The very first thing to check is to see if the TV backlights are cutting on and off as the tv restarts. If backlights constantly stay on during the rebooting process; then suspect a faulty Mainboard. If backlights cut off and on while tv is rebooting; then suspect a bad Power supply or bad bac...

    I don't buy TVs anymore, I used to, don't usually see freebies and they go fast. If I lived in a bigger city and had a large supply it would be profitable. There is SO much broken electronics everywhere, and me wants to fix. I've since started shocking myself with stereos, easier and I like the experience of 120 volts to the brain, those too had issues with broken solder on the chips, dried caps, abused... like TVs, no money in repair but you can usually get a service manual and they are not real complicated to fix. Most any solder repair nowadays will require hot air and a magnifying camera. Good repair equipment is SO expensive, even some of the stuff like those atlas testers are expensive.

      The cheaper ones like Hisense and TCL usually only have backlight issues. I got a Samsung yrs ago for 100, bad main, the board cost another 100 and took me yrs to find one. If I had good solder equipment I could repair main boards. Repair services are the way to make money, repairing main boards, but who has 2 grand for a rework machine?

I don't have the model number on hand but... It's a Samsung 55 that I found in the trash, the same symptom as this video. I opened it up and most of the LEDs were burnt out so I ordered new ones and replaced them, upon reassembly the panel slipped and I believe I damaged it... Now when it's turned on, it's all weird for a lack of better wording, believing I damaged the panel ribbon, is there a repair for this or is it basically a lost cause at this point? Our is there a source for a replacement that isn't more than a new tv unit lol
