My WD 57733 will attempt to power up (almost like a whistling sound as it attempt to power up) then will power back down.

When was the last time you replaced the lamp? That sort of sounds like the ballast is unhappy with a bad lamp. The 57733 is a good TV. The other possibility is a stuck/dirty color wheel.

Check the lamp and see if it looks worn out(dark or grey in the tube down the center). Also make sure its either a Philips brand or Osram brand.

Let me know and Ill see what I can recommend next

Can dust build up on a picture tube's circuit board cause them to overheat and shut the tv down.

dust will not cause an issue like this in this type of set--RCA? it means a short of some type exists and the set shuts down or blanks the tubes--all you have described as far as appearance is normal.

RCA sets like this can be difficult to repair and also if you Google the model number you will see they have a lot of "problems".

My infocus IN1 projector won't turn on anymore.

It may be the lamp is out. Normally a projector will try & fire the lamp 3-5 times then shut down with a different color light like amber or red. If the lamp doesn't light then it could be the lamp or perhaps the lamp ballast that starts the lamp has failed. A stuck fan also causes similar symptoms. There's 2-4 fans in the projector if one is stuck or bad it will turn off within 5 seconds or so after the lamp lights.
Does your lamp light at all? Are the lights a different color after it shuts down? Answers to these questions help figure out what's wrong though it's impossible to say for sure without looking at it. I service almost all Infocus projectors if you would like a quote please reply with your email address or write me at
Good Luck,

Samsung HC-P4752W power and/or convergence problems

Sounds like you soldered two of the convergence pins together by accident. If its shorted the TV will shut down.

I hope you can help me.. I own a Samsung DLP TV model no. HL56A650C1F, 56". The problem I am having is that it just turns off by itself and lights "stand by" and "lamp" are flashing at same time.Sometimes, when I'm trying to turn it on- it shuts off by it self.

When the power button the red button flashes but nothing else hap

the red light flashing means the set is in auto shut down, could be a power supply problem or a convergence IC problem. tech should first check all diodes and caps in power supply then replace convergence IC's

Power turns off after a couple seconds

I do not have an answer butthis is happening to me now and read where it happened to another Mitsu.TV owner. they should be made to fix it because this looks like an equal to an auto recall.
