Let verify first to narrow down to where the problem can be. First, attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.

    If it sounds normal through the RCA audio output, then you have problem in the power amp section, for most TV, you will need to replace the whole main board! unless you will want to pay a lot of money to troubleshoot down to component level. You may be better off using the RCA out and just turn off the internal speakers in the onscrenn audio setup. You also may be able to set the RCA out to be 'VARIABLE' instead of 'FIXED', this will aloow you to use the TV volume control to set the output level.

Sounds like a bad power inverter. You can easily purchase the part online and fix it yourself. Ebay sells plenty of them from prices ranging $15.00 and up.

Can't power on TV occasionally


It is possible that the conductivity of a power diode is diminished after a period of time causing the unit to receive just under the needed current to function. Test the resistance of internal components after periods of tine or seek manufactures assistance.

Sounds like you have some wiring issues. Did you recently install any new hardware into your car? If so, I would check all the wiring to make sure it is correct and that you are not shorting anything out. Also check all the fuses to make sure none are blown or need replacing.

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.
