This site has helped me before and I'm hoping it will again. I have a 6 yr old wd-65833 that I've replaced two bulbs in, a ballast, and a power supply board. It has started doing something really odd. When I go to turn it on it doesn't recognize any remotes (directv or OEM), I turn it on from the front panel and the on screen volume indicator shows 00 and the remotes do nothing. If I hit the reset button or unplug it, and turn it back on from the front panel it then sees the remotes and the volume can be adjusted. Could that be a logic board problem?
