By the way, these transistors are 2SD1453 compatible?

No. If you replace that part, you need to go with the same part. That's why it's one of the shaded parts on in the service manual. You can find the right part on eBay, but really you should only be considering replacing other parts after you've solved your vertical problem, which is unrelated to this part.

I would also check part tda1170 that it's not overheating because of high current draw from a bad cap or resistor
Be save crt byte
