Hi James, This could be one of two problems. I can't narrow it down any further without having the set in front of me. 1. The plasma panel or the componets which supply electricity to the plasma in the panel have packed up. 2. The video processing unit in the set has gone. As for the cost of repair, if it's the panel, buy a new TV. It'll be cheaper. If it's the component that supplies the electricity to the plasma on the panel or the video processing unit, expect to pay between 300-400 as a conservative estimate for parts. Labour would be another 100-200.
The culprit will usually be the lower y-sus video board which is a common problem with lg plasma sets.
easiest way of finding out is to get a competent person to remove the back panel-remove the board and power the set up-if it is this board the set will display the top half of the picture only-when replaced no picture will be displayed.
these boards can be obtained on e-bay for between 60 and 90 pounds and take minutes to fit.

Your problem is most likely a fried circuit board. I always connect my good electronic to a back up battery. but your problem might have been storm or surge related, I would take it to a repair center and get an estimate.
On a plasma that usually means a problem in the power sections. You should be able to get an estimate from a repair shop or Samsung repair depot. On that size of tv it should be cheaper to repair than replace unless it is several years old. Usually on a smaller tv just out of warrenty the cost to repair is worth more than just going out and buying a new tv.
As long as you know your replacement cost and get an estimate you will come out on top.
This sounds like the panel itself is cracked. If this is the case, the set wil not completely power up as youi have seen. The panel can not be repaired as such, it must be replaced. I can rpovide you with the part number and cost if you can post the model number. Be aware however, that the cost of the panel may come close to the cost of a replacement set.
Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common problem are the power supply for the screen itself. Most manufactures call it a Blacklight Inverter Board.But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptom. You have a few choices: 1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself. 2. If by chance the TV is still under warranty, go that route. 3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15. 4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV. I hope I shed some light on the subject for you.
well it looks to me u need a new tv....all the details u give are pointing that ur picture tube is gone.....but call LG help and costumer line and ask them......u may get away from it to get a new tv make sure when u get a new plasma to extend ur warren tie to a max o 3 to 5 years and if this would happend u get it repaires for free.......cost for a new screen app 1000 to 1500 dollars
Hey graceylou, Unfortunately, the estimate provided by the repair technician may be correct. While screens can generally be replaced, they often prove to be one the most expensive components of any LCD or plasma TV. If you are in doubt of the prices quoted to you however, I would strongly suggest contacting LG directly for more information. Many manufacturers are able to provide ballpark figures for replacement parts, especially those that are the most prone to damage or susceptible to hardware failure.Remember that labor charges may not be included in any estimate provided to you by LG, so you may wish to confirm with your repair tech if these charges were included in the $1,200.00 you were initially quoted. Hope this helps you out. Sincerely, Aaron Go Ahead. Use Us.
