Question about Samsung LTP326WX/XAA 32 in. HD-Ready LCD Television
Melody does not play when set turns off and on by itself, other problem is the screen shows halve a picture right side no picture left side shows picture its split in the middle left no picture right side picture. Now what I did when the screen is showing grainy as if dnle is off with normal colors you can do a demo in the picture set up screen basically its as if the dnle is on even though it was off in settings its on but with out the demo tags on the screen I can restore picture grayness by turning dnle off and on and if i press source when the screen halve is black it comes back normal but screen gets halve black again. When its hooked to cable sound goes of and comes back on and is losing tuner lock and displays ch 17 even though tv is on ch 3 . Tv is turning itself off picture goes dark and sound goes off and I hear the relay click and then after a cuple of seconds turns back on. When video input is being used the set turns on and off and if cable is connected directly to tv coax jack the tv sound after turning on and off eventually the sound goes out and will come back if set is powered down and turned back on. Voltage on cnb811 is 8.35v when set is on when off 8.80v reading from the redwire off powersupply and white wire reading off power supply is 00.3v dc when tv is off when on its 3.30v dc and so far tv turned itself off and on 10-15 times this happened only 1 time when set turns itself off and on white wire voltage goes from 3.30v to 00.3 then goes back to 3.30 when set has a picture.
I had a similar problem where my 61" Samsung DLP was turning itself off very frequently I had resolved to try replacing the bulb. I called a local TV repair place to see if they had my buld in stock. The guy I spoke to actually told me how to fix my problem! There is a little blue switch behind the bulb access door. The inside of the door has a little piece that presses the switch down. The switch is supposed to work correctly weather the switch is in the up or down position but samsung forgot to take expansion from heat into account. If the switch is held in the upper position by the door and the plastic expands to a certain point, it triggers the set to shut off. This does not occur of the switch is held in the lower position. What you need to do is take the access door off and put it back on by sliding it into position from above. That will hold the switch in the down position, eliminating the problem. My set has not **** itself off ever since.

I have the same problem of the set turning off and on by itself. There is a circuit in Samsung TVs that would shut it down if a very loud noise occurs in the program being watched, but I have not noticed that correlation. My problem is solved by vacuuming the back panels of the set. They do not seem to have any significant dust on them, but I think the vacuum sucks somewhat inside of the TV and does some good with the fan that is supposed to be cooling the bulb and the mirror. It seems to work for months on end and when the problem recurrs, I vacuum again.

My Samsung HLS5687W was turning off, sometimes every 10 minutes, and sometimes it would go for hours without a problem. I noticed it turned off more frequently when it was cold. There is a blue switch inside the bulb access door that needs to stay down that can trigger when the back panel expands and contracts with temperature changes. Vacuum the back, take off the bulb access door, replace from top to bottom and tighten. For extra measure I placed a small fan behind the tv and haven't had a problem since.

I had the same problem. TV turning off by itself. called stupid samsung and they said 100% its the bulb. I ordered a bulb and it didn't fix the problem. I called a local repair man and he said sounds like a heating problem. I recently ordered a new fan so i'll let you know if it works.....

I HAVE A HLS 5679W, HAD IT FOR LESS THAN A YEAR, AND IT KEEPS TURNING OFF AND ON WITH CLICKING SOUND. It takes about 10 or so cycles before the tv turns on and works. Sometimes with no sound
