Many thanks for your comments and inputs! The best way to discharge the very high residual voltage oin the CRT is to pull the mains cord off and keep the TV in off condition for a few minutes. Then take a screw driver, connect a crocodile clip wire between the ground and its blade and insert inside the anode cap. Better you wear gloves as an additional protection. Since current is very less, it won't be lethal, but enough to cause a burn or temporary pain upto the arm pit or more. I have experienced this shock a few times inspite of all the cautions that I take. Especially from the tank capacitors!

Thank you Engineer Parasuraman for showing great dedication and a big commitment to the Jestine Yong website. Thanks again for your detailed direction of CRT TV repair. ln April 2024 when I started reading your CRT TV repair articles I understood close to nothing but I knew there was much to learn about electronics and electronics repair. So I continued reading more articles until I started catching up. That helped me to make a 25 inch Toshiba CRT TV that was dead to come on by replacing its HOT(2539), a 1500V ceramic capacitor and a diode-looking like resistor. Though the TV has pincushon, which if found difficult to deal with, then motherboard change will be the way to go following your easy illustration. Please always give precise instructions on the high death trap voltages and how to effectively discharge the voltages before any repair. The younger generation may be unaware of the lacking danger. Lastly, I always appreciate Alberts comments but I know he no longer sees CRT TVs, anyway thanks Albert.

Another incredibly and professionally done crt repair
with unexpected nice surprise added in the very
interesting article "fixing-es-china-kit-in-crt-tv"
dear Parasuraman! Thanks for taking the extra time to
make this!
It will be a very important learning experience for me
since my knowledge in using these universal replacement boards and fixing old crt sets is still very limited!
No doubt that now also many other readers on Jestine's
blog will be able to enjoy and prosper from your
extraordinary knowledge in using these universal boards!
