This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. MAY BE INTERMITTENT, SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24.

Popping, snapping sound


Hello fulby2001,

Have the CRTs checked for grid to cathode shorts. The CRTs do this (pop and crack) when they have Grid Cathode shorts. I would advise having a qualified TV technician do this for you.

Thank you,

I hop this helps

Problem with sylvania 6413TC 13"tv


This is a runaway high- voltage condition. When the TV turns on, the high voltage goes out of sight, causing the snapping or popping sound. Then the high voltage shutdown circuit takes hold, and the set cycles on and off repeatedly.

Popping noise


Does the " popping" noise come through the speakers or from the TV chassis ? If it is coming through the speakers you could have a bad solder joint somewhere in the tuning circuit. If it is a snapping sound coming from the chassis, then you probably have something arcing in the high voltage circiut. If this is the case then you should have it checked out since this can cause other parts to short shutting down you set completely.
