Your set migbe missing the high voltage that lights up the picture tube,you need to check for loose conections starting at the horizontal drive transistor and transformer ,then check the horizontal output transistor for short,it needs to be checked with a meter if the output is shorted it probably open a safey fuse or resistor to prevent more damage.If you are familiar with tv service this will give a place to star but if you are not too familiar be safe and seek the help of a servicer.Let Us know if you need more information.

The previous replies by techman and jomaru are probably the correct proceedure, but have you tried increasing the brightness and contrast to maximum ( this may be impossible with the on screen menu). Is there any static on the screen, if so the line time base and transformer would be OK. If you have good hearing, and no tinatus problems you should be able to hear a very high pitched whistle from the line timebase

SOURCE: TV has audio sound and no picture

Trung,
There are many possibilities and most of them have to do with the "D" board, Sony p/n# A1346948A but testing is something generally beyond the scope of those less than technically equipped. You could order the whole board and put it in but that might be more than the simple fix you wanted or you wouldn't be here. So my best advice is to take it in to a qualified shop and have them estimate and repair it.. I see 3 or 4 of these sets in my shop a month, Sony XBR, and they're still very much worth the repair..

1999 sony trinitron color tv -no picture-no sound.

Hello c_car,

What is happening is that the Shutdown Circuit is turning the TV off due to excessive current flow. The excessive current flow is most likely the result of a problem in the HV (High Voltage) section of your TV. This could mean that the Horizontal Output Transistor or the Integrated High Voltage Transformer has malfunctioned (developed a short circuit). I would advise that you let a qualified TV technician work on the set due to the nature of this problem.

I hope this helps,

Thank you,

32" Sony Trinton Wega

Count the flashes and verify that the model is KV-32FS100. The flash count will indicate the circuit in which the problem was detected.

Standby/stereo light blinking no picture or sound

My picture would go out after several minutes but I still had sound. I took the rear cover off and blew all the dust off with compresed air.I did this for a few times over several days nothing happened.I also took off the rear circuit board that attaches to the tube with a round pin socket and blew that with compressed air and put it back on. The TV has now worked for two days without the picture going out. It worked!!!!!!!!!!!!!! My TV is 9 years old.

Red-Orange Screen

If the screen flashed when the TV made a popping sound, then I would suspect an intermittent heater to cathode short in the picture tube. When this happens, it usually takes out one to three output IC packs located on the CRT drive board. Even if you replaced the defective output packs which are soldered in and attached to metal heat sinks to restore the picture, the CRT could short again and redo the damage. For a 20 inch screen it is probably not worth repairing.
