1)Check PC boards for CRT coolant leak.Look closely at the
signal board and the main/power PCB.
2)Check any/all fuse devices in power supply
3)Let me know your findings....T.

perfect focus functions are based on service mode setup...or factory settings. if the alignment of these setting are loss then the unit wont perfect focus. does the unit have a complete loss of convergence. a complete loss of convergence indicate possible failure of convergence amps.

SOURCE: perfect focus reads "no sensor data"

SOURCE: Samsung HCN5529W 55in Rear Projection can't Perfect Focus

hello What you have is a convergence problem. There is 2 modules inside your set that aligns the colors to have the same geometry and superposed . It is a common problem in rear projection tvs ,
You don`t have to worry about your blue tube , i`m sure it is perfectly fine, it just needs to be aligned through the convergence circuit.
Most often the problem is with those convergence modules that are faulty and need to be replaced.
Hope this will help good luck

You have either a bad convergence IC on the power supply/convergence board or the whole board is bad and needs to be replaced along with doing a Full Convergence Alignment by a very experienced tech.
