Our Sony WEGA 50" also made this popping sound and we suddently had no picture. We ordered a new lamp, followed the instructions, and everything's been working just fine. Searched Google for "lamp for TV model" and found excellent prices. Good luck!

PLease refer to my answer on the same question you posted.

This problem is caused by a shorted circuit board, the cutting off and on is a symptom of the that defective circuit board. With falt panel LCD TV's as big as 42" going for as low as $400.00 on sale it is not the best idea to repair the problem which may be more than that cost to replace.

Look for any loose contacts in power outlet, RC jack, cable and socket. If you have the same problem even when using different input devices, the TV needs servicing.

Check and replace the main power regulator board.

If you have the same problem with another input such as a DVD player, this TV might need attention by a qualified service technician.

Just unplug the TV from AC mains wall socket. Plug it back in to after 10 minutes or so. This must make the TV to a hard reset.

just replace the y sustain

guessing may or may not help---if the power board had bad caps you may have missed one that looks good and is not OR some other part on the board may be bad--my instinct in this case would be to consider replacement of the power board first if you cannot confirm every single voltage is coming out of it.

I see so many here with no sound/nopicture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have tobuy and try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.

Good day!!!Sorry but I can't see any previous questions from you to my email but anyways lets proceed to your problem..If you are watching TV shows and the picture is ghosting kindly try to play a DVD movies or anything that having video on your DVD if the picture is fine when you play a DVD movies your TV is in good condition you don't have to worry about..If the picture is fine when you play a DVD let me know and I will give you next step of troubleshooting..However if you play a DVD but still picture is ghosting there something wrong with your TV..If you are using DVR then when you back to TV it become ghosting..It is possible that you hit the wrong button on remote..you can also try to restore factory settings to correct all possible wrong set up and also to to auto scan your TV to get back all channels clearly..Hope it helps..regards,chester

Open the back panel. have a look at the power supply components. Look for abnormal component shapes. i have found bulged capacitors which cause this problem.

Please consult a professional technician, if you are a novice in this field.

All the best

It's the capacitors on the power supply, it's a common problem, either buy a capacitor repair kit (yes they make them) and have a TV tech solder them on, or buy a new power supply board (about $200) and remove and replace it yourself (it's that easy)
