Screen Crack my screen on my DX-PDP42-09. I'm trying to figure out what part number I would need to fix it. Can I just use a peice of clear plexi glass. It not a major crack. no color is off on it.

No you cannot replace the Plasma screen with Plexi glass. If the picture is still good,you should not change it.The cost for the Plasma screen is very expensive. The reason is it a electronic matrix of circuits. The wiring is internal in the Plasma screen and is use to operate the transistors that change the Plasma colors. You best bet is to try to find a television just like yous with a good screen but not worth repairing. You can find these type of televisions on website like e-bay or craigs list. The part number will be located on the Plasma screen itself. You may be able to get the part number from the Dynex customer service department You can call them at this telephone number. 1-800-305-2204 between the hours of 7am-12am CST. You can also go to the website at:(http://www.dynexproducts.com/pc-704-23-dynex-42-720p-flat-panel-plasma-hdtv.aspx)contact customer support through the e-mail service. Give them the model number of you television and the problem you have with the broken screen. They will be able to help you get the part number and tell you how to find a replacement screen. I hope this information helps you with your problem.
