It would appear that the remote control does not work since the tv will power on and function manually. However, after several univeral remotes it seems that the problem lies within the little led screen on the tv that receives the signal from the remote....now where do I go from here to repair it?
On the little PC board which has the pushbuttons on it, mounted right behind the buttons on the front of the TV, is the remote (IR) receiver. It is a little black box with 3 leads soldered to that board. One pin is grounded, one pin is +5 volts and the third is signal. The signal pin should be a little less than 5 volts, and when you use ANY remote the signal pin should have inverted digital data (about 4.5 to 0). If you measure the signal pin and it is near zero volts, replace the receiver. If the signal pin is around 4.5 volts, replace the remote.
