My Samsung projection TV no longer shows the color blue.

This also affects every other color that involves blue. Any advice. Any estimate on how much the repair will cost?

not sure of model but you might want to remove front bottom bezel off and check for leakage onto crt neck pcbs from one of the picture tubes.you will see corrosion on these pcbs.

cory is right, on many samsung rear projection tvs the coolant will leak from the crt lens on to the pcb, thoroughly wash the pcb with isopropyl alcohol, check for any corrosion on components and replace any showing damage, replace the crt and realign, not really a task for a novice as it is very involved and will only result in a working set in 50% of cases.
