Where are you from? Without knowing it, how can one point out the authorized service center for Hyundai, near you?

Hyundai... | Answered on Oct 30, 2013


You have a failed sustain board (probably YSUS) and/or failed buffer board.

I don't know where you are, but here in the States this TV is not popular at all and I can't help you better without having you pull out the YSUS board and seeing its model number. Should start with LJ92 or LJ44.

Here's a quick guide on what are you looking for:

The picture is just a guide...your TV will look slightly different, but the essential components will still be there at the same places and still do the same functions, only they'll look different.

Hope this helps.

Better get assistance from the authorized service center. Before that, check whether you have pressed the mute switch!

Hello,

Yes I had the same problem, but mine was also video too.
I have worked on these tvs before and found the problem is with the CPU card.
You will need to have fixed or replaced.

Good luck
