No special tools. Take off the back, and you will see the matching board you have. Make sure unit is unpluged.

SOURCE: Need to Buy a main system board/controler board for BenQ DV3750

Really Did not find a solution because we already know the problem. i.e the mani/digital board. BenQ will not sell us the part. We are still looking for a supplier.

NEVER NEVER Buy BenQ

SOURCE: removing/replacing main drum bearing on a zanussi WDT1085

Yes you do need to remove the drum, it entails stripping the washer down, and it is normal practice to replace the complete drum half with the bearings pre-fitted..
It is not a job to undertake, unless you feel competent to do do it, as it entails al ot of work and time..
Good luck if you decide to proceed.
Plz rate my suggestions.
.Thanks.

SOURCE: 2002 Toyota Highlander AC main control

Before tearing out the AC control, does the temp knob feel loose or wobble alot more then the fan knob? If so pull the temp knob straight off. Look at the small nut around the shaft the knob came off of. Its common for them to come loose. Just tighten it up some and reinstall the knob. Your temp will work normally now.
This fix is for the manual system not the auto ac system.

SOURCE: Need more detailed Instruction on how to replace heater core

Answer
Once again you have an ALL DAY JOB ahead of you. YES, You have to remove the "whole dash".

However, Sometimes you can get LUCKY and only unbolt it without pulling all the wires and cables and junk and it will come back just far enough to be able to remove the heater box.

NOTE: I have found that on SOME Ford models.,:

They install the heater core in the interior plastic housing and mount it on the firewall with the studs protruding thru the firewall then they put on the NUTS from the engine compartment side onto the bolts to hold the assembly onto the firewall.

Then when they mount the engine compartment housing OVER these same studs that protrude thru the firewall and then they install a SECOND NUT to hold the firewall compartment on.

So you have 2 nuts on the same bolt. Therefore you have to take the engine compartment side housing side off FIRST and then you will see the set of NUTS that hold the interior housing onto the firewall,
