Question about Sony FD Trinitron WEGA KV-32FS120 32" TV

3 Answers

When we switch on our Sony Trinitron, the red light keeps flashing, audio comes on but it takes a very long time 3 min approx for the picture to show up. Also the clarity and colour of the picture has worsened. What is the problem and is it worth repairing? Thank you.

This could be a sign of hte picture tube failing. If you are comfortable accessing the set with teh back removed, try a screen adjustment as follows:

1) locate the flyback transformer (part with large red wire coming out the top)
2) There should be 2 adjuistments on that part labeled screen and focus.
3) turn the screen control clockwise just a bit

If the set comes on more quickly, than the tube is starting to fail. The adjustment above is a temporary "fix" that will get you time to locate a replacement only. Further adjustment will cause the picture to be washed out and may show retrace lines as well.

Hope this helps,
Dan

Adjust the screen pot at the flyback just a little bit higher and it will have display.

Try this .. Check for 200V if present on the PCB attached at CRT tube. My TV has this problem also. Just search for 220K resistor located near Hout drive for flyback. Inspect if ok.

Hi Matt.
I`ve been repairing sony tv`s for a long time now and i can tell you that what you described is sure signs of a weak picture tube.
And the price of a new picture tube makes it prohibitive to replace it. You could open the set and adjust the screen control on the high voltage transformer but it won`t last long. If you decide to do that , look for a transformer with a long and thick red wire that connects to the back of the picture tube , That is the flyback transformer and there will be two controls on it, you want to adjust the bottom control that is the screen control(the upper one is the focus).
Turn your tv on and slowly turn the screen control up until the picture shows up at a reasonable brightness level, if yout turn it to high or you may get retrace lines in the picture.
That may strech the life of your set for a couple of months .
Hope this will help. Merry Christmas

Sony Trinitron KV-28LS36U no sound or picture, the standby light flashing green and red but if i switch it on a little bit of sound comes and then switches off. how can i repair?


The unit is shutting itself down because a problem was detected internally. When this happens, the standby light should blink a repeated pattern. Please count the number of blinks and post the number here. That will indicate the circuit in which the problem occurred.

Thanks,
Dan

No sound or picture now


The set may have shorted the horizontal out put transistor since it kept coming on sometimes. This could be cause by the driver transformer arcing causing a "spike" in voltage going to you horizoltal out put transistor. Stargazer

You may have a bad solder joint on the horizontal driver transformer or somewhere else in the set. I found this problem with this transformer several times. Stargazer
