ECN Forum Forums General Topics of the Trade Voice - Data - Video Discussion electronic parts for my toshiba 2939DB

Going off on a tangent somewhat, but in the old tube/valve sets the line boost probably presented a somewhat greater hazard -- Anything between about 500 and 1000V but able to deliver a current many times greater than that available from the high-impedance EHT supply.

Mind you, some of those old vintage sets which derived their EHT direct from a mains transformer instead of the LOPT could be absolutely lethal!

I used to be able to get Sam's Photofacts at my local library in Cleveland, Ohiu, USA. That saved me alot of money fixing TVs, stereos, Et,c. You could easily spend 20+ USD acquiring the technical docs for you set. The high voltage on my 27" Panasonic is spec'd from 26-28KV. Your 29" set is most likely higher. Are you aware that you can discharge the CRT and put the set aside and still get zapped by many thousands of volts when you come back to it with the new parts. (If you don't leave it shorted or discharge it again.) It probably won't kill you but consider filing a flight plan before taking off. I have no clue what those parts are but some form of alignmet might be required after you replace them. Many of the sets today have secret service modes that are only described in the technical docs. Why don't you just ask "some one who is involved in the electronics", how much they want to do it for you?
