I have a standard Sony 32" tv. Recently, in the lower left portion of the screen it has begun displaying a red/pink patch in the shape of a half moon that goes from the edge of the screen and is approx. 1" by 1". We have moved it recently while rearranging furniture. Is this something that can be repaired by adjustments? If so, does it have to be done professionally? Will it grow like the blob and take over my screen? I have digital cable using the RF/antenna (I think I'm identifying this correctly) connection and dvd w/s-video connection. Any suggestions will be appreciated.
