Crimestopper replacement brain?

My soldering skills are not good enough to attempt that. I would rather find a shop or person that could do so. I'll check out some electronics repair places and see if they can do it for a reasonable amount. Would it be worthwhile to replace the other SMD chips while I'm doing this?

No. No need to replace the rest of the chips. The big square one you can't replace, because it contains the firmware of the RS. The one on the left is a relay driver, which is cheap, but since you only have issues with the inputs makes no sense to bother with it. I hope you will find someone to do the replacement. I would have done it for free. It will take 5 min to someone skilled.

Thanks again for your help. If I cannot find a shop locally, I'll be glad to send it to you & PayPal you some $ to cover your time & expenses. I'll let you know.

I would do it for free. I should even have those 4052BT . They fail in the Mercedes light control modules and I bought some to have.

Would this work? It does not say it is SO-16 like the Mouser listing does, it says TSSOP. I can probably get these faster than from Mouser. Phillips HEF4052BT

Let me try that link again: Phillips HEF4052BT

It looks like ebay links are blocked. It is item #252232497063 PHILIPS HEF4052BT 16-Pin TSSOP 4-Channel Multiplexer New Lot Quantity-25

I see Mouser segregates them by SO-16 and TSSOP, so I'll presume the ebay ones won't work. I see Mouser has 2 variations in stock: 4052BT,653:Multiplexer Switch ICs DUAL 4-CHANNEL 4052BT,Q100: Multiplexer Switch ICs Dual 4-Channel Analog Multiplexer They also list two models on order: 4052BT,652: Multiplexer Switch ICs Dual 4-Channel Analog Multiplexer 4052BT,013: Multiplexer Switch ICs Dual 4channel analog multiplxr/demultplxr

The Ebay item is the correct one and it's $6 with fast and free shipping. You can purchase it. http://pages./link/?nav=item.view&id=252232497063&alt=web The package is called TSSOP

I have sent you a private message since I cannot find a local shop to make this repair.
