I can't believe how many tv's are breaking these days. I had a Philips 36" for 14 years and now my 2nd flat screen in in under 5 years has stopped working.
Anyway I have a Samsung P59D6500 and last week it went into standby by itself and wouldn't turn on so I unolugged it and plugged it back in and nothing so I unplugged it for 15-20 minutes and plugged it in and it turned on. This occured again 2 days later and the 3rd day it worked fine and the 4th day it was turning off every 30-45 minutes, sometimes the sound would be on, sometimes just standby. I'm thinking it has to be a heat issue so I set the picture to standard and it worked for the rest of the night about 20 deg. cooler than usual (I should point out the usual temp is around 120 in the top right corner). The next day it keeps shutting down with standard picture settings so I removed the back cover and can't see anything wrong, no blown fuses or bulging or leaking caps, solder joints and trace look good. Next I checked board temps with a infrared gauge and found 2 hot spots. 1 is on the smps (orange circle) and is 140-150deg. and the 2nd is on the Y-main (yellow circle) and is around 135deg. Next I unplugged tv for 20 min and plugged it back in and used a heat gun on the y-main to heat it to 160-170deg in small sections (hope this didn't cause more damage). After 8 min of doing this I didn't notice anything and stopped and the tv turned off 30 seconds later, sooner than usual. Repeated this on the smps and got the same result. Next day the tv turned on in the morning and went off after 15 min and would not come on again.
If I had the time I would learn and diagnose but I don't and other than Tom66's fast track manual I can't find any info on this model. If I had the money I would have it fixed by a not employed by Samsung repaiman because It don't like the idea of Samsung profiting from their lack of quality control. I would like to just replace just the damaged board or boards but I don't want to damage a new smps because of a bad X or Y-main. Any info or ideas would be appreciated.
