dvd help

Hey all, I have an 04 Tahoe I just got about 2 weeks ago. I have googled and searched forum after forum for the issue I am having with my RSE. It has the stock Panasonic RSE (flip down DVD). Stock Head Unit as well. I get video but no sound all I get is an crackle/static through the speakers...

I have a 2004 yukon xl with a Rosen DVD system. The DVD player is mounted under the driver side passenger seat. My son spilled a drink and it has quit working. I took the cover off and cleaned it out inside. It worked for about an hour and now it cuts on and turns right back off. Has anyone else...
