Someone just gave me a used Dynex LCD L42-10A T.V. . The picture has some issues. There are bright green, blue, and yellow sort of blotches on the screen. Is this a bad inverter, Main Board, or something else? Dynex Tech Support said it was a bad projector lens. However, I can't find an existing replacement. Are they trying to get me to spend money with them? or was the guy on the phone an idiot?


Either way, I need to get this T.V fixed. Any help is appreciated.

A bad inverter would cause power issues, you have a problem with the imaging system so this could be a bad main board. You need to balance the cost of repair versus buying a new 42" generic lcd tv

Fortunately a mainboard, for this model, can be gotten for around $50 off Ebay. I just need to be sure that that's the issue.

Why would an LCD tv have a projector lens? That's crazy talk. Anyway, the issue is either with the main board or the lcd panel itself, A repair shop would have the equipment to hook up directly to the graphic output and test for proper signal. Maybe someone else has a better way to tell.

Thanks CleaverX. I like what you're telling me but, I would like to upload a picture of the screen to see if you or anyone else can give a more definite answer. Unfortunately, when I try to insert an image, I only get the option of uploading a URL. Do you know something I don't? How to upload pix maybe?
