Projection TV`s have many protective circuits in them, they protect your CRT`s from damage, over voltage called x-ray, and many others, you need to have it checked before the damage is more costly your TV is not happy and needs to be checked

Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

Look for a button on the TV that says 'source'. Push it and wait for a few seconds, if the picture does not come back, push it again and wait a few more seconds. Do this until you have cycled through all of the input sources for your TV.

Speakers on my Pioneer VSX-D466S receiver are not working. Is there an internal fuse that may be blown?


some recievers have a monitor button on them. if it gets pushed your sound wont work. look at the display and see if you see the work monitor. if so you should have a monitor button either on the reciever or the remote. it is a toggle button so just push it till it goes away and sound comes back on. make sure to turn sound back down before pushing this button as you might have turned the volume way up trying to hear it. my wife accidentally pushed it last week and she thougt is was broken untill i got home and simply pushed the button.

Sporadic Hum on HLP4663W


I would guess that its the fan for the lamp, as the color wheel will power down as soon as the power is cut. the cooling fans will continue to run

My Sony tv CRT


If it's between 5-10 secs, that's normal. You will turn the tv on and hear a loud (buzz/hum) that is the picture tube firing up, once it's fired up, it has a few more seconds until your picture comes up fully. That is about 5-10 secs from pushing the power button.

If it's taking longer than that, your picture tube may be going out.

I had a 36XBR250 and it took about 10 secs to fire up and show a picture, and it was 5 1/2 years old.

No picture, hear sound, television will shut off after a few seconds.


Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.
