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.

Sony trinitron xbr screen periodically goes black. The audio stays on but the video cuts out.


Sony sets have several protective circuits that blank the screen if something happens that might damage the picture tube. One of the more common causes is trouble in the vertical output circuit. Given the age of your TV (the XBR models have been around a while), this might also be a symptom of a picture tube starting to fail. Most of these sets have circuitry (called AKB) that adjusts the color drive signals to the picture tube to keep them balanced. If one of the colors is enough out of range the screen will blank. It might be the tube itself, or failure of some part in that AKB circuit. The set might also have defective parts in the input switching or video processing stages.

Unfortunately, I can't suggest any place you might look if you want to try repairing this on your own. This kind of trouble usually needs to be diagnosed and repaired by a professional TV technician who has the service information to track it down.

Hope this has been helpful. Thanks for using Fixya!

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 Trinitron XBR, Stand By Mode?


The 6 or 7 blinks usually indicate a problem in the horizontal circuit. Since the TV recovered once, the problem is most likely to be a bad solder connection in that area. If you can solder, resolder any connections on the board that appear grainy or have rings. That may resolve the problem. If not, update this and we'll look elsewhere for defective parts.
