Warning: Based on information provided in several posts, and from talking to friends, it is very possible that you could severely electrocute yourself if you don’t know what you’re doing or if you touch the wrong part of the electronics. If you’re not sure it’s safe to do this then simply don’t. When I replaced the board I was very careful not to touch any components, including the underside of the board I was replacing. Of course, the unit must be unplugged before proceeding and it may be a good idea to let it sit for a couple of days before opening it.
A couple of weeks ago we experienced a power surge from a nearby lightning strike that damaged one HVAC unit along with a few electronics. One of the items that was damaged was our older 32″ Philips LCD TV. This was largely my fault. I used to have a surge protector on that TV but the last one quit working and I forgot to replace it.
When we tried to turn the TV back on it wouldn’t work and I noticed that a red LED, near the power LED, flashed 6 times, stopped, and then flashed the same sequence.
Last night my wife called me into the living room. She had been trying to watch something on the Tivo but at one point the television screen began alternating between black and green. She tried turning off the TV and then turning it back on but each time it powered up it was flashing.
I powered off the Tivo. At first, it seemed to work. The Tivo startup screen displayed. But I guess when it switched over to a different part of the startup sequence the TV went back to alternating between all black and all green.
I tried switching to different inputs on the HDMI switch and even powered off the unit and unplugged it, but still the TV flashed.
Finally, I went for the more elegant trouble-shooting solution and did what I should have tried first.
I unplugged the television from the power outlet.
When I turned the TV back on it was working fine. I’m hoping this was just some odd fluke in the HDMI port and not an early sign of a soon-to-fail TV.
