    fuse is ok,does not loose power just shuts off, as if power button were
    pushed. returns to on pos. upon pushing power button.

    not sure, after 3 or 4 cycles of off/on tv stays on for extended
    period of 2/3 hrs. then may or maynot fail. as if it needs to warm
    up to stay on.

    1. The main filter capacitor or other filter capacitors in the low voltage
      power supply is dried up and this can cause all kinds of regulation problems.


    2. The power supply regulator is defective (or marginal) allowing excessive
      voltage on its output and then the X-ray protection circuitry shuts you down.

Samsung TV model LN32A450C1DXZA, after turning the TV on it will turn itself off shortly after and then turn itself back on shortly thereafter. Then it repeats that several times before staying on.


Hi there,

If the tv is still under warranty, this can be repaired at no charge.

However, if not under warranty, you will need to have the CAPACITORS on the main power supply circuit board tested (or replaced).

The capacitors responsible for the power supply can sometimes fail - open the back panel. If the capacitors on the main power supply board look too fat, or signs of burning near the solder joints, then you've found the problem.

Hope this helps.


Cheers,

Scott

Samsung DLP has no sound for about 8 minutes when first turned on.


Mine does the same thing. It makes a regular popping sound that does not change in level with the volume control. When the popping starts getting erratic the pixelated sound starts and in a short time the sound straightens out for the rest of the viewing time. However, the next time the cycle repeats itself. Did you find a fix?

TOSHIBA dlp projection, model 42hm66 won't stay on


Could be the power supply. You can check the power from supply with multi-tester or voltmeter. If have a service manual, then I suggest testing the ballast as well

Had a power outage while watching tv. Then 3 blinking lights.


This is an on-going problem with DLP sets. Normally you shut the set off and the cooling fan cools the lamp down and then it shuts off. In your case, of which it's not your fault, however your lamp has taken a major hit by not properly cooling down, in turn, you need to replace your lamp at this time.
I suggest in the future if you have an electrical storm and a chance of a power outage while your watching tv, I would'nt play that model or any other model of a DLP set.

Samsung DLP 62 inch turns off by itself after being switched on


take off the lamp access door on the back and find the safety switch that the door pushes on. unplug the connector from the switch and put staple into the connector to short out the cable. Switch is probably bad. worked for me. same problem.

Tv powers off and on after operating for about 1 hour


Same happened to me with my old panasonic set. It was a dry-joint. You can try re-soldering the circuit.

Good Luck.

P.S. - Check the Power Suply area closely.
