Question about Samsung HLN5065W 50" Rear Projection HDTV-Ready Television

1 Answer

Intermittent problem of no picture

My 3 year old 5065W will not show a picture at all. For a while, when I first turned the set on, sometimes I could hear the light engine trying to start the set up, but it would recycle and I would get no picture. Sometimes I could unplug the set and then plug back in and the problem would go away. This only happened every couple of months. Recently this happened and unplugging did not help. I used a dust blower to blow out the back of the set through the vents and the TV started working, but only for a couple of hours. When I turned it off, it would not start back up. Next, I took the back cover off and tried to clean off all the dust I could find. When I turned the set on, it worked. I watched TV for 2 hours with no problem. I turned the set off and on and it worked fine. But the next day, when I tried to turn it on I could not get a picture again. Now I am stuck. I had a technicial look at it and he said I need to replace the Light Engine which would be over $1500 except they do not make them for this set any longer. Samsung says they still make the components that make up the Light Engine but they would be more than $1500. Of course it is not worth nearly that to fix a 3 year old 50 DLP TV. Plus, I cannot believe it needs a new light engine when it was working intermittently. I believe my unplugging, dusting, cleaning worked because I have loose connection somewhere and must have reconnected it each time I was moving the set around. Where do I go from here? Anybody want to buy a used 5065W that won't work?

    Thank you for your suggestion, but help me understand the recommendation. The message you referred my to is below. On the message below, the answer was to replace the Luminance Chroama Sync Signal Processor. Do you think my problem is the same as this Sony pincushion problem? What do I replace on the Samsung?

    QUESTION NO. P710-9: Sony KP-53XBR45 projection TV picture had severe intermittent vertical pincushion symptoms. Pincushion problem stopped and picture now exhibits good convergence in center, bad convergence at perimeter. Straight vertical picture lines are displayed as wavy lines- horizontal scan lines look shifted relative to each other. Vertical compression, bottom 3" of picture missing. Fuses on convergence board OK. Have not replaced STK ICs yet.

    The vertical drive signal was incorrect. This signal originates on the M board from IC3005 (CXA1477AS), the Luminance/Chroma/Sync (Y/C/J ) Signal Processor. Replaced this part and set now works fine.

    Sorry, but this advice just doesn't help me. I have no clue how to use the Sony answer you forwarded. Does anyone else have any idea to help me with my problem? Thanks!

Tv is on with no picture or sound, only 4 months old!!

The power supply regulator board to your set has the fault. If you try to open the set, or try to repair it by yourself, the warranty will void. The set must have warranty as it is new. Why do you spend for it? Just contact the nearest authorised service center for Sceptre. the components in this set will be very hard to get from open electronic spare part market, and will costly too.

My Samsung HLN5065W started to freeze to a black and white

I have a problem with my HLN 5065W Samsung DLP that 3 other folks have and no solution. After the set is on from 5 minutes to 6 hours, the screen will freeze in black and white, I can turn it off for 5 minutes and it will display a good picture again. Sometimes the screen will just go dark blue, TV has to be cycled on/off to get the display back. This problem is getting worse, started as once a month, now 3-5 times a day. I have a tech background and can read a schematic, HELP.

Picture takes a while to come on

Replace the TV. The average lifespan of direct view CRT based TVs is 8-10 years. Take a leap into the 21st century and pick out a nice flat panel LCD. Take the old RCA attach a rope to it and bring it along on your next fishing trip and use it as an anchor.

Intermittent green tinted pictures (both indoors and outdoors)

The only recommendation is to correct the colour balance in a photo editor in your computer Come back here if you do not know about photo editing. As far as the camera is concerned there is no remedy as far as I can see -its old age time for a new one Repair is not an option.

Picture tube doesn't turn off

The power relay driver or the relay itself is bad. Its sticking closed so the voltage is there for the power supply but the micro has turned off the tuner.
