When i turn tv on green power light comes on couple of seconds later red light starts blinking numder of times it blinks is 8. when I turn power on or off I hear a click...all I tried was unplugging it for a couple of hours than plug it back in ...still no picture or sound.....hope u can help me..thanks
I went to servicemanuals.net and downloaded the complete service manual for this TV and found that 8 blinks means you need to check out the Panasonic-txnss1rltu-ss-board which I have had to replace once before on this set. I have found further that this item is prone to short life as a result of inadequate ventilation problems. Anyway, the part I need was easy enough to find in the service manual and ShopJimmy has it for about $43. So my problem is solved now.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

It's a power supply related problem.
The flashing 8 times is a trouble code. A Service Manual for your TV model will have the info on the codes. It could be a bad capacitor or a transformer on the power supply board.If you have some electronicexperience, you can find a Service Manual for your TV over the internet. Cost about under $20.

Problem: Samsung LTM1755B with only a blinking yellow LED when you try to turn it
Solution: I just had one of these come in. I opened it up, and found
the U501 capacitor a little suspicious looking, in that it had a
deformed top. It was a 470uF 16V electrolytic 105degC 10mm x 12mm. I
replaced it with a very good quality 1000uF 16V electrolytic 105degC
10mm x 16mm Nichicon UHN1C102MPD. After that repair, when I tried to
turn it on, the LED was yellow for a second, then green, then I got a
picture, and it appeared to work great. I then asked the owner a week
later how it was working, and they said it was working just like new!
If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.
