I NEED THE SCHEMATIC FOR MODEL CS-35MX1. ACTUALLY JUST THE SCHEMATIC AREAT FOR THE VERTICAL IC AREA. THE SOLDER WICK REMOVOED SOME OF THE COPPER AND I NEED TO USE JUMPER WIRE TO FIX, AND IT IS HARD TO TELL WERE SOME OF THE PINS GO.
THE SCHEMATIC OR AS I SAID THE VERTICAL AREA IS WHAT I NEED. ANY HELP IS MUCH APPRECIATED, THANK YOU.

You either have a cold solder connection on the vertical output IC401 or a failure of the Vertical output IC altogether. The part number should be labeled clearly on the front of the chip and is likely LA7836 or LA7837. It's difficult to reference parts on a set this old. Remove the chassis and visibly inspect the solder connections. If they look good, replace the chip. Good luck
You will need a soldering gun that has a smaller point and rosin core solder (smaller solder is better for this job) cost about $20-$30
Best way to fund the vertical IC without a diagram is follow the Green and Yellow wires from the yoke( coild around picture tube neck)
the Green and Yellow wires are the vertical winding and will get you close to the vertical output IC which should be standing straight up with about 8-10 pins going through the circuit board, using a magnifying glass verify if the pins have circle cracks around them and just solder them each heating them for a few seconds flowing solder to the pin not the soldering gun. verify that non are shorted (soldered) together that aren't suppossed to be. Sometimes the end ones or a few are together (usually a ground spot).
hope this helps
The vertical deflection circuit has a fault.
Try hitting (not to hard). If it comes back, even for a short time, it is a cracked circuit or solder joint.
No results, there is an IC responsible for the picture to become whole again
This is a problem with the vertical circuit and is relatively common. If you can solder you can fix this yourself. First try resoldering the pins on the vertical IC. If that fails to resolve the problem, replace the IC. This IC is a small flat IC attached to a heatsink having about 11 pins or so. Is will be marked LA7837 or something similar. Post the marking here and I'll confirm the part.
Vertical output IC most likely needs to be re-solderd. However this model is famous for the CRT leaking coolant in the area of the Vertical output IC and corroding the solder. Check for a sticky residule near the Vertical IC indicating a leaky CRT seal.
Yes the vertical circuit will shutdown the set if theres a problem with the deflection circuit. This model has a history of leaking CRT coolant on the boards near the vertical IC destroying the solder and actually eating through the circuit board. Check the area near the Vertical output IC for signs of coolant leakage or solder cracks.
Check the electrolitic capacitors in the vertical section for leakage or dry condition. The vertical amplifier IC may also be defective and check for the solder joints around the high power resistors as well.
You might be able to take care of it yourself,you are corret when you said no vertical sweep,if you can identify the vertical IC it will be easy,you are looking for loose conections but by now it might have a bad vertical Ic and it needs to be replaced along with the safety resistor that power the IC,the ic should be mounted on a heat sink and the resistor should have low resistance,very straight forward repair and while you are there make sure and check for overheated areas and loose conections specially in the power supply , horizontal drive circuit and convergence IC's.Be careful you still have high voltage witch can be dangerous.
