PCN5425R Fading in and out
No It is not the picture tube.
First, I would suspect a bad solder connection (cold solder connection) to find this problem hit the side cassing to see if the picuture goes away or comes back.
Another way is take the back cover off and tap gently on the boards with something not conductive or your hair would look like mine. The most commond section is power supply and neer the Horizontal flyback transformor.
The horizontal transformor look at it, it's a big greyish darty little thing about 3" x 4" and stand up about 4" with a big red wire going out of it. Don't touch it, it has very high voltages, just look what it done to my hair I'm telling you don't touch it along with it's red lead's. Just look to see if it is arking if so replace it.
When you have convegence problem , it is mis aligment of the colours in the genmentry aligments.
I would suspect more in the power supply section.
