Hi


Thanks for using FixYa. To reset it leave the unit unplugged for 4-24hrs however, from what you have described it seems that you might have a backlight and/or an inverter board issue with this TV set. It could also be due to the inverter circuits for the backlights. The inverter is the power supply source for the backlights. There could also be a screen driver problem; if it is then you have to change the entire inverter board. All this is only recommended if you have some kind of expertise for checking the internal circuitry of the TV as these units have high voltages running even when the set is switched off. The cost to change the inverter board including labor would be around $250, if you get this done by a professional. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

LNT4661F tv black shadow on left won't go away been told its the back panel does this make sense?


Hi most likely yes it is your panel. However there is a chance that it could be your t-con board. I would say 80% Panel 20% chance that it might be your t-con board. The T-con board is fairly inexpensive compare to teh screen so I would give it a try first.

My samsung LCD LNS4692D has picture for 2 to 5 seconds only after turning it goes out. audio remains on. picture quality is good. is it the T-con?


0ne of 3 has failed:
(in order of probability):

1. Backlight inverter
2. Power Supply
3. Backlight

More specifically on #1 and #2 - capacitors either bulging, leaking, or exploded.

Please seek the expertise of an experienced TV repair technician - as they contain potentially lethal voltages that must be properly discharged before work can begin.

Thanks!

My samsung 1080p t.v. will not stop turning on and off. I can't even get a picture, it just keeps shutting on and off. I had to unplug it. Any suggestions?


First, you probably have a bad Power Supply. Second, the Main bd can also cause this problem. Have a trained Samsung tech troubleshoot the set.
