Question about Sony FD Trinitron WEGA KV-27FS100 27" TV

1 Answer

G2 wire I ordered a replacement Sony 1-900-803-22 so I can solder it in where the old one broke off. I'll splice it in to the flyback G2 wire since it looks like it doesn't have a plug on the flyback end. I'll let you know how it goes.

    I haven't yet fired up the TV. I'll wait til I get my replacement spark gap wire and solder it in.

How do I fix a broken wore on the ICM


You'll have to carefully solder a length of wire to it in order to make a splice. Gonna be hard to solder, so see if you can wrap a piece of cold solder film around the stub and hit it quick with a mini torch. Have the other piece already wrapped in the solder. You can get a little bag of those cold solder pieces from a radio shack.

Hi. It seems that the g2 voltage of the picture tube is too high, resulting in a white screen, often with white horizontal lines. The g2 (= second grid) voltage is derived from the flyback high voltage. The voltage divider is mostly integrated in the flyback trafo housing.(including the adjustment knobs). A failure in this divider may lead to this defect. The static you hear may come from sparking in the divider. The flyback trafo is soldered onto the main printed cirrcuit board. Sometimes, one of the pins sits loose in the soldering pads.
Turn on the set and observe for any sparking around the entire flyback circuitry, and, or the flyback trafo itself
The screen turns black after a while, as a too high beamcurrent is detected. The set disables the flyback. Stand-by blinks meaning that there is a fault condition.
Be carefull with the high voltages. The flyback voltage is very high (20-30 Kilovolts !) and may be lethal !!

You will need some solder wick to remove the old solder. You need to heat up the old sloder with a solder iron and while its molten touch the solder wick to the solder and the wick will absorb the old solder. You will need to keep trimming the solder wick end so it will keep soaking up the old solder. Do that to all remaining pins on the flyback. The replacement flyback will not come with the high voltage wire attached so you will need to remove the wires from the flyback. This is accomplished by twisting the wire 90 degrees while exerting upward pressure. Instalation is the reverse of removal. Let me know if you need additional assistance.

Instead of taking the board out, I just soldered two wires to the old fl231 fuse on the underside. Installed a fuse holder with a half amp fuse. And I re-soldered all of the flyback points. My tv is working like new. thanks for everyone's help.

Unfortunately that's an indication of the crt going bad in a Sony.
You can turn the G2 voltage down on the flyback or have a tech rejuvenate the picture tube but either of these are only a temporary fix..
The flyback is the rather large transformer with a red (anode) wire coming from it and attaching to the crt. (looks like a suction cup).
There are two adjustments on the back of the FBT, one is screen (or G2) the other is focus. With the unit on turn the G2 counter clockwise just a little and the picture will get slightly less bright. That should stop the picture from blinking out - or doing so as often. But again, it's only temporary!
Good thing Santa's almost here... :)

Did you adjust the two controls on the new flyback? The top one is almost always the focus control and the bottom is the G2/screen control (brightness) If you adjust the G2 do it until the picture looks normal, too high and you will get retrace lines through the picture.
