1084S monitor repair

Hello all, I have a 1084S monitor that's taken ill.

I was using it one day, and it was working just fine, and then it turned off. It hasn't turned back on since. Pushing the power button only gets me a high-pitched squealing sound; the screen doesn't turn on, and neither does the power light. Hoping that it would eventually wake up, I let it sit there, making the squealing sound for about five minutes, but it determinedly stayed off.

I don't have the expertise to fix it myself. I have all of the proper tools, but I don't know what to do. If anyone has encountered this exact problem before, and can describe the fix in very clear and detailed steps, that would be most helpful.

Alternatively, is there anybody here that knows how to repair it? I would, of course, be willing to pay for shipping both ways, parts, and labor. Since international shipping would probably cost more than it's worth, I'd prefer you to be located in the U.S. Just send me a PM and we'll talk.

It sounds like the line output transformer has burnt out, and probably the transistor with it. You can still get these so it is repairable, but be warned, that part of the set is where the highest voltages and current are and will possibly kill you if you touch it. You need someone who knows what they are doing to repair it for you.

Yeah, line output transformer is quite common problem. EDIT: Check also all transformer solder joints.

Easy (non-dangerous) first step is to desolder horizontal output transistor and check if it is shorted. (zero ohms between collector and emitter pins, both directions). Then turn it on without transistor, if nothing happens (no squeling sound), it is confirmed horizontal section problem.

Look in the Springfield, MO phone book for "TV Repair" and take it in to be fixed. A CRT monitor lacks the tuner aspects of a TV and is easy for the repairman to get into tip top shape.
