Telecom - 56G 4:1 Multiplexer
MS4S1V2M 56G 4:1 Multiplexer
Product description
The MS4S1V2M is a SiGe 4-to-1 multiplexer (without integrated clock multiplying unit) designed for use in telecom applications up to 56Gb/s. The module accepts input data rates from 0.5-14Gb/s with an input sensitivity better than 100mV.
The mux can be used with existing equipment to generate higher bit-rate streams for telecom and datacom applications. The broad bandwidth of the input allows operation from 2 to 56Gb/s.

I see on this fuse box diagram below the ECU B, this is the description for that fuse.( could be a short somewhere in the circuit.) Multiplex communication system (power door lock system, security system, auto?door locking system, automatic light control system, headlight delay off system, tail light auto cut system, illuminated entry system, daytime running light system, wireless remote control system), air conditioning system https://www.autogenius.info/toyota-camry-2004-2006-fuse-box-diagram/

Circuit diagrams to may popular brand devices are given.
The door lock/unlock
input from the driver's key switch goes to the Door Multiplex control
unit (main switch), the Door multiplex control unit then sends a signal
on the BUS (CAN) circuit to the passenger's multiplex control unit; the
passenger's multiplex control unit then controls all the door locks. The passenger's door lock key switch inputs to the passenger's multiplex control unit, if the
locks work from the passenger's side key switch but not the driver's
side key switch, the most likely cause is the driver's multiplex
control unit (main switch) not sending the signal to the passenger's
side multiplex control unit. This could also be the drivers side door lock actuator. Hope this helps!
I'm afraid I cannot comply with your wishes, as there are copyright laws governing this, for one. (For existing circuitry)
Two, there is the liability issue. Take for example that I design the requested circuit, give it to you freely, and you or someone in your group is injured using my circuit.
Will state that this is a basic circuit design. I believe that if you 5 put your minds together, you can build this circuit.
Multiplexers are sort-of like switches. They "choose" one of the X inputs based on an input "selector" and output it http://en.wikipedia.org/wiki/Multiplexer
but what you're looking for is something that decodes a 4 bit binary input into a 16 bit output where for each possible input, one unique outputs out of the 16 are high. That's a four-to-sixteen line decoder.
They're kind of useless. Three-to-eight decoders are much more common.
Here's an article on how decoders work, and it shows an example of a three-to-eight line decoder. You can easily take that and extend it to be a four-to-sixteen line decoder once you understand the process.
Replacement of a main board might be tricky and not worth the money, I am not sure if you would troubleshoot or replace yourself.
- Have you opened the TV and seen the board?
- Once you open, can you actually remove it?
- If this is fairly new, (3-5 years) lead free solder would have been used, and prone to cracks
- Inspect every solder joint under high power microscope.
- BGA parts need X-ray, tough to get this done if you are not a solder/circuit board house
- If you apply pressure to BGA, when powered up, it may connect and work, this is a troubleshoot technique.
