I suggest that you check out the website below:

visit Youtube.com to see how they do the soldering work and get books on how to read schematic from amazon.com

Remember also to visit electronics forum.

Make sure the B+ voltage is good otherwise it will have a squeeze display vertically. Check also for dry joints in the horizontal yoke coil section and make sure the yoke coil is not shorted.

Symptom:
1. Vertical height reduced from top and bottom side.
2. Vertical Line
3. Vertical height reduce from Top or Bottom(one side only).

Advise:

First of all need to be checked loose connections and Leakages of lower value capacitors in vertical section.

FOR SYMPTOM 1:

Check vertical size Variable, Capacitors lower value / leakages.

FOR SYMPTOM 2:

Check loose connections, vertical size Variable, Capacitors, open resistors in up-to 3 watts, and vertical IC.

FOR SYMPTOM 3:

Check vertical balance VRs, Vertical IC.

Thanks you
regards
Amir mukhtar
