    I get tiny red dots in the screen, especially during the night scenes when it's dark, or when I turn the TV on, and the screen is still blank, you'll notice those same red dots right before the program comes on. What's causing those dots to appear?

The convergenceboard is on the fritz. Located on the small signal module, there are two convergence ICs that will need replaced as well as several resistors. See a tech to repair this! Please do not adjust the screen colors or turn any potentiometers. It does not sound like you are in big trouble yet! Thanks for asking!

Tv cloudy and faces are red


TV needs CRT coolant replaced, once this is done the focus and color level of each CRT needs to be adjusted for optimum picture. expect to pay around $300 good luck, Julio at Millenium TV , Las Vegas NV (702) 736-1091 milleniumtvsvc@gmail.com

Color


see if there is a "default" option, if not set everything back to the middle, if the colors are still off you sure its not the convergence?
most big screens allow you to change "color temperature" it's like a default adjustment for 3 different brightness levels.... ie...COOL, WARM picture will show obvious changes in brightness

Color adjust


Greetings!

Adjusting the picture tubes is a scary proposition, but since you have already done it...
The easiest way to balance the gray scale is to turn the color all the way down on the set. The next part is easier with two people if the screen controls are on the back of the set. This is the part you saw that has six small knobs on it. There are control for the focus of the red, gree and blue and for the screen level of the red, green and blue. You will want to adjust the screen controls in an effort to get the picture black and white (this is why you turn the color down), hence the term "gray scale". Just make slight adjustments, take your and be patient. It will take some time, but you will get your picture balanced back out in time.

Hope this helps!

Need to find out how to adjust color


im curious why you think you need to ajust the color do you have red screen? or missaligned colors?
If your B&W images look okay (bright and dark areas), either films, ads,
or turing the color off, you shouldn't tinker with grayscale
adjustments. You'll really mess up your set. Haven't seen many
complaints about 'red push' with Pioneers, but that may be the problem.
A further check would be the decoder test on the Avia disc. Also visit
http://www.hometheaterspot.com/ and search the Pioneer section for
similar complaints.

Red drained out of picture


The red transister on the CRT socket could be at fault. there is 3 transisters on the socket check for the voltages on all 3. If the red is high unplug the socket and see if it normal if not the transister or circuit feeding has a short. If low the same case seneral applies and a resistor feeding the transister is defective or the transister itself is at fault
