This is an unfortunate tragedy for your tv. The part is listed by encompass part source for your LG plasma tv. Part # EAJ41988092 PDP module is $ 1,087.45. You may find it cheaper to shop for a new tv. If this was accidental does your homeowners cover this type of loss ? People please wear your Wii remote wrist strap!

you are describing a power supply defect. IT may be as simple as the main fuse. I believe the one in this set is a 6.5 amp located on the ps board right by cord connection. IF after replacing the fuse opens a second time you will need to replace the power board.

I suggest to be examined by technicians in a service center. If the price of replacement parts almost new price, better buy a new TV.

there is a thin wire that controls the input output of the power button on the board, and you may have a problem with it, best suggestion to offer you is to have it serviced by LG technicians.

You can do this only with the factory remote by going into the menu and options menu.

usually is an issue with the power supply or power inverter for the tv. basically one of the capacators is not holding a charge like it should and is causing the power to drop. contact a repair technition or begin looking for a new tv.

You need a VGA cable (15 pin) connected from PC (monitor out) to the PC input on the HDTV (15 pin) this is for the video. For the audio, connect from PC to HDTV, audio cable, either 3.5mm from earphone out on PC to HDTV 3.5mm audio input (next to PC VGA input) and also be sure to set PC screen resolution to compatible output for HDTV like 1024 X 768 or 600 x 800 etc.



Select the PC input on the HDTV using TV remote.

Hope this helps.

Electrical short, which has fried the MOSFETS... Normally these are meant to "break" and not allow any more voltage through, in this case they have broken and fused, still carrying voltage.
This is not cost effective to repair as many parts have been effected.

Hi fssidhom,

This is an indication of out-of-regulation in the power supply section, that's why you encountered the start-up problem. The very common caused of this fault is the leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit.It needs a little warm-up to make itself stable but the symptom will get worst. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Your unit will back to normal again if the leaky capacitor is isolated.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Also check if your unit is under warranty /extended warranty, avail it because the manufacturer of your unit will fix it for free. Don't open the back panel, this will void the warranty.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

Probably some bad capacitors in the power supply or inverter/RF circuitry for the back-lights.
look for electrolytics with the top bubbled up on them, or bulging plug at the bottom or leaking electrolyte...these caps all need to be replaced.

Ur tv are to much zooming in mode.Look on the remote control for a button that said like VIEW MODE,ZOOMING,PICTURE SIZES.Press one of these buttons to changes ur tv picture sizes.

Are you using a cable or satellite box to provide the signal to the TV? If so there will be a setting in the box that is probably set for the closed caption. Unless you are on the TV tuner input portion of the TV it will not allow you to adjust the closed caption setting.

Hi, you can try tightening the ribbon cables that run from the screen to the buffer board , only tighten the one near the line area. if this does not help you probably need a new buffer board or panel (screen) I’m happy to help further over the phone at https://www.6ya.com/expert/eric_ab7c09ec01841771

You can try to get the processor to do a cold start. To do this, unplug the power from the set - turning it off is not enough, you must unplug it!

After 15 minutes, plug the set back in and try to power up. If it works OK, you are good2go!

If that did not work, your set probably has a power supply problem. The best option if it is under warranty is to exchange it.

If your warranty has expired, find a good TV repair shop and ask for an estimate before going any further.

Good Luck!
