Have you done any work before using a soldering iron, multimeter, capacitance meter or oscilloscope?
I would suggest to check the vertical section of the TV and you will more likely find a defective vertical amplifier IC.
The part markings should LA7837 or 38.
Let me know if you need further assistance.

Flay back tv mitsubishi model cs40507


Mitsubishi has offices in Brazil. Apparently, they are out of the consumer TV and consumer entertainment business for a number of years now.

With the phasing out of CRT television sets, I have my doubts you will find a flyback unless you can find a scrap TV of the same model as yours. You can also try eBay or others like that to see if you can find this part.

Mitsubishi cs40507 blown zener diode


It should be at the back cover, just where the model number is. If you have the TV open, it may also be found inside, maybe on or around the tuner area.

TV vertical height-Mitsubishi Model CS 35505


If the height has dropped down, you need to first find out why. Most likely there is a bad capacitor in the sweep power supply or the vertical output section. Good Luck

Mitsubishis TV Problem


have a Mitsubishi TV 1993. Model CS-35301. The problem is that there is a white line that is running through a blank screen. The sound is fine just no picture. Have you heard of "Vertical Collapse?" I would love to save the TV. Hi nothing to worry just minimise brightness to avoid screen burn. "Vertical Collapse?" means one bright hor.line in the middle of screen. this problem can be solved 1 check vertical yoke connector or wire loose 2 check supply to vertical section which normally comes from EHT transformer check components in vertical section or print loose regards thanks

Vertical rolling


Does you set have PIP (picture in picture)? If it does then the PIP module has a bunch of capacitors that have gone bad (dried out and leaked) causing you to loose vertical sync. Vertical synchronization is what locks your picture keeping it from rolling. Even if you don't have PIP then still you have a vertical sync problem. The set would have to be checked by a tech to find exactly what's happening. Stargazer
