Answers :

Hi,
Problem seems with main tuner in this tv as other AV inputs working fine so please replace main tuner (TU2) to solve this issue.
There are two tuners mounted on A board TU1 and TU2, please replace TU2 and part number would be written on tuner itself.
TV is approx 10 years old so I would recommend that do not spend lots of money on it.
Thanks.

I have a vizio model GV47L FHDTV 20A LCD TV. We purchased it 4 years ago, this morning it began making a hissing sound while we were watching it. The picture also got dark and distorted. I've tried troubleshooting the problem and have realized that the sound remains constant regardless of the volume level, or input( even muted). I'm sure it's not an issue with the cable, because the problem persists with the cable box off. I've disconnected all inputs and and the sound bar, but the problem is th

Dvd connection we have our direct tv cables hooked up correctly we believe, because we get the signal just fine. When hooking up the A/V cables from the DVD player to the other ports available however, it doesnt pick up the signal after we change the Source on the TV. So basically, everytime we want to watch a dvd, I have to unhook the direct tv a/v cables and hook up the dvd av cables in the same ports. It works just fine then. But we would love to not have to go thru that process everytime.

My Denon receiver, mounted in another room, has HDMI inputs from my DVD player and cable TV. Signal goes from receiver through HDMI into a signal transmitter and then to the TV via Cat 5 data cable and signal receiver. The signal frequently drops out, and especially if any light switches are turned on/off. Is it likely the problem is the result of an electrical wiring problem, or could it be a problem with the Denon receiver itself?


It would seem that the transmitter and/or the receiver may be causing all the fuss...or the cat 5 is having issues...the cat5 cable may have some defect...try using another cat 5(even if it's 6ft long,move receiver closer to tv/dvd and use transmitte ... Flat Panel Televisions
