If this is solid, then there could be a high voltage drift butthis would be somewhat unusual without other symptoms like arcing sincethe HV is nearly always tracks the low voltage supply.

The average projection TV has about twice as many parts as its direct-viewcounterpart. Most problems occur in the horizontal deflection and power supply sections. Then, turn down the bias controls for blue and green sothat you have a pure red raster.
If it is a totally solid state chassis, then there is some component – daatasheet capacitor in the power supply since it affects both picture and sound – thatis drifting with temperature and needs to be located with cold spray or aheat gun.
2sv3346 to a strong channel or play a good quality tape.

If they are fuzzy, especially in bright areas, then focus may dqtasheet be adjusted. This is risky – you can blow things up if not careful including yourself. If the bulb lights at full brightness, youknow there is still a major fault.
Failures – usually shorted diodes – are common. The high voltage section is prone to breakdown and arcing as a resultof hairline cracks, humidity, dirt, etc.
The fuse should not blow with the transistor removed. Irrespective of the cause of the tilt, sometimes it is possible to loosen the 4 typical CRT mounting screws and correct the tilt by slightly rotating the CRT.
A colorbalance problem in this case means either a failure of this circuitry or a CRTwhere the emission from the 3 cathodes is so unbalanced usually due to onebeing much much weaker than the others that compensation is not possible.

Are you a perfectionist? Then,increase the color control to obtain the desired degree of color saturation.
A disadvantage is that you will not get optimumsharpness and peak brightness from your picture tube. It will not damage the capacitor due to the current pulse. Most of the time you will get away withputting it in series with the AC line.
Just be sure that it is also safe! Modern sets do not generally have any linearity control but you may findthis on older models.
Read, understand, and follow theset of safety guidelines provided later in this section whenever workingon TVs, monitors, or other similar high voltage equipment. A nearbylightning strike or EMP from a nuclear explosion can also affect purity. If any of these are bad, they will need to be replaced with flameproofresistors of 2sc3364 same ratings though you can substitute an ordinaryresistor for testing purposes.
You always wondered what that wall switch was for that didn’t seem to do anything and you flipped randomly: If it does not, there datasjeet still a fault present. The flyback generates mostof the other voltages used in the unit and provides an isolation barrier sothat the signal circuits are not line connected and safer.
However, even if the access procedure is known, get the service manual or Sams’! What I have inmind is something about as powerful as a refrigerator magnet.
If you find a blown fuse, remove it and measure acrossthe in-board side of fuse holder and the other should be the neutral sideof the line.
IC from a special line-derived voltage. There may be others as well but without a service manual, there is noway of knowing for sure. TV shuts down with dark picture or when changing channels: The IF section may be in either place. And usually this 2wc3346 wherethe single deflection circuits are distributed to the 3 CRTs.
