Black shows upas darkred, If image is on ...




By psilocybe on Dec 05, 2008

When I turn my tv on without an input connected, the screen is a dark red color.  As soon as i switch it to any input so that there is an image on the screen, bright red pixels show up.  Everything still has a red tint to it though.
I have changed all the color options including the color temp with no avail.

Tech support of course will not just tell me what this issue is, instead they will tell me to send it in for diagnostics and charge me a fee for that.  Isn't that what we were trying to do on the phone?  I thought so but apparently not.

I figured i would take this to the internet and see if i could get some help.
I did take the back panel off to check for loose wires, and bulged capacitors but did not see anything like this.

I have only had this television for 13 months.  Sadly no extended warranty as i wouldnt have expected to need one.

- Well, when I press the menu button (the menu options are all blue) the menu shows up.
When i am watching cable i do get other colors but they are very bad.

I can try and post a video if that would help

- No.  It stays about the same

- Just to clarify, AD Converter = analog - digital?

Again, this happens with any input, or with no input at all.

- To skotkolr, Thanks for trying.  But i stated in original post I had done that.
This happened spontaniously while watching tv.  Not a settings issue.

Clarification Request

sounds like a signal processing problem (AD converter) , posibly a bad voltage referance in the input circuit.
