SONY KV29C3D - black and colourful horizontal lines (pic in)

[Arc]

Hi!

I have a problem with my old Sony Trinitron 100Hz TV. It's strated to show up sort of those colourful and black lines, running all over the screen. What I find it strange is that the PIP function works just fine, without any of those weirdo things. First there were just little black lines, but then the screen got more and more fuzzy.
Sometimes, when I turn on the TV, the screen would be fine for few hours and sometimes it gets from this black mashup to a normal pic quality, so I wonder, whether this is a repair I could do by myself.

Thanks, any help would be greatly appreciated.

And post photo from the internals only leaving the lid.

2)- Can you read a service manual / schematic ???

3)- Is your house suffering from High humidity ???
(seems that the crt socket have some internal leak of focus voltages)

4)- Are these noisy lines sparkling even in still picture mode
(100 HZ Have still picture mode, check on remote keuboard)
