No sound I have no sound . I used to be able to turn it off and than back on again but it doesn't work anymore. I purchased this new in 2001 and had to replace the sound panel twice. This costs around $400 to $500 to fix. Not happy. Is there a way around this problem ???

Re: no sound

Now this is very interesting you replaced the sound module twice well this is not good, however this does denote an engineering flaw in that module. I am almost afraid of telling you what you have to do and that is fix the module, which requires you to: 1) Have knowledge of electronics 2) Have the proper equipment 3) have a schematic to aid in troubleshooting this issue 4) be prepared to engineer a way of limiting the current in that module so that it does not go out as fast. Those are the facts, television repair is a vocation, something that someone trains to do over the course of years (3-4 years). I have offered advice on this forum and been told it was not helpful when shown to other techs I know they say that the advice I gave was sound but it was not what the person wanted to hear. You have already spent $400.00 to $500.00 dollars on this set and you don't want to spend anymore, well I have bad news even if you do it yourself you are going to end up spending 200 - 400 on this set depending on the cost of the module, and guess what, it is going to go out again, why because you have to find out what is happening to that module and then find a way of preventing it. I can tell you what is causing your problem and that is heat, how do you prevent heat? use a heatsink with a proper amount of heat sink paste. Can I help you fix this module (which will cut your cost) yes I can, if I were local to you I would ask you to bring your set over and we would begin to work on it, The problem is I might not be in your state and you have already invested money in this system, which has to be reengineered to repair the sound module problem. In other words, ther is no logical way around this problem, except to repair the module which will still cost you money.

Sound doesn't work in HDMI mode, just picture. I tried buying a new HDMI cord but that didn't work either. Then one night the TV just turned off and now it won't turn back on.

Likely not related but HDMI does not like being connected if either unit is plugged in or powered up.

As to the TV let me know the brand and model number and what if any lights at all come on when you plug it in etc.

Cant get our HDMI to work on our JVC HD 58S998.

First, contrary to popular opinion, HDMI cables connect to a tv are not the best way to connect the two. The HDMI technology has flaws that often shows up as sound problems.

If your TV has the capability for component connections, use them. It will take 5 cables, 3 for video and 2 for audio. You will get superior sound and video. The 5 cables terminate in RCA type connectors and are much cheaper than an HDMI cable.

I hope this helps and solves your problem. :-)

TV turns on for about 10-15 min then turns off

Sounds like a tuner section problem. When you are playing a DVD. You are only using the audio video circuit of the TV. Something like a monitor. But when you go back to TV mode... You are now in the tv tuner circuit. And your problem lays there. I had a mouse **** on my tuner section of my tv and it caused the same problem. Yes mice do ****...
