    You know that noise that comes on when turning on the monitor

    Ok I get  squelching noise when I turn the monitor on but no LED light.  I also do not get anything on the screen. Let me know if you can help thanks

    That part no. is from the working monitor as for the non-working one the part no. is C5302 I checked the diode test from C-E junction and it get a reading of about .4 volts Is there another test from another junction that I can hookup my meter to?

    The Horizontal Output Transistor from my old monitor is part no.  DE9704

    I have another monitor that has one can I just swap to into this one.  The part no. is different and I dont know if these things are interchangeable. Will that work?

    Whats a good site in trying to find a replacement for the Horizontial Output Transistor? thanks

    CRT monitor

    I forgot to ask  you on my last post. What value should I get when checking resistance on collector-emitter junction of the HOT?  Do I set the volt and the highest resistance scale?  Let me know

    Step down converter you say. Is that the same as the flyback transformer? Is there an easy way to check this part without disconnecting it from the board. As for the HOT what readings should I get out of it.  by doing the diode test I think getting the .6 volts is sufficient no?  What else...

    power on the usb frm pc!!!

    Go into your systems settings of your control panel then click where it says usb ports and you will see the current supplied for each.  I thing it was between 450 and 500MA

    CRT monitor

    It is a Sony monitor and I dont remeber the model no. I do hear it making a sound when it is turns on. The LED power light does not come on when I power it up.  The screen remains blank when I power it on.  As for the output transistor I do get a .6 volts across collector and emitter when...

    CRT monitor

    My computer monitor just went on the frizzs. So I decided to open it up and investigate. I do not see the obvious burnt component and also checked out the fuse if it was burnt. I put a voltmeter on the output transistor and I get around .6 volts which tells me that it is probably good.  Can...

    220V to 110V

    Can you tell me what site I can  find this step up transformer? Do I just wire it into the other transformer?

    220V to 110V

    ok upon further inspecting the unit it says that it uses 250V and 1 amp.  So where do I go from there? It looks as if the transformer is part of the whole unit and it cant be replaced.  Can I add something within the circuit to let it run at 110V.  Maybe a power transistor or...

    Repairing circuit board

    instead of doind all that why dont you just run jumper wires to whatever part of the circuit it was hooked up to.  In other words where it was broken off just take the wires and solder them into the traces where they were connected or find a junction point and solder it there.
