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.

Hi, This can be caused by several different things. Among them are: tube failure, digital comb filter failure, convergence failure, capacitors failure, i.c. faults, power supply providing incorrect voltage.
Unfortunately, being that your tv is so old, there is very little that can be done other than get a new tv.
It is because the repairs will cost as much as a new tv.
I'm sorry your Sony gave out on you, but 10 years is a good long time in the life of tv's nowadays.
I hope you get another that gives you as many years enjoyment, or more!
Did you get your set fixed or did you replace it? My same set did the same thing. Turned it off for 2-3hrs after watching it and when I tried to power it up- nothing but the sound it would normally make just before the major power up, sort of a relay click sound. No picture or sound but the red light blinks non-stop.
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.
I believe you have lost the green channel leaving only the red and blue. It could be an internal connection like a solder joint or connector, or it could be component failure from the CRT to an adjustment pot. Being the set is ten years old it wouldn't be worth spending a lot of money on it. You can buy a 27 inch TV now for almost what a repair would cost. If the picture was very good before this probem you may try to get it fixed cheap. Otherwise it probably wouldn't be worth it.
My 27 inch TV's (A Sony and a Sharp) are pretty old and I would fix them myself if the picture tube was very good.
This may be a very good time to buy considering the discounts being offered. ;-)).
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
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.
Usually when the vertical starts shrinking slowly, it is due to capicators getting out of tolerance in the vertical output section of the chassis. If it can be adjusted out through a service menu, you'll probably need a tech with the right equipment to perform it.
