Question about Samsung HLN617W 61" Rear Projection HDTV

1 Answer

3 blinking lights and no picture

After turning on tv, lamp light comes on as green. A high pitch whine starts and lasts for 3-5 seconds as if something is trying to start up. Whine stops and recycles 3 times total. Set shuts down and 3 blinking lights come on in front of set. I have replaced the bulb and the ballast with no improvement.

Re: 3 blinking lights and no picture

The whine or squealing you hear is either the color wheel or fan. To determine which, when the noise is heard from the set, turn it off and listen carefully. If squealing stops immediately then Tthe fault is the color wheel, not the fan. And sounds like that are generally the color wheel. A new color wheel is Samsung p/n# BP96-00250A for this model. Vance Baldwin carries them for $97.20 plus shipping. Logon as guest, select parts and copy past the above part number in without any dashes. Good luck... Bill

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 !!

Rear projection tv wont come on. PLEASE HELP

If the set uses a lamp it MAY have a color wheel--when they fail you get a high pitched whine and or grinding sound--also often described as a fan like noise.

this is a part of the optical light engine and may not be sold as a part by itself.

If you remove the lamp and look where it faces you should if it is there be able to see it--missing any pieces or shattered and it is bad.

Hlp5063w lamp and temp lights blink and tv doesnt turn on

Look at turn on to see if lamp fires even for a second.

If lamp has not been replaced in 2,000 hrs it is a suspect.

If you heard a high pitched whine or fan like noise before the set failed remove the lamp and look where it faces----is the color wheel shattered or missing pieces?

Tv won't turn on. It blinks green then red.

Question shows tv is Sony KDF-60WF655.
Green light blinks when tv gets prepare to fire up lamp, check internal circuits then show picture on front screen.
Red light blinking shows some kind of internal problem during circuit check and protection got activated upon some failure.
Count the red light blink as you will see 3 second long pause and post it here to diagnose what section of tv got problem.
Did you replaced its lamp in last 2-3 years?

Why does my samsung tv cut off by itself after 1-2 min and flash a red lamp button?

A little explanation first- this model (as do most Samsung DLP sets) will try 3 times to get the lamp lit before the microprocessor will give up and then the 3 lites on the front will blink indicating a LAMP failure. This process takes about 1 to 2 minutes. In order of probabilty, the failures are:
1) A faulty lamp and/or ballast. REPLACE LAMP AND/OR BALLAST
However, a faulty lamp and/or ballast are not the only things that will give this blink code-
2) If the color wheel has a bad bearing and turns too slow or not at all, the microprocessor WILL NOT let the lamp light, and then give a LAMP blink code. A bad color wheel will normally have some sort of abnormal sound- a low growl or high pitched whine is common. REPLACE COLOR WHEEL
3) ALSO, if the microprocessor (on the DMD board) in its color wheel rotation detection or processing fails, once again the lamp is prevented from coming on and you get a LAMP blink code. REPLACE DMD BOARD
IF THE SET EVER COMES ON WITH A PICTURE for even a fraction of a second or though it takes many tries, the lamp and ballast are good. The problem must be either the color wheel or DMD board.

RCA HD61LPW42 - no picture

I haven't worked on an RCA DLP but have on Samsung DLP, based on your description it sounds like the color wheel is bad. Take the back off and turn on TV make sure its not a fan making the noise ,but most likely its the "wheel" it is inside the light engine probably right next to where the lamp is plugged in. If the whine comes from this area definitely the wheel.

The colorwheel is your problem. To confirm this, unplug the tv, then listen thru the air vents in the back as you plug the tv in. You will probably hear a ticking sound. If you do, that is the colrwheel. If the colrwheel is working, youwill be able to hear it "spin up". It will be a sudden high pitch whine. Let me know if I can be of further assistance

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
