Nice work. I hope your eye heals without appreciable vision loss.

This is the TV my Grandparents had in their living room. Brings back some memories I remember it ended up having a green cast on the picture.

23:23 every single time an electrolytic capacitor reads higher than spec on a capacitor meter of that style , it means its leaky...because the meter charges the cap and measures the time it takes and uses that value to calculate capacitance...if its leaky it will take more time to charge , creating a fake higher value....a brand new 10uf thats fresh and hasnt been in the shelf for years will read about 9uf... a 100uf will read around 90uf 47 will read 45.... the more leaky it is the higher it will read... if you dont have a proper high voltage old school leakage tester then there are chinese testers wich cost less than 20euros that test multiple components including caps , and they test very accurately for esr, leakage and capacitance.

33:10 when it comes to electrolytic caps its alwas the smaller form factor ones that go bad...the large cans can last way longer than the small tiny ones. my theory is that since they contain more electrolyte they take more years and heat cycles to dry out completely.. other thing: maybe youre supposed to move that jumper around to center the vertical, maybe to compensate for component drift... and you should use a test pattern because maybe its not a centering issue but a linearity problem on the bottom...a circle pattern would help... just burn a test pattern dvd and play it if you have an rf modulator... hope i helped

I've had the exact set for 5 years, initially it kept breaking down and after fixings it few times and finding that the problem was always another capacitor I recapped the enter set (except one cap in one of the if cans) and it never had a problem since then.

The Sony Trinitron & Toshiba Blackstripe Series of Televisions, were some of the best TV's, back in the late 1970's & early 1980's. They were quality products, & long lasting.

I worked on a TV once and the circuit board was covered with white cat hair stuck down with cigarette glaze. That was my worst experience.

Ew!

My 1983 Sony kv1331 recently died on me hopefully i will be able to get it working again as its very low hour set. Yea the CRT is very strong like new strong so even if I can't repair the set i will keep the tube.
