I've been using DWW700H for my carputing needs for almost a year now and everything has been working fine until recently I've started experiencing "blank screen" issues.

In the past, I only got a blank screen when the weather was really cold and the LCD took sometime to warm up but now its happening even when the weather is 80+ degrees. The strange part is that it does not happen everytime but randomly. Sometime when I turn on the monitor (by pressing the power button) it turns on instantly while other times (like this morning) it took 20 mins and many button presses for it to finally come on (even though it wasn't not cold today at all).

I'm powering the LCD via ATX-M2 and as soon as the carputer turns on, the power light on the LCD lights up (indicating that its getting power) but when I push the power button to turn it on........nothing happens.

Anybody else has experience the same issue ? Any idea how to fix that ? Could it be somehow related to bad battery (not getting enough power) or this ?
