GIRRO LED TV NO AUDIO PICTURE OKAY

A colleague of mine had a friend who wanted her television checked by a technician and he asked me if I can help her friend sort out the audio problem with her television

I fixed a date and off we went on site with him as my tour guide, I carried with me my usual minimum tools to help me with this assignment.

We found the television ON and the kid was watching the screen although there was no audio and I think this was good enough for a two year kid.

Sinotech CRT television with rainbow screen now repaired

One of my customers from Zimbabwe  Mr.Beau Friend send in an email to me a few days ago....let’s hear what he was up to.....

Greetings Humphrey,
A friend brought in a Sinotech CRT TV for repair - my TV repair experience is fairly limited hence I purchased your recent book to assist me in getting up to speed in this field of repair.
I've sent a picture of the fault - I have a very pretty rainbow effect but not exactly sure where to look for the fault.
I replaced a 1k resistor that had dropped to 270 ohms in the HOT circuitry but still the same - I've thoroughly checked the PCB for cold joints. Any suggestions?
Many thanks and kind regards,
Beau Friend
Zimbabwe
