Some sets no longer have any vertical size adjustments and depend onthe accurate regulation of the voltage to the vertical output stageto control vertical size.

Discharge to the metal frame which is connected to the outside of the CRT. We are all spoiled today.

However, even if the access procedure is known, get the service manual or Sams’! Don’t overlook these really simple things when troubleshooting your vacuumcleaner – or fancy electronic equipment!

Heat buildup takes its toll on electronic components. Some of the extra parts are essential for projection because CRTprojection tubes require dynamic convergence. It not, the outlet is defective or the fuse is blown or the circuit breaker is tripped. In some cases, there is no regulator.

The tuner components are usually quite reliable unless the antenna experiencesa lightning strike. During flyback, the current is turned off. In a TV or monitor, if 22sc3346 are removing the high voltage datasheeh to the CRT to replace the flyback transformer for example first discharge the CRT contact under the insulating cup at the end of the fat red wire.

There may be a doxen or more each mostly affecting a region around the edge of the raster. There are two areas which have particularly nasty electrical dangers: Therefore, we have the following functions: The flyback secondaries provide the remaining voltages. The PTC thermister heats up, increases in resistance, and smoothly decreases the current to nearly zero over a couple of seconds. There is an external tilt control which may be misadjusted. TV turns off after warming up: On some sets, a half wave recitifier is used resulting in a single wiggle or hum bar.

Rock yoke from side to side to converge the top and bottomof the screen. Spread the leaves of its prongs. In the old days there used to be 3separate potentiometers for 3 G2s, now there is generally only one. If these test good, use an ohmmeter with the set unplugged to measurethe horizontal output transistor.

A Variac tm is not an isolation transformer! However, for most dramatic impact, a darkened environment may bepreferred. On older or cheap TVs with a knob tuner, this is usually mounted to the front panel by itself. With a too high cutoff voltage the cathode electron emitting surface will wear out eatasheet soon. A storage scope or digital scope might be desirable for certain tasks but is by no means essential for datssheet troubleshooting.

There will be some HV on the back of the circuit board on the neck of the CRT but although you might receive a tingle but accidentally touching the focus or screen G2 pins, it is not likely to be dangerous. I thought a TV signal was a TV signal. Use a soft brush like a new paintbrush and a vacuum cleaner to carefullyremove the catasheet up dust.

However, if the displayis unusable as is, then using a small magnet can do no harm.

Problems with SCR based regulators: Dead TV with periodic tweet-tweet, flub-flub, or low-low voltage: There are usually several connections to theCRT and cabinet: CRT high voltage also part of 2. This is what is expected when the equipment is operating normally. Just, don’t go out of your way to find out. There is another very simple explanation that is sometimes overlooked: This capacitor is between. The detection circuit could be in the power supply or horizontal deflectionoutput circuit.

The ohmmeter reading should be fairly high 2sc346 well certainly notless than ohms – in at least one direction.

Unplug the degauss coil as this will show up as a low resistance. Again, always double check with a reliable voltmeter! Fuse blows or TV datasheeet up when sync is disrupted: Furthermore, while the shock fromthe Daasheet can be quite painful due to the capacitance of the CRT envelope, itis not nearly as likely to be lethal since the current available from theline connected power supply is much greater. Sometimes, just letting the problembounce around in your head will lead to a different more successfulapproach or solution.

TV shuts down with dark picture or when changing channels: Complements to the maid. For more information on TV technology: Some TVs do not have anyisolation barrier whatsoever – the entire chassis is live.

Newer Sony monitors have this don’t know about TVs – a most wonderful addition.
