I am Currently working on teac model ct-m5122h but this one is giving
me some trouble, this is the first one of this type I have seen.
the 2 faults i have now are the audio dips in volume from time to time
and Horizontal shift to the left of the screen. you can see a thin
black line on the right hand side.
I have replaced all the caps in the p/s on both sides B+ is stable
with very little ripple.
If anyone can help me out with any advice or a schematic and service
menu codes or procedures it would be greatly appreciated.

David does the audio dip when the horizontal shifts.
Check for dry joints around the yoke connector on the mainboard.
Also check for any shorted inductors in the horizontal stage and also check
the vcc rails to the sound chip for variation when the sound dips.
Cheers

No the shift is there all the time and the sound seems to dip at any
time I have looked at most of the power supply rails with the cro but
have not been able to find any thing that stands out.
I also tried high country to get a manual but they didn't have one.

Yep thats right you will have to go direct to Teac for that one.
Phone 0396442457 / 0396442411or ring Speedy Spares on 0393761333.
Also check Capacitors in horizontal stage I would suspect one of the poly
caps.Audio is a funny one could be a faulty audio chip doing it.
Let me know how you go
Cheers
