Hey guys, this has probably been covered before, and I have read a lot of material from this site and others about LCD image persistence and ways to fix it, but I still have some concerns.


The TV I am having problems with is a Westinghouse TX-42F430S, Part# TW-51122-C042A. I have read a few ways on how to fix this and I still have not found any luck, or waited long enough with each solution. I just turned my TV on from letting it sit there for 48 hours (with the power cord in though, does this matter?), and there is still the faint outline of the box from the "No Input Signal" message when you are on an input that is not receiving anything.


Possible solutions I have read about are displaying a white picture for a long time (12 hours?) to reset the crystals, although I have also read this reduces the life span of the TV more than normal, any truth to that?


A specific solution to my model of TV I read in the official thread for it was to upgrade the firmware from 1.2.0 (Which I am currently at) to 1.3.0 to resolve this common issue with this model. The problem with this is Westinghouse currently only offers 1.4.2 and I would just upgrade to this if their site only let me select a TV model and part number that wasn't the exact same as mine. It lets me select the correct model, but the part number that they make me select in order to show me the firmware I need is TW-51121-C042A instead of TW-51122-C042A, which is what I have. There were reports of people in that thread talking about possibly bricking the set by using the wrong firmware. I collected the 1.3.0 firmware from that same thread named "SusanII_v1.3.0_20071026" but am a bit apprehensive to use that to try and fix this issue. I also collected a modified firmware version made a by a user here named "TX-42F430S - v1.4.0 - editted" that has recovered "bricked" sets.


Can anyone here help me or point me in the right direction as to what I should try next? Anyone with my model of TV or knowledge of it would be doubly appreciated.

I have a viewsonic LCD monitor that does this.


I've always successfully cleared up the display by turning it off for a few days or it will take longer but turn it off overnight for about a week. no you don't need to unplug it


it is bright images that get the pixels stuck into a more open state when left on the display for long periods of time right ? that's what happens on my viewsonic.


i wonder though how your able to make this happen on a TV if your using it normally?


its easy to see how i did it to my viewsonic many years ago because i would leave it on 24/7/365 with no screen saver on my computer so the bright parts of my desktop background or apps i left open on the screen would eventually cause this to happen but it would take at least a good 2-3 days for it to occur and let me tell you i have left some things on it for weeks if not months on end when i used to use it as my secondary monitor

anyways i never see it happen anymore because i use it strictly as a TV display via an adapter box hooked up to my cable box to watch TV on when i'm sitting at my desk and never have a problem with image retention anymore

You might want to check out the website jscreenfix.com, which offers a free applet for dealing with stuck LCD pixels; Some people have reported success using it to revert stuck LCD pixels to their proper state...

Ah yes, I have used this on the same TV set to fix a stuck pixel (1 red pixel that was really annoying) and it only took a couple minutes. I was not sure as to the veracity of the program for removing image persistence, but I think it is worth a shot at this point if it was able to successfully unstick the pixel.
