Question about Projection Televisions

Open Question

Turned on my Westinghouse SK42H330s - no sound. Picture fine - everything else worked - no sound. Checked all my settings - and yes, the vol. was up and not on mute. I finally unplugged it and when it came back on - the audio was fine. Tell me what happened please. What's going on?

    Except that my Westinghouse SK42H330s simply stopped sounding. It was on and playing fine, then suddenly stopped making any sound. The picture is fine. I unplugged it, waited about a minute, but the audio has not returned. Anyone know how to fix this barring a trip to the repair shop.

SOURCE: no picture but has sound

If the screen turns bright blue then you may have a bad blue crt(picture tube) I suggest an on site diagnosis by a Sony ASC to verify if it's the crt. Crt's can run up to $150.00 plus installatin and alignments.

the lamp has a life cicle. if yours is been used a lot. then the lamp has to be changed. when the tv cannot turn on steady and gets off imm. the computer inside the tv tries to turn off the set but the lamp charges again and the micro tends to keep working. the first step to take in this tv is to change the lamp to eliminate this common source of problems

SOURCE: no picture

If i am to understand this correctly, this is a rear projection television. Inside there may be 1 - 3 " color " control boards that control the picture before going on to the projector. an accumulation of dust / dirt / debris has adverse affects on electronic componants, make sure they are dust free (compressed air cleans them off quite well. If using a home compressor, make sure there is a vapor filter to remove water from the airlines.)

If they are clean, and as you said you recently had the television serviced to replace the projection lamp, take the television back to the repair shop to have them determine the problem.

If you yourself replaced the projection lamp, be sure to check all connections are properly seated if you had to disconnect something, make sure they are in the proper places, and any connections are securely connected.

If all else fails, have a local electronics / television repair person check the unit for faulty componants.

SOURCE: FINAL WARNING REPLACE LAMP NOW

All rear projection TVs has a lamp thats like a special bulb inside the TV.

The TV is warning you that this is about to go and will need to be replaced.

This is not a serious problem as TV lamps goes after certains hours of use (normally 4,000 hours sometimes more) and the TV manual should have instructions on how to do this and the part you need.

Contact Sharp support if your TV is still in warranty and for further help :

MITSUBISHI WS55907 Diamond 1080 TV bought in 2000 was powered off, unplugged, for a year. Turned the set on with remote last night and worked fine, had very crisp picture.


Your TV was waiting between 2000 and now to suffer power supply failure. It is very frustrating to go from everything working perfectly to nothing.

NO SOUND at all!


The audio is controlled by the small signal board, which is very costly and hard to get, however I will post a link where you can get one for about half price. Its called the ITC small signal board and its actually a sale item at this site. Heres the link.

No picture just sound


Your projection tubes are messed up. It's a very expensive fix, just get a working TV off craigslist with a smashed screen and reuse your screen itself (usually 100-200$) or just toss the TV and upgrade to an LCD

I have a philips Matchline tv (29pt6361/79r) the tv works fine except it automatically turns the volume down without any buttons on the remote or tv being pushed


well depends on how far it turns the volume down as to what the cause is and if the volume bar on screen display comes on when the vol. goes down. if it just goes down a little you probably have the "smart sound" setting turned on in the audio menu turn it off and see if prob. goes away. if the vol. bar comes on the screen whenever the vol. goes down the you most likely have a bad button on your front panel and it doesn't have to be the vol. down button. it you think it is the button it would need solder work to be changed most likely shop job.
