Substitution Of Transistor
An IBM CRT Monitor came in with no power problem. After checked everything i conclude that it was only the horizontal output transistor C5280 that have problem. Since i could not get the original part i put in C5411 as substitution. I burn in test the Monitor for couple of days under high resolution and the result was it worked perfectly okay. If you are repairing CRT Monitor then please jot down the part numbers and who knows one day you shall use it.
