Pioneer SDM1407 Rear Projection Monitor System (TV) 42"
When I turn on the TV it has like a popping sound, normally this goes away and the TV operates fine. It has been without sound for the last day and just hisses quietly? What should I do, we are vacuuming behind the back to see if this will make a difference but I think it is not good. Your advice would be welcome?
Kind regards
Tina
What happened was we called in a technician, and he replaced the little sound thingey which had burnt out. He was really surprised that our TV hadn't blown up? It's working a dream now - like brand new.

You have to get in the Audio Menu and tell the TV "What You Want". Things are now set-up to operate with an external sound system. You have to set things back to Normal or Default.
It can be a couple things. Something bad on the power board. Or the vertical output circuit. How long ago did you purchase the television. Your best course of action is to have it serviced. If you need any information or other assistance let me know. Thanks, Lee
It is most likely the power supply. Do not try to fix this yourself. There are LETHAL voltages inside such a TV, which can persist for WEEKS after it has been turned off.
I had the same problem, try running the TV on Mute, if it is a bad solder joint the sound can vibrate the solder point and trip the relay, if the TV doesn't trip off with the sound on mute then it is probably the big power transformer's solder connection needs resoldered. sound vibration from those big pioneer speakers may loosen the solder joint over a period of time because the transformer is heavier and bulky and vibrates a lot.
as far as it turning off on its own I would get a fan on it and see if that make a difference make sure that the fan is able to flow around the tv especially through the back of it, if this stops it from turning off then it is an overheating problem
Pictures great but definately no sound?
