I am thinking of buying this meter since it has scope on it to help me fix tvs. I was wondering if this would be good for repairing tvs and how much would be the most I should pay for a used one in good condition. Any input would help. Thanks

Re: Fluke 123 scope meter
One scope meter with out warranty it is a risky move.
I have see many on eBay " sold as is " or untested, which is the same trap.
Most such units they are sold because their repair from Fluke as out of warranty items costs usually the price of the item as to was new.
If you find a used one in good condition and the owner of it accepts to transfer to you and the warranty rights ( yes they are transferable), then get it.
The Fluke life time warranty become lately a seven years plan, I would expect that a pricing of 800-1000$ sounds reasonable for a used one plus warranty.

I am repairing a Fluke 335 clamp meter. After contacting fluke it appears there is no service manual or circuit board/ component list available. I have determined that there us a faulty PNP bipolar junction transistors shown in the pictures. I am having trouble sourcing this transistor. I pulled a good one off of the board and tested it with my component analyzer but I cannot find anything that matches the specifications. Any help locating this part or a replacement would be greatly appreciated.

I read EBOOK of Testing Electronic Component and found that
"In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."
Is it really possible to test small ceramic disc capacitor with analogue... -
