Most likely it going to be a power supply related problem. The red blinking light is a code for a TV tech to diagnose the problem on the main power supply board itself or the board that regulates the power for the screen. Some manufactures call it a Backlight Inverter Board. A TV repair shop should be able to look at it for you and tell you which board is bad.

I have a Seiki 55 LED tv model LE-55GB2. This morning when we turned it on the tv screen started flashing and sound was going and coming. But it started working.


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

We have a 50" projection tv. it was manufactured in 1995. tonight we were watching it and it went black. the on/off button was flashing red. is it worth getting repaired


I won't pay more that $50 to fix a 15 years old projection tv, and no body will go to check it for less that $120 just to see it.
Did you try to unplug the power for a few seconds.

How old is this TV?
My experiance is to not put money into a TV that is over ten years old. TVs stress out their electronic components worse than almost any other electronic product. After 10 years, there are so many parts that are ready to fail that your are probably wasting your money trying to get any more life out of it.
Another option is to wholesale replace the main board from an outfit like Module Exchange at 972-298-1212
Be careful on buying a new one though. Often times, these new technology ones are much worse. Always Google the model number of the set you intend to buy and add the word 'repair' or 'complaint' to see if it is one of the many models that are customer service nightmares being produced by even the most reputable companies today.
Hope ya fix it!
