Re: Sony kv32v15, Red screen with fine horizantal lines...

I would suggest to measure the 200 volt B+ at the CRT socket. If that voltage is found to be low, disconnect the socket from the CRT and measure again. If the voltage reading returns to normal you may have a defective CTR.
Also check for open or defective diode on flyback transformer for the 200 vdc source.
I would also suggest to take all the necessary precautions since you are working in a very high voltage area.
Good Luck.

Your tv has problems in power regulator side, which is in the printed circuit board of the telivision. Sometimes it may due to some socket contact problems. You just contact a technician., while you cannot do it right by yourself.

On older Sony, sometimes a power surge causes the set to be in shut down mode. Try unplugging for 5 minutes and then plug in and try. This many times will fix.

Sony TV shut down

Sony sets have internal diagnostics. Unless the ste is 100% dead, you should see the standby light blink in a pattern of count,pause,count... Please supply that count here and I can give you details about the problem.

TV shuts off and red standby/timer lights blinks red until I power the set off. When it shuts down it does so with a very loud snap. When I turn it back on the screen is blue and has light blue...

The most common cause for what you are seeing is a shorted gun in the picture tube. When 2 elements (heater and cathode) of one of the guns inside the neck of the picture tube touch, that gun goes full on and overloads the flyback (high voltage) transformer. If it is in the blue gun, the screen will go bright blue with light blue "retrace" lines in it. The computer senses the overload and shuts the set off. At 2 years old the tech most likely tried removing the short by arcing between the elements. This works sometimes but the short often comes back a few months later. Another attempt at removing the short could be tried, and it might work this time, but it may or may not work for long. The ony other solution is to replace the picture tube but that would cost much more than the set is worth. A qualified tech will be able to tell you if this is the problem in your set.
