Check whether the filament of CRT glow or not. If not, check all the solder terminals at the CRT base card. If it glows, check all the voltages at the video output card, said above.

SOURCE: blinking picture

TV Repairman came out today to look at my Sony KV-36XBR250 today with the exact same problem - he was able to adjust the settings through the service menu, but said it was a temporary fix only.

The picture tube is going and the Sony circuitry has a "video mute" that it uses when it senses the tube is not warmed up enough. The degraded state of the tube causes the blinking on and off as the signal from the tube wavers.

He ballpark estimated the tube replacement cost well above the price for replacing the set with a 37" LCD, so it's going to the dump...

SOURCE: sony 32" xbr trinitron trusurround T V picture is black

Most likely on a trinitron tube if it is dark is the high voltage capacitor has blown. This is the device that feed the 30,000 or so volts to charge the tube, it attaches at the back with a clip and ****** and a single cable coming from it.

You can check easily if it is definately that as you will notice if you power the tv on and off once or twice if you get that static charge feel from the screen, if there is none there then almost certainly that is the problem.

A solution I found for our KV-32XBR200 was to press Setup on top of the set, then select the "Demo" item with TV/Video. The text overlay apparently banished PIP. Verified this twice, as I'm at this page because our remote can only turn PIP on :-).

I recently bough a used 40in sony trinitron xbr. i have the DVI to HDMI cable but wether its my laptop or xbox the sound wont come through the tv at all. any suggestions?


Check the audio cable it might not been connected securely.

Could also be missing.

Even with the HDMI you may still needs it ( DVI is for video only).

DVI means Digital Video Interface.

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.

Sony Wega Kv-36XBR250 screen blinking


I have seen this flashing before, this could be an indication that the picture tube is weak, what happens is that if the white balance is off there is a circuit called akb it monitors the kathode of each gun and if they are not in balance it will attempt to balance it out. if it can't the picture will begin to flash, sometimes in some models the power light will blink 5 times. On some models the power light will only flash if the tv gives up trying to compinsate for white balance and shuts off compeletely. If you see the tv shutting off with 5 blinks then you know for sure it is time for a new set.
