I'm with you on this one.....
I think I have the answer though.
I have an HL72A650 and we were smelling something burning the other night. Then the TV started to click on and off just as the OP's set was doing.
I took the back panel off and there was brown slime running down the power board. It looks like one of the capacitors blew.
The board that is in my set currently isower supply MODEL NO: PN082DPS-VF CODE NO: BP44-01002A INPUT VOLTAGE: 100-120V 50/60Hz, 6.3A REV. 1.3
I think there is a new one out BP44-01002C
Hope this helps....
Been having some issues with my Samsung. The lamp went out recently and I just replaced it with a new one and its only been 5 days and a new issue has surfaced. The TV will power up and the picture will be great, then it suddenly shuts off, makes a buzzing noise and starts to boot back up. After a few moments, the picture returns. That happened once last night and today, my girlfriend noticed it happened 3 times earlier in a span of 30 minutes. This was at 10am pacific. The TV was off until 5pm today and since then, no shut downs. Any one have an idea what the issue is? I have a hunch that its either the power supply or the ballast. I can replace the ballast, but not sure how much the power supply is or where I can get one. I would rather spend as little to repair it myself than paying a repair tech to tell me what it is and charge extra to install. Any help is greatly appreciated.
You need to look in the 2008 Samsung HLxxA650 Owners thread and
you'll find some answers
I think the reason people don't respond to questions much is because when they do,vno one thanks them. The OP just take the knowledge and runs.
I tried to help 9 months ago with part numbers et and no one thanked me....
I am having the exact same issues with my HL61A650, I power it on then after about 1 minute the set turns off with a buzzing noise then boots back up. I took off the back cover and noticed that the buzzing noise is coming from the starter on the ballast board, so I replaced it with a new OEM ballast, and I am still having the same problem. I am about to order a new power supply, but I was just curious if anyone has changed their power supply with this same problem and had any luck. Sorry for bumping an old thread, It was the first one that I found that had the exact symtoms and model tv that I have. Thank you in advance to anyone that can help me with some info.
I too am having this same problem, did you ever get it fixed? Sorry to bumb this thread again. I know they are recalling some TV's for something but this model isnt in the mix.
Any Help from anyone would be great!
i unplugged, and plugged after a day, and tv is turned on (no pictures) without pressing any remote buttons, and same thing.
would really appreciate any HELP
I think this may be related to "lamp overheat protection"... I notice there didn't seem to be much air flow from the back of the TV so I put a small fan on the back forcing a lot of air into the lamp compartment and the problem seems to go away... When I turn the fan off, the TV reset 5 times in 30 minutes.... I am wondering if the fan is getting weak and the RPM is not to spec.
It could also be related to the thermal expansion of some component on a circuit board such as the power supply.
Mrfixer81, did you replace the power supply? and did that fix it for you?
My tv used to turn off and not come back on until I kept pressing on several times up to a half an hour sometimes I would give up. I have Comcast and was having problems with another tv and tech from the office came out and said outside wiring was messed up and rewired it 2 weeks ago and it hasn't happened since. One of my lamps went out a few days before that and now am trying to find a parts place for that. It's a 2008 or 2009 model.
