Simple problem. In all likelihood, The Vertical Output IC has failed. It will be TDA 8177. Replace. Or, it could also be that the Supply to that IC has failed. Unless you are competent in Solid State repairs, do not try this by yourself. get a professional Technician to have a look.IC should not cost more than 15-20$ pluch Tecnician fees.

Hello bashlort, The increase in voltage may be to some circuit loading being removed this is a sign that something may have increased in resistance or something may have opened in the attached circuit. Have you taken any voltage measurements in the video section of the set, if not check the voltages on the pins of the video processor IC and follow the connections up to the CRT socket, be sure to pay special attention to the focus and screen grid voltages. If those are ok check the voltages in the horizontal section including oscilloscope measurements for drive signals. Please inform me of your findings. Thank you, Shuttle83
