Hi all.
Anyone have any info on a Diamond Vision DTV2822 20" Tv?
It is made in China and I am not sure if there is any service support for it :wallbash:
Checked for cold solders, caps, supply resistors & there is no burnt or any components getting hot.
The set is turn on by the remote control & a whinning noise is heard coming from the start up transformer T901. Supply voltage 130vdc & 14volt supplies are coming out of the transformer T901.
There is no high voltage to the picture tube heard on start up & the tube heating filament does not glow?
TV's are not my electronics strong point. I have been it audio repairs for many years. Thanks for any help.
