deflection has gotten better. you said it outside for awhile, now you can sub a cap underneath. just make sure its + to + and - to - until you find the bad one. Theirs a bad cap in there close.

Yeah, the next cap in line is a 35v 1000uf. I have a 35v 1500uf. Ok to use?

well after i looked the picture again that's not the vert section. coming from the yoke there should be 2 wires one yellow and one green. follow them down to the chassis that will be the vert section. same thing find the bad cap.

At the yoke, I got two sets of wires. One set says yoke H which as brown and red. The other set is yoke V and it's brown and black.the brown and black run to the caps we changed. I do have a yellow and green but they come from the board on the gun.

https://elektrotanya.com/rca_chassis...wnload.html#dl hey i found the service info. with thosehttps://elektrotanya.com/rca_chassis_ctc203_training_manual.pdf/download.html#dl sets the tuner ground did not have goo solder from the factory. that cause the e prom go bad, but first check the voltage on the vert side only see if what the reading is. plus do a ohms check on that side. i leaning towards bad vert chip. the e prom was just for a few chassis. the bread butter of shop. give that a try.

I'm not good this multimeters except when using for home wiring etc. I took the board to a guy and showed him what u said. He said he can't check it because he doesn't have an oscilloscope etc. I have my meter but not sure of where to set it or where to test.

i am going to be honest i don't you to get hurt. there's not much in the vert section. 90 percent is in the output chip. i hate to say the parts cannon, but you half deflection and the bottom has a nice picture, so do not give up. the tough dogs are more rewarding to fix. there's about 10 parts in the circuit. you replace the 3 caps and has the pulse from fbt. cap from the ic was replaced and the 3rd was to. that's the next thing other checking resistors and diode.

Going at this one piece at a time, what should I check next?

Ok I found the cr14501 right next to the caps we replaced. I have trays full of new diodes. Is there a specific number or something I need to look for yo get a match?
