SEMP TOSHIBA TV2999KMS
This TV arrived sound just blinking and turning off! After putting it to work, it didn't show video at all and tsound was also a very loud leak on the flyback pacifier! After changing everything without success I tested the burnt tube! If all voltages are ok, this tube! I had the deflector coil and put it to work with the kinescope plate, if it gives a pink light in the tube, you can discard it I put a 29 inch panasonic tube of the same type ready!
