Question

Westinghouse tv circuit board

A little education please. I've purchased a replacement video motherboard, 1108H1191H, for a Westinghouse VR3730. The antenna port had broken off the original board. The replacement doesn't work. No image or simple screen message such as 'no signal', volume display or menu items appears. Those functions worked on the original board. Is it a safe repair to remove the good port from the replacement board and move it to the original board, which had the broken port?

And for my own benefit, why would identical boards with a different part number not work. Other's are available, but would like to understand the reasoning for not being interchangeable.

Yeah, I know...old unit, but I like to tinker.

Thanks in advance.

OR...

This is where you need a service manual.

Sometimes boards need the tech to get into the service menu to set the board to your specific model TV.

But no tech I know today moves chips between boards since the makers are not publishing schematics or such data in the service manual.

-> Frankly if it's just a broken antenna port I might have opted for an external tuner.

Like one in the vcr I have as part of the ensemble? Or a stand alone. Thanks.

If you have a tuner in

Something you have, that's your cheapest exit. There are stand alone tuners out which might do better or be needed as many old VCRs only have pre-HD tuners. It's a big world so I can't know if your country ended PAL or NTSC transmissions.

PS. Most likely not a good idea to repair.

Why? "43" Westinghouse WE43UJ4118 4K UHD Smart LED TV on clearance for $119.98. Shipping is free" so when I checked for a mainboard for another TVs that board was 99USD so when parts get that close to a replacement TV you know what to do.

You can sometimes sell off the dead set but it's really not worth much so if you can get 20 bucks you did great.

Yeah, I have electronic recycling nearby, so that's the end game.
