Hello, please check: 1) is the regulated B+ avail at collector of HOT? 2)does the base of HOT go negative when unit is powered? 3)have you examined the external PIN diode for leakage? I sorta recall from memory this circuit and the B+ path from original 165 volt source thru to collector of HOT is not a simple distrubution path i recall a VDR in second stage with a resistor to ground around 5.6 ohms this resistor will discolor or change value if the VDR is defective be careful there are several of these VDR's avail use only the correct one. Best regards, Arpi

Sony FD Trinitron WEGA KV-36FV26 Picture has washed out and it appears as if there is a film over the color. We have adjusted all color and brightness options and has been like this for over a month. Is...

If the picture is washed out showing poor color it is the picture tube that is the problem, overtime the emission from the guns gradually declines until the picture balance is lost and it progressively gets worse. I recommend you replace it since repairs would involve a new picture tube and cost more than a new set.

Sony Wega Triniton KV-32FS100 TV

For the last week my TV has been going to a black screen for 10 seconds or so then the picture returns. It has been continual. Last night it stopped going to black screen, but now the standby light flashes 5 consecutive times and the color went haywire. A lot of red and everything that is suppose to be black is green.

I did a soft and hard reset with no success. What's wrong and is it worth fixing? Bought new in November 2002.
