I'll have to go over the receipt again to make sure. Is the Digital PCB an expensive thing to repair or replace? Now I'll try to explain the way I have everything setup, with the Comcast box and the recorder. It's not as complicated as it's detailed. I don't have a digital tv so I had to get a box. And with the box, you have to keep the tv on channel 3, and change the channels through the remote and the box provided. So unless I wanted to watch tv, while recording something like I could do before, I had to do a split, one going from the box to an RF modulater then an A/B switch. And the other going to the DVD recorder, and through to the A/B switch. And then the A/B switch to the tv. It doesn't work exactly the way I hoped it would but it has worked. The Comcast box has two inputs, 'cable in' and 'to tv'. I can try a find a picture if that'll help. And I could manually change the channels on the box, but I want to be able to schedule recordings while I'm at work or away. And the only way I can think to do that is with an IR blaster or something. And I did consider that for a period, but I didn't go with it. I hope that was detailed enough. Thanks.
I'm assuming that Best Buy "plan" didn't provide for repair at one of the two corporate Panasonic Service Centers in Elk Grove Village and Elgin Illinois.
With a complaint of a failed DVD Drive either of the corporate Panasonic Service Centers would (probably) have tested the Digital PCB, DVD Drive and DVD Drive onboard controller board in order to narrow down the problem.
A local multi-brand shop may have had no clue that the Digital PCB (currently $338.36) or the onboard DVD Drive controller board (currently $30.19) may have contributed to the machine's problem(s). When the non-Panasonic shop replaced the DVD Drive they may have swapped the original onboard controller board to the "new" drive in order to save $30 when that board may be part of the problem. That onboard drive controller board is seen in the first photo.
That's why the only places to repair a Panasonic recorder under warranty or out-of-warranty (with the $130 flat-rate repair mentioned in the thread "Panasonic Repairs? The ONLY place for warranty or out-of-warranty service!") are the two Illinois locations.
As to the Comcast STB, if it has only an RF input and output it is most likely the Pace DC50X Digital Transport Adapter (DTA) seen in the second photo.
For your set up you need a regular Comcast "digital" converter box that also provides, at a minimum, composite outputs.
The following set up is illustrated in a later post:
Run the raw Comcast coax cable feed to the DMR-EZ28 RF input. Run the EZ28 RF output to the Comcast converter box’s RF input. (Since the EZ28 has an unmodulated RF pass-through output there is little, if any, loss of signal quality and no signal source conflict.) Connect the Comcast converter box composite outputs to the composite inputs on the EZ28. Record clear QAM channels from the raw coax cable feed and scrambled programming from the composite inputs.
Run the Comcast converter box RF output to one side of a RF A/B switch. Then run the EZ28 composite outputs to the RF modulator. Run the modulator’s RF output to the other side of the A/B switch. Run the RF A/B switch RF output to the TV’s RF input. Use the RF A/B switch to select among the viewing sources.
