Very Happy

I have a 32" Sony projection TV. Latley when I turn it on I am getting sound but no picture. After several min. the picture does come on. Does this mean that the tube is going and I need to replace my TV, or could it be something simple?

If it's an old one , around 8-10 years, and used a lot, it can be the tubes.
Other version can be the weak ELKO-s in the PSU./POWER SUPPLY/.
Try to gain the G2 voltages on the tubes, till you see the retraice lines.
If it can not reach a certain limit , the tubes will not open, that's why you don't see light , only sound.

Good luck

You say 32" projection TV. I'm unaware of a 32" projection TV. Should have a picture tube. Resolder the vertical ic. If that's not it bad solder in the horizontal circuit. Driver x-former, hot, and so on. Will blow out Q601/602 R607 and HOT. If I'm right. What's the modle #?
