My tv just started to flash in and out of color. When it changes color I get this popping sound with the volume and then you can hear the program. This just constantly repeats itself. It stopped briefly the other day, then when I turned it back on today, the same problem was going on. Any help appreciated.

Re: flashing color in and out with popping sound
This sounds like the solder joints have cracked on the AFT can inside the tuner, a common Sony problem. Removing the tuner, opening it up and resoldering the grounds and small transformers inside should clear it up.

check for popped or raised tops on caps in power supply. also try unplugging set for 5 minutes and resetting it. How about does your color wheel spin up? if your color wheel don't startup then your tv will also shut down. also check all fans they all should be running at turn on. if all fails i would say its your light engine.
It sounds like at least one of 3 "IHVT",s popped. in short, a "IHVT" is a high voltage transformer. It will have to be replaced along with any other parts that were damaged in the process.
They do produce a strong odor when they pop!!
It is repairable but at a price. there is a good chance that parts will have to be ordered.
you might consider buying a new LCD HDTV instead of fixing this one.
