Hello :F Does your TV looks one of this??? http://i62.photobucket.com/albums/h109/hexadecimal_2006/TVD.jpg If it looks like the one on the top, like a shadow/discoloration, Is going to be a problem with the color wheel. If it look like the 2nd picture, like a LINE across the screen, that's a problem...

Jake

that could be a problem with your color wheel.
Since your color wheel is not working properly that's why it shuts down. Your TV cant complete the "turning on" cycle.

Jake

If i was in your place...the first thing to do will be to replace the digital board.

If that doesn't work... Ill just follow the path...until i fix the problem.

Jake

Press the Pause button, hehehehe... just kidding.

ammm...that's a problem with the light engine system.
To be honest i think you have to replace the full assembly ._.

that's my recommendation. Lets see if more people can comment.

Jake

I was viewing a program on my HL-R4667W when the screen went black, came back on momentarily a couple of times and went black for good. The three blinking indicator LEDs "suggested" that the lamp needed replacement. I tested the lamp with a VOM minus the then knowledge that it was a mercury vapor t...

Jake

ammm is it like a blob?

like a green blob on your screen???? or is it like a green line???

the only thing i can think is that you're going to need to replace your light engine.

Jake

what kind of noise is the color wheel doing??? is it like a buzzing, whirling or grinding sound??? If you touch your TV does it feel like it vibrates??? the picture is a lill small, it would be cool if you can post a bigger picture. What i can say is that...it could be either the DMD board or light ...

Jake

what kind of noise is the color wheel doing???

the picture is a lill small. What i can say is that...it could be either the DMD board or light engine.

Yes....you have to be careful, if you dont know how to do it...please dont do it

but with a voltmeter you can check the power supply.

Jake

i think you have to check the y and X sustain boards...

Jake

A power supply problem wont give you vertical lines on the screen.

ammm...for what i can say....it looks like the problem that you are having is with the DMD Board.

Jake

About the fan...try to clean the fan. Sometimes they stop working because they get stuck with dust.
In case that doesn't help try to replace that fan.

About the humming/buzzing sound...

Most probably is going to be your color wheel.

Jake

TV MODEL #: HD44LPW62YX1
Enclosure Part number:265919

LAMP Info: E22 120/132W 1.0 PHILIPS

Jake

I'm not an expert on plasmas but...

Check the power supply, maybe its sending to much voltage to the sustain board.

Jake

ammmm im not an expert for plasmas...

But, it could be...one of the sustain boards, power supply or the screen.

check the path in that order.

How old is the TV?

Jake

I think I may have this same problem with the ballast but wanted to clarify. If I unplug the TV and replug it in and hit the power button, I hear something spin up (color wheel?) and a few clicks followed by a continuous clicking that is fairly quiet compared to the first clicks. The "lamp" light f...

Jake

It all depends on the wattage of your ballast.

If you have a 100W ballast with a 120W lamp...your ballast will be short for 20W to ignite the lamp.
Basically it would not work...and if it does is not going to work properly

Jake

how old is your TV? Have you ever change a lamp to your TV??? If you already change it, when was the last time? do you hear any clicking sounds when you turn on your TV? Im asking this because the most common problems with a TV is... 1st LAMP 2nd Ballast and 3rd color wheel/power supply Also, try an...

Jake

mmhmmmm well i don't think is necessary to replace both boards...but i see it more like a suggestion, just to be on the safe side

Jake

You can check the part number that you need with your DMD board.

And yeah it looks like the problem that you're having is with DMD

Jake

YUP

The reason for that is because...there's an average hours of usage for the lamp. Now if you try to squeeze more hours to a lamp, basically you're forcing the life spawn of the lamp, making your ballast to work the double to ignite the lamp/ keep powered on.

Jake

Hey whats up....

Well for what you're saying it seems that nothing works ._.

I can say that your problem is with the POWER SUPPLY.

or....it could be a chance that it could be that the DMD board is not working properly D:

Good luck....check your power supply first

Jake

Lew

Its impossible to tell which color wheel you have in your TV, you need to check the part.You have to open it up

Jake

YEEEEY thank you :D well...it looks like a HUGE HAIR...or EYELASH. mmmhmmm... My recommendation. take out the enclosure, clean the glass from the lamp. Also it could be that the problem is in the optical lens or optical block. I can suggest you to clean everything with a can of compressed air you kn...

Jake

Well i checked the fix your dlp website...and got no results and also checked the internet...
No results D:

But il;l keep looking for it...i dont know if you're still looking for it

Jake

I'm not 100% sure, but it seems that there's a problem with a DIGITAL Board.

I checked on the DM website and found this.

Jake

Ok, you can try this: 1 Try to pull up the menu, if your menu looks ok. Then the problem is with Digital Board. 2 If you pull up the menue and the menu is also pixelated then the problem is with the DMD board I checked prices on Discount merchant and: Digital boards for samsung they run from 24 to 6...

Jake

Yeah a picture is going to help a lot. mmhmm.. This is the first thing i would do, since you clean that TV and "hunt" all of the dust bunnies. It could be probable that maybe some of the dust went to the lens from the lamp or lens from the proyector. I can suggest you to take out the enclosure and c...

Jake

yep... Try to clean the light engine and also the FANS... LETS HUNT ALL THE DUST BUNNIES :D also, something that always helps.... PUT like a FAN on the back of the TV or at the side...that way it can be cooling the TV If it works that way, then you are having a problem with HEAT. If it keeps giving ...

Jake

Or it could be your color wheel

Jake

well you're going to need a voltmeter and you can check your power supply, if its giving you a reading from 300-350 volts..then your power supply y working propertly

Have fun n_n

Jake

Replaced lamp but no difference. TV just went out. Power button has no effect no sound except the fan Hey whats up....ammm what i think is that MAAAYBE the color wheel is not working properly. Usually it does like a sound...but sometimes it gets confused with the FANS. ammm...try to check that...1 ...
