I bought a 61" January of 09. It was a 2008 so I got a decent sale price for it. It lasted 10 years of heavy use. It started failing about three years ago with the HDMI ports dyeing one by one until I got down to using component cables with an HDMI converter. The white dots started to show up and then the final nail in the coffin was the failure of the blue LED driver. I replaced it with a 75"-F1 VIZIO. I am happy with the color, size and brightness of the VIZIO over the old Sammy, but the Sammy handled motion better. I hope I get another 10 year out of the VIZIO (I think) but I doubt it.
I would like to thank everyone who participated in this thread I learned a lot over the years its been fun.

Dan: I sent money via paypal to the address you supplied some days ago. I haven't heard if you got it or not.

Thank you Larry. Yes I did. Also just responded to PM.

Everyone else, the carcass has been picked clean. Shell will head to the dump soon.

Just joined tonight 8/12/19 can anyone help with this. I have 2008 HL50650C replaced many parts over the years. Now I have the on/off problem. Checked power board all caps look fine, ordered another board and installed same problem. Powers up great picture and sound then powers off and on every 30 seconds or so. I do not have any blinking lights on power up green light. Can buy a main power board BP96-02054A at reasonable price anyone had any experience similar to my problem. Thanks, Mark

This thread is about the LED versions of Samsung DLP sets, and the "650" in your model number suggests to me that you have a model with a color wheel. Is that right?

For starters, I'm not familiar with the design of the color wheel version, but it does, indeed, sound like a power supply problem. Since there is no LED sub-SMPS, I'm supposing there's only one power board. Since you've replaced that already, I can't think of what might be the next likely culprit.

Do you have test equipment (voltmeter or scope) that you can monitor the various SMPS output voltages while the on/off cycling is occurring, to see if the voltages actually "go away", or dip down to a low value, or have a huge amount of ripple. This might suggest that something else is loading down the SMPS. Or something is causing the main processor to reset cyclically.

Don't think I can be more helpful than that, for now.
