Ur LCD inverter it dead.must replaced to get picture back.

have you tried re runnig set up ? that might just take care of your problem if not then you will need a mainboard replacement

No, if ANY of the fuses were bad, the television wouldn't operate at all. I suspect that a technician will have to possibly make adjustments to the Y-sus and Z-sus panels to see if that helps. Possibly the y-sus panel is going bad or the plasma panel is going bad itself. Either way you need to have a technician look at the TV for you. Please take a few moments to rate my answer. Thank you.

Display is broken. Replace.

Most likely the LCD panel has detached one or more of the lines that go from the control ICs to the actual LCD cells.

It usually happens due to heat emitted by the TV and the lamps behind it.

There is nothing you can do about that. Get used to it or consider selling it.

I was able to pull a trick once or twice by locating where it was and pressing it hard by putting a firm object between the frame and the LCD then fastening the frame...it's not a good or reliable way to go about it though. Takes a lot of time and carries high risk of causing additional damage.

No service technician that I know would engage in doing it. I am more of a hacker by heart and my main source of income is not tv repair, so I did attempt it a few times and was proud of the result in at least one of them...at least for a while :-)

But bottom line is it's not worth doing it.

Of course there's a minimal chance that the tcon (LCD controller) board is to blame. But from what you describe it's unlikely.

The fuse you have replaced would have been on the sustain board, now that it clicks indicates a problem either with the control board or the sustain board. You would need to disconnect the connector from the power board to the Y-sustain board (left of power board) to check if the Vs & Va voltages are present, if so then the power supply will be working ok & the problem will be with the previously mention boards. There is the possibility that the plasma display screen could also be faulty.

There are a lot of possibilities. If you could give a lot more detail that would be great. Also how long have you owned the tv? Does the tv turn on at all? is there audio? Does the onscreen menu come on? Once I have more information I can assist you further.
Thanks,

Sounds like one of your y-drives are bad. It could be a loose connection between the y-drive and the PDP module(PLASMA panel) but most likely you need to replace one of your y-drive boards. They are what put the horizontal picture on your TV.

You can download the owner's manual for free from LG's website in PDF format.

If you need a service or training manual for the TV, you can also get them from LG or many other 3rd party website but they will charge you (usually around $20-30).

Hello,

This may be a connection problem. Here is something to try:

Turn off your system and check the connection to the HDTV system and make sure the cables are plugged in correctly. Then check the connections from the HDTV to your Cable box or Receiver.
Then turn it back on and see if it comes up.

Good luck,
SH

I'm afraid not, this will be a defect within the screen & the only remedy is to have the screen replaced.

please change vertical ic oc decosition coil solderd

it has power section in side your tv .We called it power adapter

Please check if you have turned the wide feature ON. Wide feature would make the picture wider.

Hope this helps.
