I have model # CS26301 televison (15 years old). When I turn it on, I get a blue screen. It takes anywhere from 10 minutes to 2 hours for the picture to come on. It went to the shop and they said a board was bad. Which board is bad and how can I get one?

The problem is in the vertical section of the main board. Bad capacitors and maybe the vertical IC. If you are not inclined to be a tech you will have to take it to a shop.. I don't know what they may charge but I normally get $69- $89
Most tv's degauss themselves when turned on so turning off and on a few times might help. Leave about 15 minutes between on off cycles and keep on trying untill you see improvement. You could also get hold of an old tape eraser, plug that into the mains and starting from a foot or so away try to brush the badly coloured parts away without coming to close to the screen.
Where did you adjust the red and blue?................Did you remove the speaker grill cover and the access panel to get to
the screen control adjust? Do not adjust focus..........make
sure you turn down ( CCW ) the red screen control a little....
is that any better...........?...................T.
I will not bore you with advice which you cannot follow. (90 % probability, looks like the Blue Signal Video Output Transistor has become faulty). This is a very simple "fixable' problem for a Professional Technician. Should not take more than 15-20 minutes.Nothing you can do. Call for Professional help.
