Top 10 Samsung HLR5067WX 50" Rear Projection HDTV Questions & Answers

Hello,
I stumbled across this web page and am hoping it will help solve some of my questions. I just had this TV sent from overseas from the US to Germany where I am stationed. Upon arrival it does not turn on. When I hit the power button the light turns green, and then turns off and the STD BY / LAMP LED goes flashing red. I removed the back cover to see if I could see anything happening, and it appears that the light turns on very briefly, and then turns off. I have never worked on a DLP TV, and have no idea where a good place to start is. I would think the bulb is fine if it powers up. I removed the light and reseated about 3-4 connections with no improvements. I am somewhat electronically competent and should be able to gain access to multimeters and any other instruments i might need. I was wondering if there is an easy way to test the ballast, or would it be ok as well if it was able to power on the bulb even tho brief. If not the ballast, are any of these symptoms pointing towards the DMD board? If you have any sugjestions, it would be much appreciated. Thanks

Dear Sir

I have a Samsung 50" DLP Model HL-R5076W (model code HLR5067WAX/XAA) type number AT50L6 made in August 2005 (bought new) its worked fine until recently when it started to have these symptoms...

On an analog input (DVD connected to component input) it came on with non-moving plaid-like pattern of lines, the picture was mostly green (with some blue/purple tints) and slow moving.. i.e. maybe only about 1/4 normal frame rate, until finally the picture would lock up and then the sets controls would lock up (non responsive to physical buttons on the set OR remote control input, although the remote indicator lamp will flash on the set when you press a remote button). Had to unplug/replug to reset the set.

Comes back on, didn't have the problem immediately but then it came back after a few minutes. By plugging/unplugging I was able to determine that it only does this on analog inputs, digital inputs (HDMI, PC/VGA and AIR- with a HD signal) all work fine.

Also... if displaying an analog signal WITH the plaid pattern, if I turn on the TV's menu or the TV-GUIDE that content displays just fine (over top of or including PIP with bad plaid but main display ok).

The problem has become steadily worse to the point that now its not doing the green plaid lines, but locking up and going to a blank screen very rapidly... now does this on digital inputs sometimes too.

I am an electrical engineer and purchased the service manual, and I believe the problem to be the "analog board" since it seems to process all analog signals before handing off to the digital board AND because it processes all controls (physical buttons on the set and remote control) plus the power supply routes through this board to other circuits within the set.

I know the lamp/balast are ok, color wheel is spinning and the DMD/Light Engine must be ok since it can display the TV's menus and TV-GUIDE just fine. Equally the power supply itself must be ok since things are working normally.

In your opinion am I on the right track? do you think replacing the analog board (bought from samsungparts.com) would be my best option?

there is a loud buzzing noise coming from samsung 50 projection tv

Is this something a novice can do? Or is this better left for the pros?
I did do my own bulb replacement - piece of cake. Now my repair guy is suggesting that I need to replace this part.bp94-02084a
#1 - i don't want to shell out $600 for him to fix it.
#2- i am not crazy about paying $400 for the part, but if I can save on the labor, it would hurt less.
#3 - I am in the digital signage business and want to beat up my Samsung rep!!

I have a Samsung HLR5067WX 50" DLP HDTV that is 3 years old. For the past two days, my tv has been humming everytime it is turned on and then stops when it is turned off. The DLP lamp has been replaced about a year ago and besides the humming noise, there is nothing wrong with the tv. The HD picture, sound and everything else works perfectly fine. Please help so I don't have to keep turning my tv up to 10 to drown out the humming noise.

 television shuts itself off. sometimes runs ok for a couple days, then shuts self off. sometimes will shut off 5 to 10 times within a half hour. my model # HLS5086WX/XAA, 50 inch rear projection high def.

I am also experiencing green pl;aid lines throughout on all channels except HD channels. HD channels come in clear. Unplug reset for the day and up until recently worked. Set did have to warm up period but green plaid lines dissapeared and all channels were clear. Now even after reset only HD channels are clear. I am leaning toward the analog board, Also red temp light stays on. Any solutions?

Loud noise coming from back non stop, picture is there but not clear as far colors and stability, noise doesn't stop until I turn off TV and goes away within seconds, and comes on when TV on, noise so loud that I cant hear the show but the picture is not clear anyway. Please any idea that will help me solve this problem.

I have a Samsung HLR5067W that had a busted color wheel. I just replaced the color wheel and the tv sounds 100 times better, but still does teh same thing. By that I mean the LAMP light blinks until the STANDBY light comes on for 2 seconds then it repeats that process 2 more times before all 3 lights (LAMP, STANDBY, TEMP) on the front blink simultaneously. I checked the back of the unit when trying to power on and the lamp never lights up. I want to go ahead and replace the ballast, because it sounds like the problem. Can anyone confirm this solution? Thanks

I have a Samsung HLR5067WAX/XAA 56 inch, rear projection. Replaced lamp on it two years ago, was working fine. This morning a sudden thunderstorm blew in. When the power came back on, the cable picture looks kile green and pink plaid. The TV Guide Screen came in fine. After unplugging the set and letting it sit, I plugged it back in, the cable and DVD picture still scrambled, and it started to make a high pitched whine. Had to unplug TV from wall because the Off button would not work. What can I do to fix this?
