Question about Samsung Televison & Video

1 Answer

After I have been watching my ln-t4081f for a while and I turn it off, when I turn it back on again all I get are lines on the screen and no picture. I have to let it "rest" for quite some time before it operates properly.

You can also try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..

Samsung LN-T4081F Television just stopped working. No picture but TV TURNS ON.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.
