Question about Symphonic WF-719 19 in. TV/VCR/DVD Combo
It can be the remote sensor, or the circuitry that works with it. I don't know its exact location for your model, but you can usualy find it, because at its location it looks like a little black or dark red window in front of it.
The sensor and its related circuitry are servicable. To find the exact fault will require using a DVM and an oscilloscope to trace down where the signal is stopping from the sensor. The sensor feeds the main uPC controler via a number of components on the circuit board. An experienced service tech should be able to troubleshoot this for you, and replace the defective parts. On rare occasions the fault can be with the uPC itself.
It is also possible that there is a cold solder connection on the circuit board that is stopping the remote sensor from getting the remote signals to the uPC.
