    What exactly is your question? If TV is working fine then why you need to see CRT and deflection yoke coil inside TV?

    I don't see how this could happen unless someone opened your set and reversed the windings on the yoke coil.

The CRT is the Cathode Ray Tube, it is the complete internal screen assy for your old style monitor or television.

On the rear neck of the tube is a large set of coils which makes the tube work.

It controls screen size , positioning and shape

To set it up you need a lot of experience and a signal generator

Possible failure of the VERTICAL SECTION of the deflection circuit. It is possible that the areas related to the vertical circuit is checked , check for weak capacitors near the output vertical drive. Also a faulty vertical coil- deflection coil- can result in half picture.
A vertical signal test can confirm.

When the screen goes dark there is a blue halo with rays radiating out from it.

this is likely caused by a misaligned deflection coil on the blue CRT or in the blue deflection amplifier circuit or a defective deflection coil assembly, you may be viewing a inductor ring, posibly due to arking internal to the coil these are the most likely faults

Only bottom half of the screen shows, also i need the service menu. How can i get to it. Thanks in advance!

I'm not familiar with this model of Sony, but the picture shows a CRT TV. If this is so, your vertical deflection circuit has gone bad (it's nothing to do with the service menu). This can be caused by bad capacitors in the vertical deflection circuit, a bac IC, bad power supply to the IC, bad solder connections, or a combination of any of the above. In this case I would use a scope to test the circuit to see where to start from. You can always do a visual inspection to check for blown or burnt parts and bad solder connections. Other wise you'll have to have a sevice person look at it.

Horizontal Line

you have a vert sweep problem. Probably the vertical output Ic the B+ going to the vert out IC or in rare cases the deflection yolk could be bad but not likly.

Ringing Noise

That ringing noise sounds like a deflection yolk or an on board coil is starting to sing as we call it. theres not alot you can do unless you find the source as the deflection yolf in the past we used to stick popcycle sticks into the yolk while in place and hot clue them to get rid of singing yolks.. But its onlty a temp fix. the best way to fix it is too replace the singing yolk. Now if its a coil it could be a loose winding on the coil and hot clueing the coil on the outside sometimes fixes thast too but in the end the best way was to replace the coil that makes noise.
