Remote control issues (by 3 users)

Yes it is a quessing game. If we experts do not have the set in front of us to trouble shoot, but I will explain the process. First off to work on any tv set, your going to need a schematic diagram or should have one, or it will be a crapshoot. Next set up your osilliscope and multimeter. First check the B+ going to the IR sensor. If its at 9 to 15 volts, and is clean without distortion, Im thinking that is ok, but check the manual to see what it is suppose to be. Once the B+ is confermed good. Place the scope probe to the data output on the IR sensor while pressing a remote funtion. If the date is clean looking and is present then the IR sensor is good. If it is not good or noisy, replace the IR sensor. In the event its there, trace the data signal with the assistance of the schematic diagram, to the microprocessor, through all the jumpers and plugs and componets, like coupling capacitors or resistors, as I have found bad solder connections on the route to the microprocessor. If the same data signal is on the input of the microprocessor remote input, that is on the data output on the IR sensor, then replace the micro. This way of troubleshooting, has in the past, fixed every remote problem I have encountered with a remote intermittant, or no remote operation. Good Luck
