Question about Standard (CRT) Televisions
Hello! Our TV is a Toshiba and it is 8 years old. It is 36 inches and the picture keeps going out. Sometimes it shrinks to a smaller screen and sometimes the picture goes out completely. The sound works fine. Is this something that is fixable?
If the shrinkage is just the top & bottom then it is relatively easy/low cost fix. Most probably, a capacitor in the vertical section is nearing end of its life. This would be the biggest of the bunch and would be something like 47uF/50V.
If however, the shrinkage is on all four sides, then it is the master power supply that is at fault. Chances are the main B+ is getting low which cold be caused by the big filter capacitor or an erratic regulator. This is not a simple fix and would require the services of a qualified professional.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
