I have an Insignia ns-p501q-10a 50 inch plasma that began cycling on and off last night.
I am considering having someone repair it, but if I can troubleshoot the problem on my own, I might as well do it myself.
I took the back panel off to try to see if cleaning the fan would help it. It didn't. There is no fan to clean.
I did see a whisker that may have shorted out a capacitor; however, clearing out that dust did not solve the problem. I didn't check the fuse on the power supply. Right now, I don't suspect the fuse.
When I plug the TV in, it automatically begins to cycle. I can hear one solid relay firing followed by a few taps. Shortly after that, the relay fires again, turning the TV off.
During this time, the power LED on the from of the TV turns solid, then blinks. I don't know if this is a diagnostic code or if it's just a symptom.
I didn't see or smell any smoke when this started to happen. Also, the capacitors didn't appear severely deformed. I will have to take a look at them later.
What can I do to ensure that the PS is faulty? If a bad capacitor is the culprit, is it worth replacing vs the whole board? I haven't soldered in 15 years and never really was great at it.
