Replace the Ballast control board and reset the lamp hours (through service mode). Parts should be available through your local service agent.

I have a Samsung HL-P5067W/HL DLP tv. When I turn it on cold the lamp light blinks on and off. The fan makes a high pitch sound a relay clicks the TV goes back to standby and the lamp light starts blinking...


This sounds like a lazy lamp--that is getting hard to start. Try a new lamp first. If you are inclined to do so--get a bard bulb and install in the old lamp housing and save some money. Get a real PHILLIPS bulb--it will last a while--compared to cheap generics that are good for maybe 6 months !!

Tv keeps shutting off. Currently no soud or picture


The set has a color wheel which may be bad, it often makes a high pitched or fan like sound prior to failure--it can even be a grinding noise.

I would with set unplugged remove the lamp cartridge and look where it faces---the color wheel can be seen.

What you are looking for is wheel shattered or missing any of the colored segments? If wheel does not turn or runs too slow set will detect this and shut lamp off etc.

Might the projector bulb still need replacement even if it lights up for 30 seconds


Possible but not real likely---do you hear any high pitched sound when set operates?

The lamp light was on. Had sound but no picture. Theres a high pitch whining noise that comes on as the bulb tries to light. Bought a new bulb, put it in, closed the door but nothing changed.

Tv Shuts off occasionally 1min upon power up shows red lamp light


Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.


Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
