Re: sony tv red flashes

LED flashes of 8 times are indicative of a "High Voltage Error" which means something along the lines of "T8005 is faulty. (D board)" according to the service manual. Most likely it will need a professional to look at it. A link to the service manual is here:

Re: sony tv red flashes

I hate to be the bearer of bad news, but you have a shorted red picture tube.It is not at all uncommon on sony rear projection. The gun shorts and the set identifies the problem and goes into shutdown. Usually there are diagonal lines in the picture before it shuts down. this is an unfortunate problem because this set delivers a great picture. The dealer cost of the tube is around $200. When the repair is complete your're probably looking at $400-$600. The only problem is that the green tube and the blue tube also have chance of having the same problem. It'a tough call . But from my experience , I have replaced the green tube and had the blue tube goe within a year. Scrivitron

My Sony TV shuts down after you get a bright flash of light from the screen. After it shuts down, the red LED light on the front flashes 8 times. What's the problem?

On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

Try this....

These sets have weak picture tubes, this may buy you some time. It is not worth changing the tubes in the set. The cost would be more then its worth. Try these adjustments until it completely dies. I have the same set.

Green flashes then tv turns off

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.
