been detailed in another thread but in an effort to consolidate as much information as possible I will cover it again. It is possible to set all versions of the 669 and its 8” brother the 869 to auto power on. The process is the same for all 669/869 models as well as the DVI version of the 629. With the monitor on and connected to a PC so there is an image on the screen press and hold the power button for about 10 seconds, until the hidden menu appears. You have to physically press the power button on the front of the monitor, using the remote control for this step will not work. It is important to remember that if you are putting your 669 into the Bybyte double DIN frame. It is much easier to go through the auto power in process before you start the conversion. Once the hidden menu appears you can use the remote of the buttons on the front of the monitor. You need to hit the menu button two times. On the third screen the first option will say Car Power State and the default value is 0. Use the down arrow to highlight this line and then the right arrow to change the value to 2. Then hit the menu button two more times to exit the hidden menu. The next time you apply power the monitor will come on without pressing the power button. I have noticed occasionally that when hitting the menu button to get to the third page the menu will jump back to the first page. If this happens just hit the menu button until you get to the third screen. I don’t know what causes the menu to do that.

    Drivers
    There always seems to be some confusion about where to download the correct most up to date drivers. The drivers for all 7 and 8” Lilliput monitors can be downloaded HERE.

    Dimensions
    No matter which version of the 669 you have the overall dimensions are identical. They are as follows:
    · Outside dimensions/Plastic housing: 185 x 122 x 32mm W x H x D
    · Active or Viewable area of the LCD panel: 154 x 94mm W x H
    · LCD panel: 165 x 104 x 6mm W x H x D
    *There are 25.4mm to an inch.

    Using the Bybyte double DIN frame
    All non touch and 4 wire versions of the 669 will fit in the Bybyte frame. Neither of the 5 wire models will fit in the frame. Because of the difference in the mounting holes on the control board you need to make sure you get the frame like this one that has the correct “H” bracket for mounting the control board. If you already have the Bybyte frame and you want to upgrade it to a 669 you can purchase just the “H” bracket here and reuse your frame. Also if you want to use the HDMI connection on the 669 along with the Bybyte frame you will need to purchase a HDMI adapter like this one.


    If you have any questions let me know and I will try my best to get them answered for you.

    This is great info. Do you know if the touch screen (the panel with the connector only) are the same across all the different models. I have an older lilliput (not sure if the p/n) and I damaged the touch screen performing the 'lighter trick' to get it to be responsive again. The fix worked but I heated too much and melted/bubbled some of the plastic. The touchscreen connector has 4 pins if it helps, I'd really like to replace it if possible.

    Thanks,

    Lilliput uses the same touch panel for all of the LED backlight 7” monitors (EBY701, 619GL, 629GL, 669GL). The 1 EXCEPTION to that is the 5 wire touch panel on the 669 5HB. It uses a totally different touch panel and connector.

    Just to update anyone else who uses an HDMI connection with the 669GL, there is significant overscan when using the input labeled 'HDMI' on the 669GL, so much so that using Windows is difficult since many clicks need to occur at the edges. There is a simple fix, however, you just need to change the input to 'DVI'. The 'DVI' input does not overscan, and works perfectly fine using the HDMI connectors. For reference, the VGA input 'PC' does not overscan either. I haven't tested the composite video inputs.

    What do the other settings on the hidden menu do? For example, 'Back Car' or 'Logo' or the others?

    Not sure what everything does. I have tried changing some of the settings like back car and have not noticed anything changing. Some of the other settings like Logo appear to be things they can add for OEM customers. Be careful with what you play with. Changing some of the settings will brick the monitor and it will require a firmware reflash.

    will the 669 H-bracket you list on ebay work with the bybyte double-din case as well as the frame?
