Hitachi tv sound is out

Switch off the TV at the wall plug and pull the plug out. Disconnect everything from the TV, wait 5 minutes, reconnect the aerial, put the wall plug back in and switch on. You should now have sound. I`ve had this on several occasions and this always solves the problem.

Chances are you have either a bad X SUS board, a bad Y-SUS board or bad Power Supply. In the worst case possibly all three.
I a very rare occasions I have seen the Plasma Panel cause on or more of the above boards to fail. The only way to find out is to call a professional to verify. I would not recommend going it alone.
I hope this helps,

sounds like loose solder or crt board...hard to say.

I have the exact set in the shop - same problem - but I have not gotten around to playing with it...

sounds like a possible flex module problem. repair is usually abut $500- $600.

i have the same problem, when i turn the volume knob on hitachi remote it goes away. Anyone heard of thi s???

ck all cables.

sounds like the vertical deflection is causing the CRTs to blank cause you still have sound and on screen displays. Try resoldering the vertical output IC see if that helps. If not you may need a new vertical output IC. Let me know if i can assist you further.

sounds like a problem or cold solder connections in the video section or b+ vlotage missing muting the video.

Could be a loose connection on the printed circuit board in the Vertical deflection circuit.
You would have to have a qualified technician to repair this problem.
A intermittent connection in the circuit described can cause a horizonal line across the screen.
You have to be careful and not leave the TV on for a period of time with a bright line, as it can actually burn a line on the CRT screens, which is permanent.

May have a CRT going south on you. This is actually a more common problem than once thought...accordianman
