Samsung QN55LS03 | The Frame TV | Weird power cycle and restart problem
First thread here on this forum, excuse me if I miss something in my first post.
I have the 55” variant of the Frame TV which is essentially a QLED tv. There's a weird problem where it would keep on restarting on its own. Funny thing is it might work perfectly for couple of days and then decides to go down the restart route. A few pointers:
1. If I let the TV sit idle for a day, for the very first time it boots after that time period it usually keeps working for 5 minutes before restarting. After that it restarts every 5 seconds.
2. I've tried the tape method and seem to find a pin where I can see the picture (although with frame skips, vertical lines and what not) and the TV doesn't restart. It's the VGHD panel pin.
3. Since I've tried the tape method, that also implies I've eliminated other potential causes. Basically if I remove the display connector, there's sound and no restarting.
4. If the panel is faulty, why don't I see any dead pixels or horizontal/vertical lines when the TV is working properly?
I do have the service manual with me but not able to decode which pins should I try masking for a stable picture. I don't mind even if I end up with a dead pixel row. Any sort of help would be appreciated.
