My truflat is speaking spanish on some channels and some channels showing picture and no sound . and the when i turn stereo,mono,and sap pops up.

You most likely have the SAP (Second Audio Program) feature enabled. Many shows do not have this sound track and that is when you hear nothing. When the SAP is on, it is usually in Spanish for English-speaking programs. Check your TV remote for SAP and see if you can disable it.

Its highly unlikely your TV is translating a broadcast signal. It is significantly more likely that the channel is a Spanish speaking channel

can no longer get on facebook has been spammed

Check your audio settings you are in SAP which means Special Aided programing, usually used for spanish speaking programing.

go to the menu and turn off the SAP, secondary audio program, this will solve the problem

you may be able to fix this problem by unplugging the power for about 10-15 min

You need to change the language settings on the TV menu, if you post the problem again, providing information on tv make and model we can be more specific, telling you exactly what to do.

YOUR POWER SUPPLY IS THE MAIN CAUSE OF THE PROBLEM,SO YOU MUST COLDSOLDER THE MAINBOARD OF YOUR TV,IF NOT WORKING REPLACE THE CPU.
