Re: No blue color with Toshiba Model # 50A61

The tv needs troubleshot to find out why the blue is missing.
Start at the blue tube and make the voltage and waveform measurements
on the crt socket and work your way back to where the OSD, convergence
test pattern, and video are combined before being sent to the three
picture tubes.

Not sure what this means?
Call out a qualified and trained technician to perform a proper and
safe diagnosis and repair on the set.
