In time as the Sony Trinitron ages it begins to have power issues. While this can be true of most tube televisions it's the rate and severity at which this happens to Trinitrons that makes it particularly of note. Many Trinitron owners have complained of the Trinitron set turning itself off randomly and frequently. Some sets have failed to stay on for longer than a few minutes at a time. Eventually some sets will not turn on at all. These problems grow more severe with age.
Check the power cable running from the Sony Trinitron 32. Make sure the cable is completely inserted into the power connection on the rear of the TV as well as the local power outlet.
Disconnect the power cable from the electrical outlet, then plug it into a different connection. It is possible to electrical outlet has died, forcing you to obtain a power current from a different source.
Check the cable connection running from the cable/satellite receiver or VCR. If the TV is on but no picture is on the screen, the problem is most likely due to a connection issue.
Power off the cable/satellite receiver, then press the "Video" button on the remote control to switch the Trinitron 32 to the video input signal. Turn on the cable/satellite receiver and the programming now loads onto the television screen.
4 times standby light blink shows that tv got problem in vertical deflection section and probably vertical output IC got defective, need to be replaced. Replacement of parts in circuit board requires soldering work and expertise so call local tv repair shop guy if you are not familiar with soldering work. Thanks.
I have a Sony SRS BBE Trinitron (WEGA). The last few days when I tried to turn it on using the remote the Red Light would go on but the TV did not turn on. I would have to press the power button again to turn it on.. I tought the remote battery was just low.
Today when I tried to turn it on nothing is happening and the Red Light is blinking 9 times ??? I tried to unplug it and try it again, still does the same thing ???
If you are not a professional Electronics guy,it is beyond you to tackle this problem. otherwise log on to www.free service manuals.com and see the SONY Blink codes and also download the service manual.best of luck
And it probably won't - - A common problem for this unit is regulator failure caused by one or more instabilities in the SMPS...
Are you any good at replacing caps?? If so check C633 located next to Ic600 and test it for open.. If open replace it and that should restore unit to normal operation. If it's not open you probably have a regulator failure and my advice would be to take it to a qualified shop for the repair...
