TV Repair Questions? Ask a TV Technician
If you're getting a picture, then your lamp and color wheel should be locked and operating correctly.
But you describe a color wheel that isn't locked....and that would stop the lamp from lighting.
Does the picture freeze, maybe go black, then the color wheel keeps spinning up faster and faster, then slows down? I had one do that because the white plug on the color wheel LOOKED plugged in, but it hadn't LOCKED in....but that occurred AFTER I had done some work on the color wheel, not before like you stated.
Talk to me about that. Were you getting spin up sounds before you even took your TV apart, or AFTER?
Grab the TV cabinet...can you FEEL the noise in your TV cabinet?
That's a broken color wheel if you can feel it or even Hear it.
Gets loud and nasty. The worst one I ever ran across, BOTH the customer and I had to YELL our conversation to each other.
Other times a normal conversation suffices, and some vibrate the cabinet, some don't.
But vibrating cabinets is a telltale sign.
If you press the power button and then you hear -- "buh RRRRROARRRRRRR" (sounds like a piece of woodworking equipment in high school shop class) then it's color wheel related.
How you get a picture is surprising...most don't even light up the lamp with a bad color wheel. They're so out of balance they can't get to full speed to light the lamp.
Ok, here's a little "factoid" from my experiences...if the color wheel is shattered, it's off balance. If it's off balance, some of the times you "FEEL" it vibrate the TV's cabinet.
The color wheel does try to spin up to speed, if it can't get up to speed, it shuts down and trys again...usually about 3 times before it shuts off the TV and flashes the 3 LED lights up front.
That's what I usually expect to see and hear and feel....
However, if your lamp is lighting...then the TV THINKS everything is fine, and it can continue to run if ONE out of THREE restarts sends an OK signal back to the TV's micro. The TV only blinks the 3 lights if THREE attempted restarts failed to deliver an OK signal.
And a TV set like yours can spin higher and higher before it maxxes out and spins down again.
Overall...you do have a bad color wheel simply because of the vibrating cabinet.
We should replace it.
Two different color wheels dependent upon the Version number.
Version number is XXXXX on the right side of the cabinet on this sticker--
If there's no version...then it's the 01 since it's the FIRST Version.
Get that info.
Get back to me.
Umm, yeah...I'm still with you. Information retrieval isn't fast...it's pretty time-intensive.
You must know if your Chassis ID is L3 or L6
BP96-00674 is your part number FOR CHASSIS (L3)
Available here --
BP96-01103A is your part number FOR CHASSIS L6
How to know if you have L3 or L6 chassis --
Yeah...I have complete disassembly.
Tell you what, order the part. Later today when things slow down, remind me about disassembly.
I'll get those to you later because right now....my answers are getting clipped by your questions
I'm that way too....I don't like taking things apart and 3 days later I get the part and wonder where this part goes and that part goes, and how did the old part fit in....this way or that way?
You probably should have the part Wednesday or Thurday at the latest. So, send me a note then, and It'll take about an hour to get a bunch of pictures together showing you disassembly. I'll send a followup on my end to remind you.
Save this page in your internet software...it's easier to access the question that way and contact me anytime you want.
Oh, I see....you want disassembly NOW correct?
I can do that...
Here is your Disassembly instructions --
A couple of Key points. When you pull the ribbon cable out of the shielded board. Make sure the Foils point the same exact direction that the old color wheel's foils came out of the socket.
They point towards the back of the TV set when installed correctly.
The white wire on the color wheel....that's the speed sensor. Make sure it's fully seated in the socket, otherwise the color wheel will spin out of control and the lamp will not light.
Other than that, the color wheel is easily installed in the top of the engine. If the color wheel is shattered, use a vacuum to get all the glass out of the color wheel chamber.
That'll get you going.
