well if your not to bothered about it being an origional diode, then this will do as a replacement

go to www.littlediode.com and search for BY713
(it wont let me post a link to it)

(and in the uk and in stock too)

BY713 datasheet is here, its voltage is up to 20kv which is more than enough for b/w monitor!

hope this helps!!

On the diode the end with the blue band you solder onto the wire that goes onto the tube cap, the other end you solder to the transformer where the old burnt out diode conected. you might want to find a plastic tube that will slide over the new diode and before sliding it over put some of the silicone sealent recomended in the other thread first then slide it over. if no plastic tube around then try something like a bit of a bic pen! it will add some mechanical strength too and stop it getting broken off

see the first paragraph of the datasheet, silicone is the modern insulator!

still got same issues though ??

plugged it in , crossed fingers and whoopppie i have neck glow , no arching .

job done :)




however with either chassis in cab and in either cab , the screen remains white ? i have no game play , no game sounds , doesnt coin up yarda yarda yarda :(

reset line issue perhaps which you mentioned ???? .. seems weird happening on both cabs ?

as to v5 voltage should i have it bang on 5.0 or more ??
