I do not know who was helping you before but the problem you are having can be caused by three boards in the tv each by themselves or in combination. Those are the control board with part#6871QCH053G, the Y- board part #6871QYH036D or the Z-board part#6871QZH041B. Without being able to do voltage and signal measurements directly for you, the Z-board is likely the culprit here. But I will tell you that even experienced tv technicians find themselves swapping one or more of the boards until they fix the problem. I am assuming here of course that you have not had problems with your tv before. The part #s I have given you are for the improved boards that LG has assembled to take care of future similar problems and come with their latest training manual for technicians. God bless and good luck.

Mines a LG RZ42PX11 it intermittently gets a black vertical line down the middle of the screen.


Hi I have a LG RZ42px11 there are 6 vertical thick black lines running down the middle off the screen, when cold the TV seems OK but if it has been on for around 10mins or on standby the lines stay on screen.

Thanks.

Sound it on and can change channels, but no picture. The screen is showing the set-up mode. I have called the cable company thinking it was the box, removed the batteries from the remotes, re-booted...


try reset to defaults:
  1. Press the 'MENU' button.
  2. Press the cursor down to select SETTINGS.
  3. Press cursor right twice.
  4. Press the cursor down to select RESET AV SETTINGS.
  5. Press cursor right on START NOW. Press the 'OK' button.
  6. Press the 'MENU' button to exit the menu.

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

42 inch LG Plasma TV - Lost picture


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

No picture, sound ok


I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.

Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

LG PLASMA TV WITH COLOURED LINES OVER SCREEN


If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it.
Good Luck.
