Customer support-via email between me and a customer from Belize part 2

Jorges : I had already disconnected the collector from board, and the snubber and diode that goes to pin 1 of fly back and still there is short to that pin from ground. Sir this is hard. Do you think maybe I go check elsewhere else, or is it time to do voltage testing...although there is short?

Customer support-via email between me and a customer from Belize


Hello Mr. Humphrey,

Since studying your eBook, I am now working on a second TV. This one is for my Boss and is a Precision PTV 29R89S with Chassis TMP8823CPNG5VAH. However sadly I can't find the schematic nor the pin out of the flyback.

Customer support-via email between me and a customer from Florida (USA)



Hello there Mr. Humphrey!
This is Gill from Coconut Creek, Florida (USA).
I just bought your book a few moments ago, and I’m enjoying reading it.

On chapter two you mention, that inductors allow low frequency to pass, and make it very hard for high frequencies to pass; and that capacitors allow high frequencies to pass but make very hard for low frequencies to pass.

Customer support-via email between me and a customer from Belize


One of my latest customer Mr. Jorge from Belize send an email to me with an issue which he wanted me to explain a little, let hear what he is saying.

Hello Mr. Humphrey,

Please just one question on the CRT course that I am not sure about. 

1.   I reached chapter 9 “on how to find a shorted components using series bulb on the primary power supply fast!”… Where it says you remove a pin of some components. When I do this, do I re-solder back a component if it is ok and go to another or do I leave the pin out and go take out the pin of another?

NEC TV 21” CRT sound not ok but picture Okay


 This TV was brought in my shop with the picture ok but the sound was not stable…sometimes good and other times not.

I opened the set and went straight to the speaker (power off and power cable disconnected from the power outlet).
