There are a few things that can cause this. Your t-con board, the signal board or the screen itself. The most likelly and cheapest would be the t-con board. This is the board that transfers your picture from the signal board to your screen. You would have to open up your tv and get the part number from the board itself.You can get get parts for this tv at www.interliquidparts.com

with the TV off. press "Mute" "1" , "8" , "2" , "Power" on the remote (one at a time). But be careful when in there, you can change setting to keep your TV from ever working again.

Hi,
Please take out main board and power supply of set 1 and 2 and test them in set 3 as it is still working, swap set 1 and 2 boards in set 3 just to narrow down problem.
Set 3 got lcd panel (screen) problem as it is showing white vertical line and lcd panel is very expensive part that would cost you approx new tv price so I would recommend to utilize its boards to fix/ repair set 1 and 2
Hope this will help you.
Thanks.

The fault you have mentioned is caused by faulty capacitors usually those on the Power supply board and/or SSB main board. I would suggest that you take a good look at the board and look for capacitors with swollen or cracked tops. The problem is caused by the caps unable to sustain their charge discharge cycle for a long time due to lost or corrupt electrolyte.

I would have to say the inverter(The board that lights up the screen) is bad.Thank You very much!

try going to the tv itself and push the source/input button. you should go to the correct source to get your picture back. try looking for the input or source button on the remote as well. that should do the trick -gab

try to use a ups it is more reliable than avr bec ups has a avr to

Hello,

More than likely this will be down to your Y Sustain board has gone faulty, when the back is off your TV it is on the left hand side and will probbaly have a fuse that has blown, replacing the fuse will not solve the problem as it is the IMP under the heatsink that has gone faulty.
You should get the part number of the board from Ebay,com for a replacement.
Hope this helps

Problem solved. Tele scrapped. Finally found a human being on one of Sony's "help lines" who said, as it is quite old set, software couldn't cope with large number (198) of digital whatsits. Got a nice, and cheap, replacement from Amazon at 8:30 next day.

Samsung 32 inch LCD TV needs a stabilizer support or not? Can any expert answer?

i had the same problem, you'll have to call the samsung service center. You TV's part which looks after the voltage connectivity has failed. This majorly happens due to voltage fluctuations. The part will cost around Rs. 2800 and service charges will be applied by the company.

im afraid to say that your display has gone the best thing you can do is call the supplyer of the tv if its under warranty or call samsung. the cost of a new display will be 400 - 500 pounds so you may have to buy a new set.

You need to check the back light is still on when the screen is blank (check through the back).

If the back light is on, need to change the Powwer Board.
but,
no back light, need to change the inverter.

I think that better to check the cables of S/W module.
Please check the s/w board placed in or chipped by bracket.

If nothing wrong with external appearance, then need to replace the IR module or Main Board.

the line is a panel failure. its not fixable
