Hi , I recently had the same problem which I was determined to fix . So I did a few weeks of research to find that it was the Y SUS board which burns out. I'm sure you realized that the TV gets hot. Personally I think this is why. circuit boards don't like heat and I've learned that the cooling fans are a joke. I replaced the board and got my picture back. I proved the fan theory because after the screen started to act up. I placed a cooling fan near the vent holes on top and the problem cleared right up,It also helps if you lower the brightness which helps out on the heat situation.I will soon be adding a fan with a temp. sensor. This shoud help if your screen has lines when you initially turn the cool TV on.then I have Some other costless solutions. Hope this helped these are great TV's and like our cars we maintain them not throw them away..................................Mr Wiseman

I have an LG 60 inch plasma model 60PV450 that has no picture but does have sound


It is probably the backlight inverter board. These are common problems on all LCD and Plasma units that use fluorescent backlighting.

Heard a pop noise from LG 60PC1D tv, tv shut off and now the picture looks like a negative kind of...what is wrong?


Capacitor on the power supply popped and it is not allowing the proper voltage to be reached to the main board. This is messing up your picture. I would repair it before you create more damage from the blown capacitor on the power supply.


Please rate if this helped :)

Picture went dark


This problem can be a bad YSUS or bad ZSUS and I recommend replacing both. The part #s are 6871QYH039B and 6871QZH044C. These parts can be found at Andrews or Vance Baldwin.

Hello

Check the contrast settings
If you are a Technician than just check the video supply from 150 to 200 volts at all three RGB Cathodes in most of cases there would be dry soldering in others it could be due to failure of supply resistance check base biasing voltages if u can provide more information then I could pin point the fault

Good Luck
