Proview 3200 Flatscreen with HDMI Problem

Hi - I have a Proview Flatscreen TV (about 3 yrs old) and use AT&T U-Verse (fiber optic cable tv) through the HDMI source on my TV. When I turn the TV on, and select HDMI mode there is 0hz, when it is usually 60hz (at least). So, all I get is a blank screen and instead of accessing my cable box, so that I can watch tv, any help would be greatly appreciated!

Maybe the input on the tv needs to be adjusted to work with the cable tv for example in the tv menu where you can adjust the sources for the inputs maybe it is set to something like RGB instead of HDMI. If you have a user manual consult it on how to change the input devices. Good luck.

Why can't I get the DVD player to work? I have it hooked up to a cable box.


im wondering why you did not connect it to the tv ?? but instead to cable box , does it have a pass thru capability ?? does it need to be off to pass thru ?? as most dvd player don't have a rf output but instead use a hdmi or composite signal output , would it not be easier to connect one of these to a spare input on tv then when u want to use dvd you only need to select the proper input from tvs source button to view the dvd ??

The color on my TV is all pink. I have tried a hard reset but it didn't help.


Your TV has lost a GREEN color from a basic color palette (Red-Green-Blue). It is often caused by:
- damaged LCD cable (which connects the display with a signal board inside the TV),
- damaged video signal cable (ex. SCART, HDMI, VGA),
- damaged video processor (on the signal board).
I can't give you a more accurate answer, because I don't know what is your TV mark and model and, in what situations you have the problem.
