I have a 50 inch theatre view tv I bought 7 years ago. The sound is going on it. It is very quient and muffles sounding. Can I fix this myself? Thanks for your help. Looking forward to your answer. Julie

Go back to Walmart this must be a warranty issue.

i bought mine in january 2011 and just started having the same problem. i have to turn the head unit off and back on again to get sound back. any fixes for this yet?

I have the sames t.v you have to go in the back flip the power cord switch...then reboot the t.v.

run all of your components through the stereo first and just bring the video out of the home theater
thanks

Hav 50 inch lg no pic but got sound wtf how do i fix it an there r 5 flashes b4 green light stayes on at the start

There are 3 components that control color, and it sounds like one of those are bad.
You will have to get it repaired.
I would talk to your local repair shop, and see what their estimate is, before deciding on repair or replacement.

The Hitachi 50UX57B is a 50 inch standard projection TV with a standard screen. It is not HD ready. If you need it, I think I can download the owner's manual (in PDF format) from Hitachi and foward it to you.

It sounds like the Hyper board is begining to fail....Does the menu shake too?

After 11 years???? OMG This set is a tired pup and should be put to reast. My experience with older sets and your complains are all capacitor problems and is only gonna get worse as the first time around repair will take several capacitors to repair. This set has no user serviceable parts inside so you should not attempt a repair suchj as this on your own.. This repair if you decide to go through the first time will be About 300 to 600 bucks the first time and cost will continue to raise till the sets put to sleep. Good luck
