Question about Samsung HL-T6187S Television
I have a DLP HL-T6187S Samsung that is nearly constantly displaying the volume bar AND dropping the volume to 0 if it isn't already. When the volume bar is displayed no other functions work, including powering off. I thought I read of similar problem and that it related to the side buttons , which I never use, so I attempted that suggested solution and disconnected the buttons from rest of board. Unfortunately this also disabled the remote, not just the side buttons. It is very random in occurence, and it is NOT a stray signal as the remote makes LEDs light up front but no lights when it randomly drops volume to 0.
If you can get at the controls again----undo or unsolder the micro switch for volume down! Remove it and see if set works.
A no brainer in that if that switch is bad and vol down still displays nothing else would work

Hey Devaman, like you I have just upgraded the software and disabled all of the timers, but most importantly I have disabled the "update whilst on stanby" option from the SETUP menu. It now seems to behave...
One more comment, I was very dishappointed by Samsung lack of interest, they never bothered to reply to my email, which I think is extremely rude... but then, am I surprised? :¬)

I had the same problem. I live in NJ and called the local authorized "service provide" listed on the Samsung website. What a joke. Quoted $350 just to show up, never showed up. So I opened my own TV. Took off the plastic back (10 screws) took off the large metal RF shield (12-14 screws) and noticed a blown component. The markings on the component were KL15L and it is apparently an NTC Thermistor. Obviously it got fried and not knowing if there was other damage I decided to set out to replace the entire Power PCB Board Assembly and not the component. There were two part numbers on the assembled board (BN97-00457E & BN94-00622E). After searching online I also found a suitable replacement number for these (BN96-04896A). I found two places who claimed to have the part or have it on order (shopjimmy.com and vancebaldwin.com). After placing orders with both and having neither come through, I broadened my search and found out that the LNR409D was basically the same model as my LNR408D so I looked for its Power PCB Board Assembly part number which turned out to be BN41-00521B. Google search for that part number showed the item available on ebay. I bought it a week ago (ebay 260311519904) for $144 plus $12 shipping. I removed the bad board an hour ago (6 screws about 7 connectors) installed the new one, plugged in the connectors, replaced the covers, plugged in the TV... AND IT WORKS!
Suggestion: If your TV is out of warranty then open it up (what have you got to lose) and see if the problem is obvious and maybe something you can fix (replace) yourself. The parts, spare boards, etc. are out there if you look.

THE PROBLEM IS Faulty parts on PS board , bad press for Samsung
Because the Samsung LNS4051D would not turn on and the power LED would blink 4 times and the relay would click and this would repeat again and again. I replaced power supply board parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors, three had their tops bulged up slightly that I missed on initial visual inspection. After seeing the reports of problems with these caps on http://www.fixya.com/support/t1336881-will_not_turn_or_off , I replaced them with Radio Shack part 272-1032, 1000 uf, 35v. They are slightly bigger, but fit OK. TV is working fine now. Cost was 4 x $1.59 = $6.36 plus the time. I saved between $100 to 300 in the process of either replacing the board or getting the unit serviced.

My samsung does the samething. TV is 3 yrs old. Repair guy said, it needs a new computer board. Said, that about 75% can be repaired if you can see what the problems is on the board. But the others show no sign so has to replace the whole board at $175.00 for the board and total cost around $300.00.
