Question about Samsung HLP5085W 50" Rear Projection HDTV-Ready Television

1 Answer

No picture w/sound and controls on front panel don't responed

The picture went out but the sound still worked and when I tried to turn the set off with the remote and front panel controls there was no response and then the signal showing a lamp failure appeared, had to unplug to turn power off. I replaced the lamp and still the same thing. Had a technician look at it and was informed the color wheel, fans, ballast and lamp check good, he thinks it might be the digital board.

Any ideas before I put too much money into this thing.

    When I went to the Samsung web site for parts, I couldn't find the digital board. I found the dmd board but no other board P/N, is there a different name for it? Also, is this something I could replace or am I better off leaving it to the technician? I do know how to solder and have messed with computers.

The technician you saw was correct, most likly it wasnt the lamp by istelf something in the circuit board caused the lamp to go out, you only replaced what was the results of what went wrong.

    youd be better off having a technician do it so that you have some sort of warranty for their work done. Plus the Tech will be able to diagnose any other problems.

Why won't big oven door unlatch?

sounds like the lock motor has failed. Lots of clicking noises and not being able to lock/unlock is normally a good indicator. In some rare circumstances, main control board could be faulty. Look for me on 6ya if you need any more detailed help.

Siren is going off and I don't know how to stop it. It was installed about 9 years ago and installer went out of business. I think it is wired separately from the security panel. We are clear across...

Time to install another alarm system.Go to the power source just disconnect the battery power source,if the control panel don't acept the codes or respone to the codes anymore.If the alarm keep going off the police come out more than one,they'll give a ticket every other times they have to show up to check around.

The fault may be on the control board. Sometimes the button switches can be stuck, or there may be something causing some conduction on the control circuit board. It is also possible to have a component failure that is causing a continuous command to keep the volume to the high position.

Something that causes failures of controls in TV sets is when people clean the screen, they spray liquid cleaner on the screen. Some of it drips down in to the controls and on to the circuit board. This will usually cause damage, and thus the set will require shop service.

Turns on But No Picture and No Sound

sounds like it could be a cabling issue, try replacing the cabling (if you have another tv, you can borrow the cabling before purchasing new set of cabling)

LG LST-5100P set top box. Several times a day have

cap-grant, my friend has the same problem with set top box. When I phone maker I was told it is due to poor and weak signal. You must have 80% signal strength to maintain good picture. When signal strength dropped picture would freeze and had to be turned off at the power point to restart as nothing would work. So I guess what my experience says is you may need better aerial to boost signal and prevent dropout Leonard210
