Question about Hitachi 50UX57B 50" Rear Projection Television
Either the blue CRT lamp, or the ballast board powering the blue lamp must be replaced. Before replacement the part must be tested reading high voltage out from flyback transformer for blue CRT. For safety reasons the test must be done by a trained person.
If I was in your shoes I would hope the problem being the flyback. CRT for Hitachi projectors are quite expensive. The flyback can be repaired by a technician working at component level. Part is about $40, but it may be out of stock.
CRT Lamp Blue DP33KA 46 PRT ASSY ( B)
Flyback (out of stock)

The clicks are discharges that the high tension are causing on the blue crt because the tube itself is defective and must be replaced The flicker is caused by the spark when it occurs the voltage on the tube drops and that lowers its luminosity.
As a last hope take out the back cover, access the tube, try to locate the spark and see if you can shift some pieces to stop it from happening.
