Screen distorts for a while then turns off


Your convergence chips likely failed and shorted out. This will cause many project TV sets to shut down to protect themselves from any damage. Take a look at this fixa page for more details or goto the site www.TvRepairKits.com for parts and instructions.

You can have a local tech bring out a crt tester and rejuvenate the tube for a temporary stay but it will eventually fail for good and in a short period of time it will be one or the other - - VERY expensive to repair or off to the dump...

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.

Tv turns off by it self


Ours 60" (60P8342) turns off after a short period of time also. My husband researched it online. The cheap solution he was told to try is to unplug the TV (or plug into power strip and switch off) when you are done watching it. A computer board inside over heats and it's a protection mechanism for it to turn off. Otherwise, it's over $100 to fix the computer board.
