Have TV Questions? Ask a TV Technician
Hello, Are you using some sort of a tuner/box between the aerial and the TV? Or is the only connection a direct aerial from the wall to the TV?
Have you tried rebooting the box itself by disconnecting it from power for 10 seconds and then plugging it back in please? If you're saying you're using a box between the incoming aerial and the TV then your most likely culprit is simply the box needs to be rebooted. Let me know.
Okay. We need to rule out whether the TV itself or the Sky Box is the root cause here.
So if you play a DVD on the set- is there STILL no sound (this tells us if the TV is actually the cause of the issue)?
As far a "fixing it"? There are no settings or adjustments on the TV, so if you've isolated it to the TV then this would mean the audio processing on the "Mainboard" has FAILED- requiring replacement of that board. There is no "Audio Reset", or "TV speakers ON/OFF" settings on this set...
It would be worth trying a hard reboot of the TV however.
Unplug the TV from power then press and hold the power button on the TV itself (not the remote) for 15 full seconds and release.
Wait a minute, plug the set back in and turn it on.
Check and see if there's sound and try those steps up to three times if the first do not work.
If you're still having the same problems. then the part that needs to be replaced is: 17MB65-2 23031698 HITACHI.
It is the board that all of the audio processing occurs on, and is a "plug and play" part (meaning no soldering or special tools are needed to replace it). I you're looking to fix the set yourself, you can purchase that part at the link below for your set:

Do you need further assistance with this?
Okay yes, that's correct. Now have you plugged it back in turned it on and checked for sound?
If there's still no sound, then the part that needs to be replaced is: 17MB65-2 23031698 HITACHI.
Other than that, I'm sorry for the bad news here and wish there were a quick fix.
That is DEFINITELY the problem. I've been repairing TV's from afar on here for close to 8 years now and that is always the cause of no sound- ALL of your audio is processed on that board.
As far as the part- I don't have your TV in front of me so I can only search using your MODEL NUMBER. I am also located in the US- so would not be privy to local sources of the part for you.
If you want to find the part elsewhere, and confirm- you will need to REMOVE THE ENTIRE back of your TV, find the board with the Scart and AV jacks on it- and write down the part number on the board itself then GOOGLE to search possible sources.
When I typed in your model number that eBay listing was the only one I found that showed your board.
You're welcome. If you need further assistance let me know. PLEASE DO click at least a 3 STAR RATING, at the top of the page for my efforts. That is how the site credits me for my work.
