RCA P46921 alignment issues

I am having the same problem. Just came across this information on another website. Hope it helps. (Both of us).... http://myweb.accessus.net/~090/how2adj.html#5.4 5.4 GE / RCA / PROSCAN Read the _ SERVICE MODE WARNING _ before proceeding. To enter service mode, push and hold the [Menu] button on the set. While holding, push and release the [Power] button, then the [Vol +] button. You will now have some information on the screen: "P0 V0" To actually be able to change these values, you must push [Vol +] on the remote so the information reads V76. Then pushing on the Channel +/- will change the "P" value. P1 - 3 are error codes. If there is a problem with the set that can be self-diagnosed, the "V" will report the code. These codes are available in the RCA repair manual. P4 - 7 control the horizontal size, shift, vertical size and shift. You may also find a summary leaflet for the service tech clipped somewhere inside the chassis. The procedures for getting into the service mode, as well as the service items of interest will be there. If you're attempting to adjust color or geometry errors, you'll need the Video Essentials DVD, Laser Disc or some other source of test material.

Having sound issues, just unplug your TV for 10 minutes and it will reset itself...almost like rebooting a computer. I was so ticked as my sound just went out yesterday during the buckeye game, but the picture was perfect. Found this issue is a common topic on several forums. Just try it and save some money. One more note, there is speculation that the Spike TV channel causes the failure. I'm not an expert, but something to due with signal overload? Good luck!
