Question about Pioneer PRO-710HD 64" Rear Projection Television
It does not sound like a convergence problem as you stated that all the lines match up and are ok??? You have space at the top and the bottom, as well as on both sides? Well my friend it sounds like you have a power regulator problem with the main power supply, because it sounds like the voltage is low and causeing the set to have a smaller then normal picture. Check the Main B+ first. I dont have a schematic but if you need, I know lots pof authorized pioneer peeps, and can getbwhat voltage and what part is most likly bad. We hardly repaired the boards as they(pioneer ) did not have most of the descrete parts and mostly had the boards themselfs to replace. You could also take out the B+ regulator board and have it rebuilt at PTS. They have a web addy of http://www.ptscorp.com Look them up and get their tele # and call them to see about the replacement cost. If they can't help go here Main support number800-421-1606. Good Luck
