    when you turn tv on the logo doesn't even come up, just a blank screen. A few days before this happened, the tv would lose a partial picture (bottom half then top half missing). Turned it on tonite, smelled that dreaded "somethings burning" smell and got no picture. Sound is ok. Second time this happened! This is a recond replacement for the first P.O.S.

Turn the tv with the rear cover facing you. power on the tv, look into the grills on the rear cover. If you happen to see 3 green lights together on the mainboard, you have communication signal. Otherwise, its the mainboard. If u get all 3, then its your Y main board and probably a lower or upper buffer, depending on where burn is located on panel board.

The problem is a $1.09 part. You will need a soldering gun, multimeter, etc.. Or someone else who is electronically inclined.

The fix for it is here:

I have the 46" Dell model with the same problem, Dell Logo all pixilated and fading out to black screen, and this fixed it. Part cost $1.09 plus shipping.

I can't take credit for this persons post so post thanks on the fix.

Just note, TV's can hold electricity even after being unplugged. So if you try this keep that in mind. You shouldn't mess with it until an hour or so after you unplug it and even then there could be electricity in the large capacitors that can harm or kill you. Google "discharging capacitors" to discharge the electricity from the power board. Attempt at your own risk.

Screen issues :(

Sounds like the Y-Buffer board, not the housekeeper sadly...

Most common part that goes bad...

Dell will charge you $1200 or so to just look at it...

Mine was 3 days out of warrenty.. Dell told me to go pound salt..

If you can find someone to look at it... Here's the part number that might be bad...

Phone Number: 1-866-925-7278

PCB: LJ41-02760A - $84.36

And yes... Dell 42", Sanyo 42", Phillips 42" , and Samsung 42" Plasma's all use the same parts.

the problem was the y-sus board, i had a local tv repair shop diagnos that much for me. although, he couldn't fix it i did some research and found a company in california,, who could. you send him the y-sus board and the two buffer boards and he not only repairs them but he upgrades them. apparently the y-sus board gets too much heat and eventually goes out, sometimes the buffer boards are affected too. replaces the components on the y-sus board with better parts which are more heat resistent. i believe this will help you with your problem. let me know...good luck.

This is a common issue with HDMI. Try unplugging the TV for 2 monutes and also reset the cable box as well by inplugging.

Help - 15 mth old 42" edtv "plasma" black screen" have power and sound

First thing to check is if the back lighting has just failed... Power the set on and looking across the screen can you see a shadow of a picture happening? You might even use a flashlight to shine directly at the screen while you look at it from an angle.
