Question about JVC LT42P789 42 in. LCD TV

1 Answer

The screen shows ''Weak Signal'' and no picture, even though audio is coming through from both the Cable DVR box and Blue-Ray player. The cable box connects to the TV with an HMI cable - all five TV inputs show ''Weak Signal''.

Mine did the same thing once. I think all I did was hit the setup on the remote, and let it run back through all the channels and then it worked just fine.

I hope this works for you.

The picture seems very coarse and has diamonds running across it


Hello: In standard defintion the picture is showing in 480p which is the lowest resolution for LCD televisions, The picture will only look as good as the signal its getting, If you have cable then it should look some what better even with std defintion. The Diamonds/triangles are caused from a weak digital signal or weak broadcast station. This is a normal occurance for LCD televisions as the picture is put on the screen in blocks. I would not say your television is bad, just a poor or weak signal, If you are using a digital antenna and not cable, then you might try purchasing a signal amplifier to boost the signal before going into the set.

Weak signal showing on my l e d samsung haven't used it yet (new)


Hi,

Try to double check the power cable is well connected if so you have to know that some screens come from the factory with some problem and in this case you have the right to replace it from the seller.

Audio only, no picture


Audio without video is usally a vertical or horizontal deflection problem with the DPTV chassis and Mag 1 chassis which is what you have. You may need a new deflection Large signal board. If you would like a link to one of those boards let me know.

Picture problem


I have the EXACT same problem with my Sony SDM-P234 23" HD/computer monitor. I know it works (and it works great) with my DVico PCI card with my computer. It outputs in 480i, 480 p, 720p and 1080i with clarity on a simple indoor RCA HDTV antenna. I get the same quality (1080i) picture for the same three seconds as does lewy. I can also add that the digital coaxial output delivers 5.1 audio to my amp and it stays on even after the picture cuts out. Please help.....Comcast sendsa 'technician' out to service it and...well....did I say he's a 'technician'? He changed the box twice and says it must be my equipment. I guess its an act of God that it works with anything else.... I mean....its been checked out by a Comcast 'technician' after all.
