Boots branded b/w 5" tv - UK Vintage Radio Repair and Restoration Discussion Forum

Hi guys
I have a Boots branded 5" b/w tv. Model is MTV5
Any suggestions where I may source circuit diagram ?
It has the following issue.
When the volume is turned up the height jumps and up and down, its not much and happens rapidly in sync with audio, higher the volume, the more severe.
My first thoughts is power supply becoming unstable when volume turned up.
many thanks

I would think a lot of these 5 inch TV's will be similar but rebranded, try a search on google for 5 inch CRT TV service manual, it may give you what your looking for, I got a hit right away.

It is sometimes possible to identify the manufacturer from the type label, or if that doesn't work, from the printing or labels on the main board.

I posted a circuit of a 5" TV in this old thread. It may be similar to the Boots set.
