Question about Sony KV-32DX20 32" TV
Standby LED flashes five times at irregular intervals. Screen info displays picture mode, channel number and stereo/mono status at irregular intervals. Picture has faint greenish tinge. Any ideas? Just need to sound like I know whats wrong when I ring the service outlet so I don't get ripped off too badly. Thanks. Zakk
A few weeks ago my set started flashing to a black screen. Now a couple of weeks later, i have no picture, but the set turns on and i have sound. The standby light is flashing. I purchased the set in 2000 so it is seven years old. This is the first problem. Could it be all three of the bulbs? Could it be all three of the bulbs? no as you say that sound is ok that means your power supply &high voltage section is ok. please check chroma ic luminance section or system control section stand by ckt ihanks

for my post #108 for a step-by-step solution with pictures. $21.83 is all it cost me. I fixed my own TV as many others on that forum have. Feel free to contact me at email@example.com if you run into difficulties.

The 2 blinks is an indication of overcurrent. That translates into a short somwhere inside the set. since you can get sound but no picture, that suggests that the problem is in the high voltage section. The most common failure there is the Horizontal Output Transistor. This is a 3 legged part attached to a heatsink close to the flyback transformer (part with large red wire coming out the top). That part should be marked C5438 or something similar. Post the marking here and I'll give you the complete part number.

YOUR CRT (PICTURE TUBE ) IS GOING BAD . this is the most common way a sony tv crt fails . the tv is to old to make it worth a crt . but if your handy and carefull there is a way to get a little more time out of it . start with the tv cold , remove the back and look on the little board connected to the neck of the crt . there is a control marked "SCREEN " plug in the tv and cable and start it , with it flashing adjust that control , one way will make it flash more and one way less , adjust this no more than you need to , just enough to stop the flashing .NO MORE ! just be carefull the voltages in a tv can KILL . dont touch anything else in there and use a little inslated screwdriver to make the adjustment good luck .... if this answer helped please leave me 4 stars rateing , this high rateing will keep me in the paid answer department , thank you

To answer your question;
In sony tv`s the seven blinks(sony error codes)usually means a high voltage safety shutdown( h.voltage has exceeded 33k volts) and is usually caused by the power supply regulation and/or the horizontal deflection circuit.
Which means that some repair will have to be done before it turns on again.
Hope this help. Happy Holidays
