    ==================================

    Thanks for model number info.

    Sounds Power Supply board in TV is defective. If you are comfortable with it then take off back cover of TV and follow AC power cord that will take you to power supply board, check its Fuse. If blew off, replace it and plug TV, if works then great and if fuse blow again, power supply board will be replaced.

    If you have no experience of TV repair or don't want to fix it yourself, please call local TV repair tech.
    Thanks.

    OK, do you get voltage on output connectors of power supply board if TV is plugged in AC?
    I would recommend to download service manual of this TV from Manual Zone for small fee that will help you in troubleshooting of No Power issue.
    Thanks.

    ==========================================

    No problem, I will wait your feedback.
    As I already recommended, download service manual copy from Manual Zone for small fee as service manual has troubleshooting guide, exploded views, schematics and part list info etc that will help you to locate problem section / board.
    It sounds that power supply board is bad and required replacement because you said you do not get output volts on power board.
    Thank you.

I have an hlp4663w 46in dlp samsung. The problem is after turning on the set it runs for a few minutes and I loose the picture, but I still have sound. I can turn it off and then back on and the picture...


It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

Bulb is only 2 mo. old. i have sound but no picture. red light is on. tv shuts itself off


step 1. Try pressing reset button. step 2 if step 1 does not work. Remove front cover and lamp door press, defeat the safety switch with a screw to hold the lamp door switch in and check to see if the lamp turns on. If it turns on for up to 10 sec then turns off replace thermal fuse.

I have the same tv with the same problem. Previously to resolve the issue I have left the system unplugged from the power overnight, however that did not fix my issue this time. Have you discovered a resolution to your problem yet?

SOUND NO PICTURE


I simply opened the TV set, and surprisingly found condensation on some of the electronic panels. I pulled out my blowdryer and aired them on low....reassembled the tv, and then turned it back on. Boy, was I surprised that it worked! That's how I got my picture back. Works fine now. Thanks.
