Question about Dell E173FP 17" LCD Flat Panel Monitor
Monitor powers up and shows a picture and then goes black. Will do it each time you push the power button on the monitor.
These monitors are a pain to open up. The inverter circuit for the backlight is on the right side of the monitor when veiwed from the front, part is c5707(marked) or 2sc5707(actual part number) around $1, there are 4 of them, one or 2 usually fail. Sometimes this failure can cause damage to one or more of the corresponding transformers which can can be visibly be seen affecting(melted) the yellow wrap. Be sure to check for dry joints around the affected area as the boards are very badly made, primarily around these transistors and transformers or the fault could reoccur soon after the repair. The same fault occurs in the dell 19", part number is 2sc5706. I hope this helps you out.

I found one of these monitors in the trash, it came on with no picture the light was green, I found out it was the control voltage for the HV power supply, I tore apart an old VCR salvaged a PNP transitor and a resistor and hotwired it, the only downfall is the brightness doesn't adjust but I assume the resistor value would have affected the brightness, if I needed it brighter.

Well, that's my impression to ;-) As I have same basic knowledge i electronics and I suspect the capacitor, I would like to open the panel. But these modern plastic panel has few screws.. and some secret to open it. Short, I did not find our how to open it. Does anybody have any hints for me how to open it correctly? Thanks!

The backlight bad or the inveter board.

I used a company that sells the entire inverter board at a very reasonable price. I installed a new board and then shipped my old one bad and had it repaired for a backup. Here's the web site;
These guys are great.
