But I think a simple capacitor does not blast on a way like that without a good reason...
Hi all,
This site's been a great help to me so far, couldn't have done it without you!
So I was trying to install my carpc into my car yesterday and everything was going well (pictures, etc. to come when it's complete).
But then when trying to wire up my Lilliput it all went wrong.
I'm pretty sure I double checked the polarity of the power before I flicked the switch on the PSU, but something smelt funny. Literally. But it was too late:
(Click on the pictures for a bigger image)
I think it's a blown capacitor (assuming from the markings near it saying C65). Can anyone help me identify what sort of capacitor I need to replace it with?
Thanks in advance.

I have the same problem. If you used a 12v rail off the psu like me, i blew my capacitator and now dont know what to do??
The same problem!
I tried to use power not from in-dash socked but from DC input wire next to RCA cables.
I soldered in the 22mF capacitor but still no picture displayed
So, probably not only one capacitor blows, but something else.

Almost done. Testing...
Are they brand new or refurbished monitors?
I ask, because on the picture linked by Dilmah, the electric components dz1 and d4 on the top are soldered on a quite amateur way...or at least re-soldered once...
In this case try to measure the correct polarity of that capacitor.

OK, try it without backlight. Simple deconnect that unit and investigate, what happens.
If you display a picture with high contrast (eg. white box on black screen) , you can see it w/o backlight, in the case you light directly onto the display with a strong lamp.
That transistor (if it is a transistor and not a FET) could blow because the overvoltage, for example.
If the backlight unit is on the same panel, search the fuse and desolder it. Or simply cut through the power wire leading to the backlight.After the experiment, solder the ends together again.
Although, there are at least three customers with the same error, it must be a warranty problem.
miak69, that's what happened to my monitor!
I remembered reading somewhere on the forums that the "egg" thing on the cigarette lighter lead is dodgy and it's better to run it off the regulated powersupply (i.e. the opus) on the 12v rail. That's when it died.
Why did it happen? too many amps or something? Anyway, I tried soldering a replacement capacitor on the board, but it didn't fix it. I've given it to a tv repair shop and they've had it for weeks now and keep telling me that they'll fix it by the end of the week, but they dont seem to be getting anywhere. pretty frustrating.
It's a new monitor that i bought off a reputable seller off ebay (well, as reputable as you can get on ebay...), but i figured the warranty was void as soon as i used a non-standard power supply unit (i.e. the opus or an atx power supply)
The repair shop haven't told me yet what the problem is, only that it'll be hard to fix. hopefully I'll find out more details tomorrow.
I'm almost ready to just buy another one off ebay and be done with it & cut my losses
Besides capacitor the microchip U2 or U1 usually blows as well.

I have the same problem. Fried mine tonight. Any news?
