TV is >10 years old. Failure mode is second-hand from my daughter, but while watching she described the picture slowly shrinking to a small circle in center of screen. Turn-off and turn-on worked very briefly, then the same thing happened. I tried unplugging, plugging directly into wall, TV does not respond to remote or power switch. No sound, no lights, nothing. Sounded like blown tube, except for the fact it came on a second time. Any thoughts? Thanks.

Re: Sony 27" XBR failure
I will suggest dont ise it until someone who is qualified comes over to give you an estimate,I belive you have a lot of loose conections in the horizontal driver and output circuits,power supply and crt board.Should not be expensive to repair right now.
Good luck.

Failure of the vertical deflection module/circuit. The tv will have to be opened, the vertical deflection circuit found and replaced.
Definitely a job for a pro - the circuit is going to be extremely difficult to extract. The repair will cost you about $200: $20 for a new circuit and $90 per hour for the 2 hour job.
This could be a scan amplifier failure, and there is a loss of high voltage to the CRT. Part of the power supply may have also failed. In these sets, if the CRT emission goes low in emission, or the CRT goes defective, the bias supply to the CRT will go in to protect.
An experienced TV service tech can troubleshoot the set and give you an estimate for service. Considering the age of the set, the cost of service may not be worth it.
wow. mostly all new set from the last few years have a dual tuners NTSC and ATSC and that would depend if or which set will get the better signal. Also remember that off air is analog and the sets are now design for digital.
The high voltage circuit also runs the horizontal deflection circuit
and much of the rest as well. The horizontal problems you describe were
a prelude to high voltage failure. If the TV is anywhere near 10
years old (how come you guys never give the age????) it isn't
worth the cost of overhauling the high voltage circuit. You might
be able to replace just the H.O.T. but the flyback is the source of the
failure.
We just experienced the same thing. My daughter was watching TV and it went dead. We could not get it to turn back on. I'm guessing that this model Sony TV had a 13 year life expectancy. I offered it to a local technician who refurbs and sells TVs, and he wasn't interested. He said he doesn't mess with anything over 10 years old because it's too hard to sell. We just went ahead and bought a new LCD HDTV. It's a shame though. If someone were able to fix the old TV, I'm sure a nursing home or non-profit facility could use it. Our only other option is to pay $15 to have it recycled.
Picture tube failure is rare problem. Your problem is powersupply failure and short circuit in deflection area. This is quite common problem. My sugestion is before you got this problem picture clarity and color clarity is better perfomance in your satisfaction means repair is better. Otherwise replace it.
