The question is very vague, and there are many things in the TV set that can cause this. In most cases the power supply is going in to protect mode because some components in one of the areas is going too far out of specs and causing some kind of failure. The power supply is shutting down to protect the set set as best possible.

It will take an experienced tech with the proper facilities to diagnose the fault, and determine the failed components that are at fault. In many cases with these sets, they will have to change a complete circuit board to service it.

Seems to me you have a defective control panel board.. Ovens should never do this. Time for the Serviceman right away, this could be dangerous if you are not home.

Daewoo dtq-206sc have retrace lines


if retrace lines at top of picture the issue is in the vertical circuit--usually a bad filter cap and or the output chip (most of the caps that cause that are 220 uf or 330 uf and connected directly to one pin on the chip.

If retrace lines are across entire screen---likely the master screen control on the Flyback is set too high--causes excessive brightness and the retrace lines.

Tv turns off and on by itself. when turned off, it shows bands/lines of color. what could be the problem?


high voltage regulation problem. when high voltage gets too high protection circit kicks in and shuts off tv. since high voltage is too high, you will see a glow with horizontal retrace lines. if you see red, green, and blue lines your convergence ic's are overheating. suggest local service center

SONY TV PICTURE TURN GREEN WITHOUT RETRACE


Picture goes to high green with retrace lines that shows picture tube is defective and requires replacement.
Usually in above symptom, TV goes to standby mode and standby light blinks when green raster problem occurred.
New TV is better option because picture tube of KV-34XBR960 would not be available any more.
Thanks.

Turns off after 30 seconds


i think the convergence amps are weak, or the akb circut has caused the tubes to go bad, google your model number to see if it is in the tube problem. sony made some projos w/ bad tubes in them. tv lasts only three or four years,no cause i had one

Switches off after 3 to 4 secs--little bright screen hor line and small retrace lines


On the my sony website, they said try unplugging the set for 3 or 6 minutes. Then plug it directly to the wall. If that don't work, and it won't; seek a service center. I have the same problem.

Next time we better buy Panasonic. Sony products fail ALOT. I had a 5 disc DVD Changer and it was defective and it was part of a class action lawsuit,

I believe this is the same sort of problem.

The sony Vaio laptop computer gets consistent poor reviews.

I brought an alarm clock and its back up battery never worked right out of the box.

I brought a cordless phone and the LCD display went blank.

I am so DONE with Sony.

Good name; Bad products.
