When we first turn on the TV, the astar logo (blue) on white background comes on the screen for a blip, but then the screen goes black. Was working fine one day, the next day this problem arose.

Re: screen goes black immediately after astar logo screen...

Astar 30" LTV 3001 ....These TV's have a cooling problem that causes premature electrolytic capacitor failure. De-solder and Test all the 2200uF-25v, 3300uF-35v and 1000uF-10v caps in the power supply (center board, back of TV). Use a good LCR meter that will read 3300uF or better, Replace all bad caps with 105c rated caps. If you don't have an LCR meter, replace all the mentioned caps on the PS. If fuse on board is blown, also replace the F9222L regulator IC chip. Mounting a small cooling fan on rear of TV over the PS will help keep your new caps from failing again. This requires holes in the stand bracket and the rear of the TV, power can be supplied from a 14V source near the bottom of the PS board.

Why does my KD-32FS170 32" Sony Trinitron screen have blue hues

If you turn all of the color out of the TV, the picture should be black and white. If that picture is not a true black and white picture, the TV will produce a color picture that has that behind it. It takes the proper mixture of red, green and blue light to produce white. This is something that is done inside the glass picture tube.
In your case, one color (blue is stronger) and the others are weaker.
It probably had not been used for a while. SOMETIMES, the weaker colors will get stronger with use. Adjust the brightness and picture controls to get the closest you can to a black and white picture, and then add the amount of color that seems right to you. Use the TV and hope for the best. It will improve, but 2%, 10%, or 50%; I do not know. The proper repair is to replace the glass picture tube, which is not an option at this time. So, turn it on, play games, and HOPE for the best.

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock. Be careful !!! Stargazer
