[TechAssist] Re: Magnavox FP5230W104

I have taken the lens off of all the crts. I can see the phosphor coating on 
the face of the tube just fine there is nothing growing in the coolant of the 
red and green crts.and the snowy raster is clear when turned on. There are some 
traces of algae in the blue coolant, but I have seen worse without causing the 
symptom that I have. I am going to take the fluid out of blue crt and clean it. 
That will confirm one way or the other whether the amount of contamination is 
causing the problem or not.

Seen this a thousand times, it's always the fluid. Take the screen off,
look directly into the tubes with a flashlight and the set off, if the fluid
is not clear then it's contaminated. Compare the left or Blue tube (looking
at it from the front) to the right or red tube, they should look the same.
You can't always tell with the green tube because most of them have tinted
lenses.

> I posted this a week or so ago. It has very dim green and blue and very
bright red crts. I have replaced the green crt bd with the red bd and it is
still very dim. Checked the voltages on the crt bd that are marked and they
are all normal. Adjusting screen controls has no effect. Could use pdf of
main board. Most every thing is on it, or the crt generic part number.
> Don't work on many of these but this main board looks a lot like one
that I worked on a year or so ago that Magnavox wanted $700.00 for. No, I
didn't buy it, I repaired it.
