When a set is powered up, there are internal checks that are performed. The initial green light indicates that power has been applied. The flashing red light indicates that a problem was found that is preventing the set from functioning properly and it has shutdown to prevent further damaeg. If you can supply the model number, I may be able to provide additional details. Also, check to see if the flashing red light has a pattern. Quite often the pattern will indicate what problem was detected.

Thanks,
Dan

SOURCE: won't power, light goes green 5-10 seconds later red flashing light

Solution Found.

I had the same problem with my 42FD5994. It was working fine, then one day I turned the TV on and the front light turned green for about 5 - 10 seconds and then the TV switched to protection mode (front green light is now red and flashing constantly). I did some research and found out the the power board is faulty. I ordered a DIY fix it kit on Ebay for around $55 (includes shipping). The kit contains 5 high temp capacitors and a new IC chip. It also comes with a good detailed photo of the circuit board the components that needed replacing.

I also spent $70 at Radio Shack for some soldering gear and went to work. It took me 3 hours to replace the 6 components. The IC chip was a pain to remove, but one that was out the rest went pretty smooth. I had to remove two extra blue capacitors in front of the IC chip to desolder some of the leads.

After I cleaned the board with Isopropal alcohol (99% pure) to remove the excess flux, I inspected the solder joints to make sure I didn't solder some runs together. All looked good.

Next I put the TV back together and hooked everything back up. I powered on the TV and the same problem as before. The TV went into protection mode. But this time I heard the speakers pop and the screen buzzed. So I pushed in the power button to reset the TV. Next, I turned the TV back on, but this time when the light was green, I quickly pushed the power button again to power off the TV. I tried the TV one last time. I powered the TV back on, and with the remote I turned the TV on. Viola! It worked. The TV powers on great, and works like a champ. I am guessing that the first time I tried to turn the TV on, the new components needed a minute to energize. I also started the TV cold, I should have plugged it in for a few minutes before I tried turning it on.

So, I was successful fixing my 42FD5594 with the DIY kit on Ebay. I ordered it from California. The company was great, and Everything arrived well protected. I figured if this didn't work, it was time to get a new TV anyway. I can save the $2000 for another day.

bad components on the power board needs to have service tech look into blown capacitors or transformer on the power board inside the tv.

SOURCE: Tv cuts off and green light flashes

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.

Good luck!

Undo the back and see if the fuses are blown. Replace them if they are.

SOURCE: Lamp problem or else?

You need to get the ballast repair kit #LSUC0002 and replace the parts to your ballast.

I have the exact same TV, did the above this past weekend, and the TV works like new.

You need to know how to solder though. It's not that hard.
