TCL 48'' LE48FHDF3300ZTA, turns off by itself randomly

The tv works about some minutes an then just turns off by itself. Sometimes it's possible to turn it on again by pressing the power button, sometimes I have to disconnect it to make it work again.

Sounds like an over heating issue... might need to call the OEM

    Thanks for your answer. do you think it could be a damaged capacitor or something easy to repair? Or could it be something more difficult to diagnose/repair?

    could be the main board or the power supply. id have to take a look at it in person. most of these tv's anyone can fix if they know how. The real question is if its cost effective. it usually isnt.

SOURCE: Power turns off automatically

Same w/ mine.  Repairman said they turn off auto to protect the set no matter what is wrong.  Take it to be fixed.  Mine was right at $100.  Works great again.

SOURCE: TV Turns Off Automatically While Watching

Stop trying to turn on the set. You are causing more damage. The hissing sound you are hearing is either a High Voltage Transformer on the SMPS (Switched Mode Power Supply) indicating a short somewhere in the set or some capicitors that have shorted out. Also there can be a CRT that is leaking cooling fluid onto the Main bd or the Power/Deflection bd or both bds. Have a trained Samsung tech troubleshoot the set.

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..

Look for loose contacts in power outlet. Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.
