To determine the cause, you might have to take out

the Horizontal Output Transistor.

There can be two points , where you can check

the Supply B+ to your Flyback

a ) Direct measurement on the Collector terminal

pin on the PCB ( after you have extracted )

b ) Direct measurement on the 200V line and post

the voltages.

Next after noting it down,

You will need to unplugged the yoke

You will also measure the voltages later

When you reinstall a new one ( But do not , yet

till I know the B+ you are having )

when these is connected and unconnected,

These is it for a while , while I would be suggesting

more, after I have known the B+ that your

Flyback is having.

These are your possible causes:

a ) capacitor parallel to the Horizontal Out Transistor

b ) bad yoke

c ) partially shorted Flyback

d ) fake Horizontal Output transistor

e ) Over driven Horizontal output due to

HDT and onwards to the osc.

( from the jungle IC )

f ) High B+

h ) High Voltage has exceeded its limit.

    • here is where you can measure B+

    The unit will run, if there is no Hor Out Xsistor

    There will be about 215V on D411 if the



    ( H Out Xsistor connected of course )

    • you may have to check on these circuits

    if your B+ is higher than Normal

    • and you might also have the CRT Board disconnected

    from the CRT Socket , only when troubleshooting.

Dead set!

First, locate the horizontal output transistor. This is found very close to, or next to, the horizontal output transformer (also known as the flyback). The flyback should be on an aluminum heat sink, or on the side of the metal chassis. Disconnect or unsolder two of the three legs of the transistor. Measure it with your meter, or plug in the set with the light bulb attached across the fuse.
If the transistor is shorted, or the light bulb doesn’t glow bright anymore, replace the transistor and plug back in. If the light bulb glows bright again, you must replace both the flyback and horizontal output transistor simultaneously. In some cases this will fix the set, but sometimes there are multiple problems with a set.
Go to where the flyback is, and start measuring the diodes and capacitors on the flyback itself. If you don't find any shorts there, it could be a shorted vertical output IC, a shorted sound IC, a shorted disc capacitor in the Hi Voltage/sweep circuit, or in rare cases, a shorted capacitor or tuner.Feel free to ask and post whatever the result of your troubleshooting..

Hope this may help;
