Hi.. Hopefully someone has run into this problem with this model before.. KP-53V80 comes on fine but continues to get brighter (all 3 guns) and then finally goes into shutdown anywhere from 20 minutes to an hour. The oddest thing- when screen starts to get bright you cannot get menu button to activate and tv looses on screen display completely (SOMETIMES!!!). 5 blinks of course (SOMETIMES!!) indicating video problem but I drew a blank looking for the answer last night in the customer's home. Any suggestions appreciated!
