Loud popping noise and spark coming from red projector

EHT arcing takes place. Never switch the TV on, until this fault has been rectified. Doing so, will make too many other faults to occur. Contact any service technician.

THis could be one of the CRTs (Color Tubes) is bad or the high voltage is leaking somewhere.
Toshiba projection TVs have history of yoke problems.
My guess is one of the CRTs is arcing inside. This TV has 3 CRTs red, green and blue. Replacing a CRT is not easy or cheap to buy if you can find it. If you like this try calling a TV technician to track down the high voltage arcing. DO NOT TRY TO DO THIS BY YOURSELF.

Best of luck my friend.

the colorwheel motor bearings are starting to go. you'll need to replace the colorwheel. you can get the part from a sharp service center and do it yourself or send it to one for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

I have sort of the same problem...there was a loud snap(kind of electical spark like) then the unit started humming loudly which changes sound as you move the unit around. The picture remains clear and the fan is quiet in shut down mode...still the wheel you think?

check the colour glass wheel is shattered with a piece of glass still stack to the wheel. it not even thats why it vibrates

The 23" CRT set may have a high voltage breakdown in the flyback transformer or focus divider. Take the back off and operate the set in a dark room. Look for anything that has a blue glow around it or sparks flying when the pop occurs. I won't guarantee this will find your problem, but it is definitive if you see these!

I once had a set with these symptoms. I stopped the blue glow and arcing by covering the focus divider with epoxy. It worked for a couple of months before the divider literally broke apart.

hi,

Please Check and service the fans and the Air filters. then check again. In case the noise still comes then service the fans or replace accordingly. By complete service of projector, this will work.

Hi, I'm not sure if it's the same problem I had..
I had it on picture mute, for maybe 15 mins, which may not have been a good idea. While it was muted, it made a sparking sound, and then a very loud grinding noise. When turned off, the lound noise stops, and the fan continues as usual for about a minute. As soon as it's turned back on, the grinding noise is back. But the logo seemed to display ok.

I took it in for repairs, and they said they needed to replace the color wheel to fix the problem.

Hi topher1234

I will need your Make and Model of the Projector , before I can do a diagnosis. Also include if this is a LCD or DLP machine.

Together with the above , can you feel any vibration on the Projector when you place your hand on it ?
