Question about Sony HMD A220 17" CRT Monitor

1 Answer

Toshiba CF3566A I have a problem with above referenced set. It was dead except for a faint "ticking". I found a post in this forum by "pasty" who advises the following: "Common for the horizontal output to short in these models is a 2sc3892A which usually shorts because of a 10 uf 160V filter capicitor on the primary of the H drive transformer deteriorates & distorts the waveforms causing H out transistor to overheat & short" I have located the Horizontal output transistor which is located at Q404. I replaced it. The TV now powers up (no Ticking noise) but shuts down after 10 to 15 minutes. I can NOT locate the above referenced 10 uf 160V filter capicitor. I have found one such cap on the power supply board and is identified as circut # C416. I dont think it is that one. I dont know where "the primary of H drive" is that the solution post refers to. Can someone please identify it for me by telling me on which board and what circut number it is? I am almost home free on this...I welcome any assistance. Thank you, The Bandit

    Sorry, but I was unable to follow your instructions because I did NOT understand them.
    But thanks anyway.

Follow the diagram, the base of the hor out should go to the secondary of the hor drive transformer, and going to the primary circuitry you should find a transistor, a small transistor, look for its collector and you should find a filter capacitor, may not be the same value but it is the filter capacitor.

No post to bios on new pc build

FIRST....... Make sure you remove the stock thermal compund (pasty/sticky stuff) from the bottom of the heat sink as well as from the top of the cpu.........

Second APPLY some ARCTIC SILVER 5 compound-ust a thin coat of it over the top of the cpu......use an old credit card.....keep it ff the sides and bottom's important not to use too little tube will do anywhere from 3 to 5 CPUs...!!!
(stock thermal paste/thermal compunds......**** BADLY and can cause a cpu to burn up)

reseat (properly) the cpu and carefull

Now make sure you're 24 pin or 20+4Pin Power connectors are connected, as well as your fans..........disconnect all your SATA Devices, and remove everything but the video card , CPU, and fans.......Now it should post (if all your jumpers are set correctly...........

IF it still doesn't post, remove the video card and reboot.

If it doesn't beep at all......... You have one of 2 things.........A DEAD CPU, or a DEAD MOBO
