Repairing /Finding the TSOP in trackpad cable of MacBook Pro mid 2010

I am at a location where, finding this is trackpad cable is quite difficult, and everything is just stuck, due to virus.
Do you know where is the thermal sensor in this circuit
The trackpad and cable are not documented anywhere I have seen or can find. Check that the fault isn't in the i2c sensor communication lines on the MLB to the trackpad connector first if you don't have a spare trackpad/cable to rule them out. TBH, apart from a visual inspection for obvious signs of damage, I have never tried to repair one myself. I have always just pulled one from the spares pile.
well thermal sensors can be replaced with transistors, if it is on the MacBook Pro motherboard as there are basically transistors, and I have the skill and tools to repair, if I can get the schematics for this flex cable, but unfortunately I can't find it, and even if the transistor is build in some ic, that can also be bypass by adding a new similar transistor in the line, I can get them from different bad boards or so, but do you know where the thermal sensor is in this circuit or not ?
Nope. And therein lies the issue. We could all replace it if we knew where it was or had some documentation on it. You can try posting over at https://boards.rossmanngroup.com
If anybody can answer your question they'll be lurking on there. Other then that it'll be down to good ol multimeter detective work. But that would be made easier if you had a known good one to compare readings to.
thanks for trying to help me, yes I had also tried but the trackpad cable is not documented anywhere, I have checked the socket and traced the data and clock lines, there are fine from SMC to socket and even up to the isight camera connector,
there are few things I want to share what I have tried to figure out
1. This problem is intermittent.
2. There is I/O error TSOP (palm reset sensor) if I see it with ASD ( if the problem occurs )
3. And when the MacBook Pro boots without this problem, this sensors keeps working ( means the temperature increases as well decreases : means it works perfectly fine) and it keep on working if I don't shutdown the MBP, if I put the MBP in sleep then also the sensor keeps working, but the sensors stops working if I shutdown it.
4.and the sensors starts working if I shutdown and restart it for few times.
5. when the sensor is working, I can connect the trackpad cable from motherboard, I can read perfectly, and if I disconnected the cable, and reconnect ,it keeps working every time, BUT it stops working the moment I shut it down and start again.

I don't have an active membership of that forum, if you have one, can you please post this query on my behalf please

Can't really help you with it. Seems like you've done more then I would have already. When I get a tsop error I just replace the trackpad and/or cable. If that doesn't fix it then I check the data lines. I tried investigating it once to attempt a repair, and came up with more questions then answers. You are currently travelling a road that we all did at one point. Maybe you'll figure it out, maybe you won't, but if you want advice on it rossmangroup is the place to ask. I gave up on it and just replace them now. An intermittent problem is the worst, if it doesn't make sense it really makes it hard.
