Actually the issue could be either with your color wheel or with yoru ballast, if you hear buzzing, whirling, whinning sound, it's most probable that the color wheel is defective, but if you hear a constant clicking sound the issue might be with the ballast, discountdashmerchantdotcom, free troubleshoot. You might ask yourself why could the other two parts affect the image, he thing is that since they're part of the light engine system as well as the lmap and dmd board, when one of the doesn't work, you won't get an image, since you could say they work together

Samsung HLR5667wx/xaa. Power surge took out tv. Replaced bulb and the bulb works, but tv wont come on and lamp light is flashing.


Hello, it sounds like the color wheel may have failed. Was there any noises, like a high pitch sound before it went out? If the color wheel isn't turning at proper speed, the set won't start up by shutting down the lamp protection circuit.

Light is bright but the image rapidily switches colores. And this toggles off and on. Is this a bad bulb?


hi,
You have to check the color wheel of your projector. If the colour wheel dosen't sync with DLP then this type of complaint can occur. You have to remove and clean the color wheel and its rpm counter sensor. Have added the picture of colur wheel for yur refference.
OK

Just replaced burnt out bulb in Infocus 4805 projector. Great picture with new bulb but only black and white. Is this a bulb issue or something else in the projector?


This is most likely the color wheel. When the bulb blows, it can damage the color wheel. The color wheel is a wheel composed of thin layers of colored glass that spins in front of the projected image. It is possible to repair it with super glue, but the best way is to try to find a new one to buy.

My Samsung HLP4663W 46 in was making a buzzing noise for several months. I know it could have been either the fan(s) or the color wheel, but I never opened it up to determine which it was. Now the TV quit...


Great reasoning work! In fact, the lamp will not light if the color wheel does not spin-up. Fans will not stop the process of lamp ignition. Instead, a fan will be detected and a message will appear on the screen telling which fan has stopped. You need to have the color wheel replaced.

Is the color wheel fine if it is spinning? Can you see any light from the dlp lamp when the screen is off? I had a service guy come by to fix my dlp and he replaced the bulb with no luck. He said it was...


First You can look on the rear of the set and see the lamp light shine through the lamp door vents when the set is on. Second you need to replace the whole color wheel before the set will work. Third Color wheels may spin but not at the correct rpm and may shut down the tv and sometimes color wheels will emit a high pitched whine or buzzing sound indicating that the bearings in the motor are wearing out. But now that you have to replace the color wheel you will need to adjust the index delay in the service menu. I suggest having a factory trained tech repair the set.

Flashing in Blk,Wht, and a little color


Sounds like maybe your color wheel needs to be replaced. If you have noticed a humming noise in conjunction with the intermittent colors, then that is most likely the issue.
My 51" Vivitek started to hum loudly about 2 months ago and I kind of ignored it ,but it got so loud and annoying I had to do something.First changed the bulb and then bought a color wheel at www.vancebaldwin.com .Login as guest and then enter your model number into corresponding box.They have a few Vivitek parts.
I replaced my color wheel myself and it works great!
I'd be happy to help any way I can.
Good luck!

Hlp5063w 50'' DLP samsung Experiancing The Word LAMP green letters flashing for 20 second followed by clicking noise then shut off.. then repeats that same process twice then TIMER / STANDBY/TEMP/LAMP...


Sounds like you've already gotten into the repairs. The three major things that fail on DLP are the bulb, the ballast and the color wheel. If your bulb is new and you aren't getting anywhere, replace the ballast, if that is still a no go, then move on to the color wheel. If replacing those three doesn't fix the problem, you will have to whip out the multimeter and start looking for problems on the PSB. You can get a ballast on ebay for about $100. Start there. The color wheel should be very freely moving. If something is grinding and hindering the movement at all, you need to replace it. That grinding may not seem like much but it is likely enough to keep the wheel from spinning at proper speeds. The sensor then kicks in and tells the brain that there is a problem and the brain keeps the ballast from firing the lamp.
Good luck.

Broken edge of bulb- TV won't work


The color wheel was the cause of the loud whining noise. The only item in the set under pressure that could possibly pop is the lamp. The fact that you have the 3 lights on is the lamp failure indicator. The lamp driver or ballast can also fail and give the same light error but I have never had one to pop.I would replace the lamp for sure. Also the lamp as you know sits right in front of the color wheel so perhaps it popped and fragments of the lamp ended up on, near or around the color wheel

1. Look at the new lamp. make sure it still looks good. not broken with little glass pieaces in it. 2. When you turn on the tv, put your ear to the lower back part of the tv near the middle. Listen for the start up of the color wheel (a low high pitch sound only at the start up of the motor). If this is good you will here a ticking sound only if the lamp dose not light.

Now with all this info. If the lamp lights (as seen from the back of the set) and goes out after a few seconds and you did not here the color wheel spin up, the color wheel is bad.

If you here the color wheel spin up and no ticking sound, the Ballast is bad.

The ballast part no. 939P978010

The color wheel is not avialable from Mits. You will have to replaced the light engine. It cost to much. Just buy a new tv.
