At first tv had sound but no picture. replaced a fuse (125v / 3.15A) that seemed burnt. Picture came back, but colors are seperated. Didnt touch anything but fuses.
Go into menu and with original remote call up convergence--either it has a problem(will not adjust) or you may with the remote be able to manually adjust the convergence back: sometimes if a power outage/surge it scrambles the convergence memory.
SOURCE: Toshiba 50A61 have sound but no picture - all fuses check okay
Not too many--if sound is developed from the set and not a surround system the set will blank the 3 picture tubes for a few reasons:
Voltages missing at the tubes (high voltage or screen voltages etc)
There is a loss of vertical sweep or horizontal sweep--set will do here this to prevent an INSTANT burn mark on all 3 tubes.
One thing you can try to look for is to see if the filament in each tube is lit---rather dim as 6.3 volt one---if lit the above reasons are your problem.
Without a meter, a schematic etc not much more you can check.
You should hear a faint whoosh sound when you power the set on--the high voltage coming up.
Testimonial: "Each tube is dimly lit, but I don't hear the whoosh - must be the HV is missing. I assume the black boxes with the HV wires going to the tubes may be the problem. Are these easily replaceable (screwed in) or soldered in place?"
