Unable to get an outside line / dial tone from my phone (KX-T7735-B) originally erroneously reported as a KX-T7335

If this is VOIP then the problem is with Comcast. The settings need to be set to recognize a two line phone. The long way around this is to find out the equipment they are using for switching from a digital to an analog signal and call the manufacturer for help.

The KX-T7735 is a proprietary digital phone that only works when connected to a Panasonic telephone system through a 4 wire line cord. It does not need an ac power connection to operate, it gets its power through the line cord when connected to a Panasonic phone system. This phone will not work if connected directly to an outside line.

I have a KX-T7735 phone in my home with 2 additional cordless for this unit. All of a sudden I heard maybe a slight click from the main unit, then there was no dial tone nor display info on the screen. Now...

I am sorry but I think that this fault seems beyond your limit but for a trial you can take a test.
In the front end of the unit where the telphone line comes in check the line detect sections , the opto couplers and the switching transistors , see for visible damage, check if the line voltage is high or is short with a low resulting in a dial tone loss.
Now check the sections of the adapter, the input voltage to the phone, has the voltage regulator shorted, if so check to see if the transistor, zener combination can be changed.
If the above two sections do not have any result then I am afraid there is damage to the processor of the base phone,you will have to get estimate from panasonic to proceed only if the cost is reasonable.

How do i clear caller id numbers on the kx-t7735

This depends on your system. For a TA series and maybe some others, personal CID can be cleared with the command 70*#. System CID clears from an Operator or manager's phone with 70**#.

Again, if your system is NOT a TA, it might be a different command.

Not exactly. The 7735 is just an instrument. It is forward and backward compatible with about 18 Panasonic systems. If the system is fairly new, it will be a TA-624 or TA-824.

Try looking for the system cabinet and then go here for the proper OM or User's Manual.
