THERES TWO ^POSSIBILE REASONS YOUR Y MAIN BUFFER BOARD FLEX CONNECTERS ARE DIRTY, FACING TV THE EXTREME LEFT BOARD OR YOUR PANEL IS DEFECT

You burnt out the backlit lamp. unfortunately there is no easy fix for this. If still underwarranty great, if not... it will cost more to fix it then buy a new tv probably.

To determine what is causing our TV to lose it's picture you would have to do some basic troubleshooting. The areas of concern for that particular model with that issue would be the Power Board, the connectors to the board, fuses on the Y & Z Boards, and so on. Once you have run the tests to determine the parts that need to be replaced you would need to find out the availability of those parts in the area that you are from. The TV is of the age that the cost of repairing it may actually be more than the cost of purchasing a brand new set. Due to downturns in the economy sales of plasma, LCD, and led TV's is much slower than anticipated. This has brought the cost of the new units dramatically.

In closing, do your troubleshooting to identify the parts that need replacing and check their cost and availability. Compare to the local cost of a new TV and that should help you to decide which way to go.

OK.

Y-sus and X-sus boards have failed. The plasma will not illuminate because these two boards are faulty. You will need a direct replacement for each and you MUST replace both as they work together to light the plasma screen.

What you most likely need is this:

There's a minor chance it may be something else, but with the sporadic problem appeareance it would be impossible to diagnose remotely.

This is the most likely reason for similar problems, but, I repeat, no guarantees.

I am not anyhow affiliated with whoever is selling this. You may be able to find better deals elsewhere.

ru model tvs are usually dlp which means you will need a lamp replacement the instructions are in the user manual and lg will be the best source for the replacement part.

In the absence of audio and video, the likely culprit is the main power supply which services both. Plasma sets use an output of the main supply to produce the high voltage required by the plasma display which has attributes similar to the older CRT displays in the use of high voltage and internal phosphor to convert electron flow into light. The main supply may be a separate assembly. If you feel adventurous, pull the AC plug overnight and remove the back panel of the set. Look for a smaller board with fewer, but larger, components on it. There may be another separate smaller board that produces the high voltage for the display but it is probably OK but not receiving service voltage from the main supply.
If you can find an assembly number on the main supply, you may be able to buy or exchange it for a repaired unit and do the swap yourself.

are you also aware that this is a common problem with 42" LG Many were recalloed for this fault. Get onto LG and see if you can get it replaced under recall.

Thanks for using FIXYA

Present your case to LG customer care ASAP. So close to out of warranty, they may at least cover parts. you will almost certainly in the first instance be referred to an authorised repairer.

You should return it. The Plasma display is vibrating. Mfgs found this out by sets that were moved from sea level or 500ft above to Colorado. The vibration was terrible. I have not heard if that problem has been rectified or not. In any event, return it.

not the problem is the y-sud board

This will be your Y SUSTAIN board on the left hand side when you take the back off.
Plenty available on ebay, Very easy fix

Hello sir, looks like your LCD inverter board is toast. this board is responsible for the back lighting of your TV, if this goes so as the lamp. your screen is blacked. Have this replaced by your dealer or check if they have service.

Is this the case for all inputs on the TV? Meaning with regular TV viewing, DVDs, and anything else that you have attached, everything displays no picture whatsoever but sound works? And this is definitely coming from the speakers in your TV not surround sound speakers, correct?

Also, when you press a button such as MENU / SETUP, or even VOLUME UP / DOWN on the tv's remote does it appear on screen as if it is doing that function? Does that part of the video display work at least?

Please let me know, just reply to my answer here and I will continue to help you for sure..

Thanks,
Tim
