Hey guys, after reading this thread through searches for certain posts for the better part of two hours, I still wanted to make a response and be 100% clear before possibly sending my TV to the graveyard...
Currently I am having the problem many others were with the image persistence of the "No Input Signal" box at the top-center of the screen. I read that firmware version 1.3.0 fixes that, while others were unlucky and did not get it fixed.
My current firmware on my own TV is 1.2.0, dated at 2007, Sep 7. My model is TX-32F430S and Part# is TW-51122-C042A. I went to Westinghouse's site and they only have a link for a firmware of the name "01_OSD_FW_V1.4.2", but low and behold the only part # I was able to select was TW-51121-C042A. I read someone said installing the a piece of firmware that had a wrong part # could brick your set?
All I really want to know is how can I get rid of this No Input Signal box that is persisting. I read you could update the firmware to 1.3.0 to fix it, but I want to get the exact proper way to from 1.2.0 to a newer firmware that fixes this issue.
Edit: I have also read of things like jscreenfix or using a blank white image at full screen and leaving it there for multiple hours fixing image persistence. Any truth to that theory, and would it work in this case?
