FAULT:      6 or 7 blinks from LED
            Does not proceed - no picture or sound
--------------------------------------------------------------------------------
DIAGNOSIS:  Test with Y sustain (SC board) unplugged; control and power
            If this passes, check MOSFETs on the Y sustain for short, the SMD
                ones most commonly fail.

            image is unstable on one or both halves. Colours may also be wrong.

            Does not proceed - no picture or sound
--------------------------------------------------------------------------------
DIAGNOSIS:  Freeze-spray SMD ceramic capacitors on MC301 and MC302 on P board.
--------------------------------------------------------------------------------
FIX:        Replace such capacitors near the TEA-chip as they commonly fail.

MODEL:      TX-26LXD80 + many other Panasonic using 26" Chi-Mei panel
--------------------------------------------------------------------------------
FAULT:      No picture or distorted image on power up
--------------------------------------------------------------------------------
DIAGNOSIS:  Twist TV frame slightly and gently. If picture comes back, suspect
            the tab bonds.
