Question about Televison & Video

1 Answer

Rgb colors are not registered - we did the perfect focus which is available in the menus - but it's still off. The centre of the screen seems fine -- the right hand side has the red going to far right, and the left hand side appears to be putting the blue too far left.

Philips Projection Screen TV Model PTV915 Horizontal Alignment


Problem solved, needed to get the universal remote i was using set up with the proper code. Once I did that I was able to use the remote to set up the single & multi-zone Red & Blue Alignment.  I also pulled the back plate off and manually adjusted the RGB focus knobs. It seems to be working just fine now.
Thanks to all the other posts.

27'' RCA appears out of focus on the vertical Edges of the Screen


I've seen this on many computer CRTs as they age past 6 years. I would imagine that the gun alignment is out. Are all the colors (RGB) fuzzy, or is it hard to tell?

1. Sometimes, extreme settings of contrast or color (usually to offset low output from aging CRT) can appear to unfocus your screen. Adjust color/contrast down if they are maxed out or close to highest setting/pot level.

2. A very likely culprit is unshielded speakers are too close to the screen. If this is the cause, the speakers' magnets distort the part of the screen closest to them (sides), and it will get better/worse as you move the speakers away/closer to the TV. If there are not magnets near the TV, and degauss function does not fix problem ('89 TVs have degauss?), see #3.

3. The focus can be set by adjusting the flyback transformer. As an experienced electrician, you should know about the dangers of messing with the insides of the unit.

If this fails, you might have other bigger issues. I'd suggest a nice trip to lead reclaimer if so. I'd say 19 years is quite a life for a CRT.

A lot of green tint in the picture


Hi, what you do is unscrew and take off the grill, take off the black board behind it. You will see a little box for adjusting RGB you will adjust the screen rgb to get the tint to go away and have a perfect color then you will adjust the focus for sharpness. (reset the tv to factory settings before doing this so that your tint, color, brightness and everything else is in the middle.

Colour misalignment and focus


Inside of the tube assembly, there is a cooling liquid. This could be a job to change, and then re-adjust everything. It is also possible that on top of this, there are problems with the convergence and bias control circuits.

Typical repairs can run in the area of about $400 to about $800 depending on the amount of work and type of parts required.

Personaly, I would go out and get a good Plasma or LCD TV at this point!
