Default Re: Help With Vertical Circuit. Capacitor getting extremely hot

So I found D407 was fried so changed it and i found another resistor for the feed and changed that, started the set up and heard deflection for all of a second before a crackle, burning smell and the tinyiest amount of smoke from the feed resistor then just the horizontal line.

did some checks and the frame IC is toast with a little scortch mark just above pin 4 which is a ground pin, the whole IC has continuity now along with every component in the vertical circuit and R408 has gone open. Cant remove the IC as my desolder pump decided to randomly disintegrate while i was removing the resistor the last time (never buy a €6 desolder pump on eBay )

Now i need a new Frame IC and possibly some other parts, in fact i might just order everything in the vertical circuit (that I dont already have new) and replace the lot and be done with it.
