After nearly 4 years my LVM-42W2 (Westinghouse) has finally given me a problem. I am hoping/thinking that it is worth fixing - and if it is something as simple as a board replacement I can do that easily enough... but need some help in diagnosis. I looked through existing threads on the LVM series and found nothing like this, and would really like to try self-diagnosis before giving it to an expensive repair shop who will charge me up the wazoo just to tell me it can't be fixed.
2 nights ago I turned it on and was greeted with a heavily washed out screen - almost as though the brightness and contrast were completely out of whack:
This happens across ALL inputs - even ones with null signal or nothing connected, and also while switching inputs... at no time does the washout dissipate:
I also notice that there are columns of flickering pixels in the infobox that appears when switching inputs, and have verified that these are not present at any other time other than when this box is up on the screen, and they are not dead pixels - they are perfectly fine with other solid colors from an external source. You can't see here as it is a freeze-frame, but to the eye they look like long, black lines through the box, and flicker on and off in different sections at random:
Something that is really interesting is as soon as I enter the menu for the tv - the screen darkens significantly, losing a lot of the washout effect, and stays that way - EVEN when I exit the menu. With further, extreme adjustment I can get it to a watchable level, but the color saturation is way off, and there is still plenty of gray washout. In addition - any dark areas like the top and bottom letterbox bar and the lower-left corner where the image fades to black flicker at random intervals.
I am not thinking it is the panel itself - because it does darken in the menu, and those pixels only appear to flicker when that one box appears... I figure it is a board or controller or something else - but have no idea what/which and would hate to start throwing parts at it if it is a lost cause, or have it end up being the last part I replace, ya know?
Would appreciate any info/feedback from people who have had any similar experiences with their own panels.
