Question about Samsung HL-R6167W 61" HDTV

1 Answer

Projection tv has really loud buzz or hum

I have a GemStar 56' rear projection tv. It turns on just fine, turns off just fine. I have a clear picture and no visual picture defects. Therefore i don't believe its the color wheel. But i do think the sound is coming from the projector somehow. Its like a whining sound and can only be heard when the tv is on. You hear it wind down as soon as you power it off. Any ideas as to what it is and how to fix it?

You may not see any deterioration in the picture when the color wheel begins to go bad. The noise will get louder and eventually, it will shut down or the wheel will shatter while the motor continues to spin. If that happens, you'll have a black and white picture.

If its a Samsung DLP that is mercury vapor lamp driven, its a safe bet the color wheel is going bad.

I have pioneer plasma tv about 6 years old. I turned the power on, sound but no picture. Do you think it is worth fixing?


no
plasma tv units consume considerable power and the latest led units don't so for the extra cost of a new unit , there will be a power saving over the years

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.

Samsung TV Displaying Dual Images. It appears as 2 of the same images offset from each other. There are also some lines in the images. Talked to samsung and they wanted to send a tech but I simply can't...


Overlapping video signals are generally adjustments made when turning various pots on the rear circuit board. You may need the service manual to follow the directions on how to reset and stabilize the picture. If you cannot be your own technician; you have no choice or other options.

TV turns on fine but turns off in 5 to 10 mins


Yes, this normal, by the lack of detail shown in your question. Once you press any key it should come back on unless it is set to turn it self off while in sleep mode. This is to protect the display from creating burn in setting.

My tv has gone some orange colour


Try unplugging your tv and anything connected to it - you might want to take a picture first so you have a reference. I would also unplug everything connected to the tv: cable, stereo, etc. Wait a few minutes, then plug in and re-connect everything.

You can also go into your TV's setup menu and adjust the picture settings - try restoring the default settings first.
