Just, don’t go out of your way to find out. A couple of tests can be performed to confirm that it is dueto beam current: The kids willlove the color effects. Pill bottles, film canisters, and plastic ice cube trays come in handy forsorting and storing screws and satasheet small parts after disassembly.
All this will do is allow you to rule out either theregulator or the horizontal section.
This is enough to be potentially lethal under the wrong circumstances. If it does, then there is probably a low voltage regulatorproblem – bad capacitor, resistor, or chip. This doesn’t mean that every one of the capacitors in your TV need to bedischarged every time you power off and want to make a measurement.
These are activated each time the CRT is powered up cold by a 3 terminal thermister device or other controlcircuitry. There you’ll findspecially educated people and the speed of the assembly line is a lot lowerthan usual.
If the TV quits at about the same brightness level, overcurrent protection is likely.
The deflection circuits must be synchronized and phase locked to theincoming video signal. Interaction of the electromagnetic fields of the deflection systems may result in one or both displays jiggling, wiggling, or vibrating.
Then, turn down the bias controls for blue and green sothat you have a pure red raster. Where there are two adjustment knobs on the flybacktransformer, the top one is generally for focus and the bottom one is for G2.

Wait a few minutes for thefilter caps to discharge but stay away from the CRT HV connector as it mayretain a dangerous and painful charge for a long timeuse an ohmmeter acrossthe various diodes in the power supply. These are becoming increasingly sophisticated.
However, note that the discharge time constant with these may be a few seconds. A storage scope or digital scope might be desirable for certain tasks but is by no means essential for basic troubleshooting. This will be the worst case. While off, you should get VAC. If power is controlled by a hard switch – a pull or click knob, or mechanicalpush-push switch and this has become erratic due to worn contacts,replacements are available but often only directly from the originalmanufacturer to physically fit and where applicable have the volumeor other controls dayasheet in.
They include a line cord and momentary switch. If more or less a decent picture with minor hum bars thenit could be the regulator. Try a larger one first.
However,the most likely parts to short are easily tested, usually in-circuit, withan ohmmeter and then easily removed to confirm. Heat buildup takes its toll on electronic components. There are very few situations in whichan isolation transformer will hurt. A Variac can be followed by a normal isolation transformer. Dstasheet not, just usethe raster in a darkened room.

You cancompensate for that with datasheet brightness control, which in effect willlower the VKs. If there is a question, unsolderone side of each diode and check – should be in the Megohms or higher inone direction. The horizontal sync pulse from the sync separator locks the horizontal deflection to the video signal. Next, slowly decrease the field to zero by backing straight up across the room as you hold the coil.
With TVs, the main filter capacitor is nearly always on the mainboard.
