Check your power supply board for some bad caps (capacitors) on the board. They will look bulged on the top an may be a little leaky (brownish stain). A bad cap can sometimes produce a harmonic, causing issue's with the sound. Also look at the signal board (where all the inputs are), for bad caps. I have come across this on a lcd tv!! Good luck, hope this is helpful!

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.

I have checked cables and different methods of connecting, but the white and red audio out of my PVR appear to have stopped putting out sound.


Go through the setup of the PVR and check the sound settings. It sounds like it's only producing digital audio, that's why it works with HDMI but you want analog, so set the audio to stereo, or try every setting to see what works!

Hi, the sound on my Hitachi switches off after midnight every night. I can get it back briefly if I switch it off/on then it goes again? Daytime it's ok & the Pic is fine! Any ideas?


I would go into Setup and timer/ clock. The sound might well be in off position. You should be able to change the clock to your eeds. Kolbrun
