Vertical collapse L301 is burned in half. What could have destroyed it, and what is it? (the markings are gone). Thanks

    Yes, you are correct. I have an open resistor, blown inductor coil and two shorted zener diodes. I'll also replace the IC just in case. Thanks

    OK, I have replaced these parts just to have the set work fine. For about a month. Then the same parts were blown again. Replaced them again and got about three weeks service. What could be taking out the vertical circuit? Thanks

I think L301 is an inductor coil supplying B+ voltage to the vertical output IC, also a diode and resistor are associated with this circuit. Most likely the vertical IC has shorted causing L301 to open up. The diode could also be shorted. Stargazer

Isuzu kb. We replaced the clutch an we bleed the system. It works for a while but then the fork gets stuck an looks like the cylinder pushed to the max. What causes that??
so if the the slave cyl. moves to max and the clutch does not disengage, then the throw out bearing is destroyed, ,first it burns up, seizes or collapse to a shell of nothingness.
the hyd. clutch is self adjusting, so there is no calibration like on cable or rod systems...
if its bled right the slave moves full distance.
so.... T/O bearing is GONE , end of the road.

I HAVE A HALF SCREEN. BOTTOM HALF LOOKS GOOD TOP HALF HAS WHITE LINES WITH A BIGGER WHITE LINE SEPARATING THE TWO. IS THE PICTURE TUBE GONE OR IS THERE AN ADJUSTMENT I CAN MAKE? TV IS A RCA F25645
This is commonly known as a vertical deflection problem. It cannot be fixed with an adjustment, but requires changing some electronic components. Namely the vertical output IC (integrated circuit) and in addition usually in this model a resistor which may appear to be burned.

I have an older model Hitachi 32" ultravision CRT tv. the video just collapsed into a thin horizontal line (about 1/4"). Video is fine. Any help would be greatly appreciated. Thanks.
TURN IT OFF AND DO NOT TRY TO USE---if a thin line left to right in middle of screen it is vertical problem---the set should shut down but even seconds count here--this can burn a mark on all three picture tubes instantly and it is permanent.

Problem if small line left to right in vertical circuit.

Let me know what you know and I will try to help--I know these sets very well.

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
