Question about Samsung HLR5667W 56" Rear Projection HDTV

1 Answer

Tv will not stay on for more than about 5 seconds

When i plug the power cord in, the tv automatically turns on. i dont have to press power or anything, it just turns on, makes the normal beeping noise that its turning on, the lamp light flashes a couple times, the picture comes on, works for about 3 seconds, then the screen freezes, stays frozen for a couple more seconds and then the tv shuts off, restarts and does the whole sequence over again. what could be causing this? i dont think its the bulb as the picture is very clear and bright when its on, but the tv will not stay on. the other thing that i noticed it is doing is throughout the whole process, anytime i press any button on the remote other than menu, the (TIMER) light on the power button lights up. any insight into this would be greatly appricated. thanks

    I don't even get 5 sec. Samsung HL-R5667W turning set on results in brief flash from "tiner" lamp followed by several flashes from "lamp" light then nothing. No picture or sound at any time.

    Same problem. We have had the set for about 2 years. The service guy said he thinks the board is bad and lightning may have struck. We are in Florida and have lightning all the time. I think it is a deffect after reading several post. $500 to $600 job. I will keep you informed.

It is normal for timer lite to blink when a remote command is sent. However, the problem you are having can be caused by several different things. I have had the same problem with my samsung dlp and have done the factory service for several years. First, you need to vacuum out all vent holes on the rear of the set. Then, remove the lamp cover, unscrew the screw holding the lamp in place and remove lamp. Do not touch glass. Look to see if filament is shattered. If not, firmly reinstall lamp and secure. Then reinstall lamp door making sure you engage door switch. Try set and see if this helps unless lamp was shattered. If not, replace lamp. Weather or not it is bad, you will need one sooner or later. Also, listen for a zing noise a few seconds after power is engaged. This is the color wheel which is another possible cause for this symptom. Truth is, almost any part in the set can cause this, but I gave you the most common things you can do by yourself to test this unit. Good luck, Russmann.

Panasonic pt-53wX42, power wont stay on. Turn on, no picture then it will turn off by itself after 5 seconds. The red power button will flash on and off until I unplug unit and start the whole process...


I'm no expert, but I'd start by taking a "VERY GOOD LOOK" w/magnifing glass if possible , @ UR Wall Outlet Power Cord. Change to different wall outlet. Ur Power Cord "should" just pull right out of the back of your TV. If nothing in those places, then take off back panel (or part where power cord plugs into TV & AGAIN inspect area around where power cord attached for, yeah, that's right, the dreaded black area around plug-in area. Maybe it's just a bent prong. Any other funny things going on that U didn't mention here? Good Luck Leonard aka quikstudy@cox.net

TV turns off


It sounds like you might either have a bad power cord or you might have an over heating issue. Some times the TV will automatically shut off if it senses a fan issue or it starts to overheat. What technology is your set? DLP, LCOS, DILA...? If its under warranty I'd suggest to get someone out asap to take a look at it.
