    my tv was working and a power surge occurred, now the red light flashes 4 times intermittently

  • casie115 Dec 03, 2007

    Our menue screen works, butnothing else. The power comes on, the light used to flash (which I know means theres a problem) but after leaving the TV on a while it stopped. I was told it was the video IF (intermediate freuquency) and tunner board. Appearntly they are not too expensive, but good luck finding the part, not even my local Sony support office carried it when I called today.

My Samsung TV doesn't show a picture, when there was a picture audio and remote not working. Which boards need replaced?

If there is no audio then most likely your main board. If your red power stand by light blinks less than 3 s then its the M/B. If its more than 3 s then its the P/B.

No power output or standby light flashes.

Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

The TV was working fine and all of a sudden the tv just turned off and now it won't turn on at all

It's possible a component shorted out, keeping the set from coming on. A fairly common part that goes bad in that model is a diode, D500 on the circuit board, and you may find a capacitor or two that is stressed also. I am assuming the power light does not come on or flash.

The picture will go black and the sound will go out. At the same time, the green power inicator will flash. Then the picture and sound will come back on for several seconds and then it will go out again....

My TV had the same problem. I called Sony yesterday and they told me to reset the TV. I did so yesterday, and it seemed to work. Here is the transcript with instructions:
Please turn ON the TV. While holding down the RESET button on the Remote control, press the POWER button on the TV. The TV will turn itself OFF, then back ON again. Release the RESET button.The TV will go thru the initial setup, and should work normal.

No picture

These sets have had, unfortunately, bad picture tubes. The gun welds tend to break loose over time.
