This is for a different model, but I had thin horizontal lines in red and had to adjust the tube for red. You may have a similar adjustment on your set.

Here IC specsheet:LA78041
Also replace the 100uf/35 volt cap on pin three of the IC and the two zener diodes connected to the IC. That is part of standard repair. If you don't replace the whole lot the IC may blow again.
Here the IC for sale. Cost is less than $5.

It sounds that the kit is a Chinese one. Check the voltage to all terminals of vertical output IC. Check and replace it. This is a common problem to these kits.
