No picture on a DLP when you can see the lamp is working is ALWAYS the DLP chip. BECAUSE you recently replaced the color wheel, i suspect that the LVDS/data cable to the light engine was not plugged in well and has come loose. I suggest checking and ...

I have a Samsung hlp5063w dlp tv. 1- loud buzzing noise coming from the left side of the set (looking from the front). When I tap it the noise tends to go away and come back. So I'm thinking it's the cooling fan for the lamp which I just replaced. Would the color wheel act like that when I'm tapping the side of the tv? The picture is beautiful and there are no problems there. 2- If its the cooling fan, how do I replace it?


It is much more likely considering all these the wheel fails to be your issue.The problem is often described as a fan like or high pitched sound which since the motor on the wheel turns at over 12,000 rpm is likely to be the cause.Hin ... Samsung Projection Televisions

I turn on my tv and no picture comes on. It makes a vibrating sound for roughly 10 seconds and shuts itself off. The lamp was just replaced and seems to work as does the fan. I thought it could be the color wheel but i need to find out what it could be. Any thoughts would be appreciated.

I have a baird x47dtv and we turned it on today but had no picture or sound. the blue power light comes on and flickers as it should on startup of tv,however we are still not recieving a picture. i have replaced the psu's approx 6 months ago so i know theres no problems there,but am unsure which part i need to replace as it could be 1 of three things. 1 it could be the main board, 2 it could be the power invertors or 3 the screen. any tips would be helpful

We have a Toshiba 42HM66 DLP. It is at least 3 years old and the lamp had never been changed. Lately the picture has gotten darker and once the unit is on for awhile the picture starts flickering and colors are not right. We assumed it was the lamp. Changed the lamp and still the same problem. Called Toshiba, they could not help but said picture flickering is not a symptom of needing a new lamp. They suggested we call a tech and they gave us a reference. The tech came out and agreed the


Check if the flickering happens when you have the menu up on the screen. If the menu does not flicker it may be the source of the signal or the connections to it or probable the board where the connections are terminating at. It may also be a prob ... Flat Panel Televisions

I have a Samsung HLP 4674w DLP. The picture started to lose color and look like a negative image. Then it would get scrambled and eventually go out. Powering on and off sometimes fixed it, but only temporarily. Sometimes it would also turn off and on by itself. I thought it may be the lamp so I replaced it, but it did not fix the problem. Next I thought it may be the color wheel so I replaced that, but the problem did not go away. Also when this happens the Power switch will not turn the TV off.

Ok here you go, I needed to replace my lamp on my Sony KDF-50E3000, lamp XL-2500. Easy replacement, however now only the picture is HD and any words, at the bottom of the screen are blurry. The blurr comes in and out at times. Originally I took off the whole fron of the screen as I thought this was how to replace the buld as I could not find my manual. Do I need to clean the mirrors inside the TV? Thank you


Only getting HD has nothing to do with a lamp change. I would start by seeing if your antenna settings got changed. For example from cable to over the air antenna. As far as the blurry words on the bottom of the display, I think you didn't get the sc ... Sony Standard (CRT) Televisions

Picture lost color to greenish black and white and rapid blinking. Lamp indicator was orange for many weeks previous. rebooted TV and lamp would not come on. Replaced lamp, now it will not power up the lamp. Is this failure just about the lamp timer/counter needing to be reset or do I need a new ballast as well? I'd like to test the bulb independently if I knew what voltage/amperage/ ACor DC to apply.

I have a InFocus lp70+ video projector with a bad lamp. When I replaced the lamp the new one worked but when I moved it to a different room the lamp would not come back on. The lamp has failed a continuity test. Could a problem in the projector be causing the lamps to burnout or is it worth trying another bulb.


Hi. It is possible that the projector to send the wrong voltage out to the bulb, and that is what is causing the bulbs to go out. But more than likely, when you moved the projector, it jarred things around in the bulb, causing it to fail. ... Flat Panel Televisions
