How do I fix a Sony TV that starts then screen goes blank


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Tv gone green/blue and sometimes red in top right corner


If you have a Sony rear projection LCD TV then you have a failing optics block. LCD TV's are not affected by external magnets like CRT TV's were. The optics block issue will only get worse and needs to be repaired by a technician.

Sony KP-57WV600 rear projection


sounds like bad CRT, some of these sonys have had defective CRT issues, usually all will come and go sooner or later (all 3 bad), you can pull the speaker grill off(either 2 1/4" screws on bottom or 6 1/4" on back sides) and pull off the Crt box cover (2'X3' piece) and lightly tap the CRT's with tv on, if they flare or get colored streaks in pix they are bad, CALL SONY 800 # and complain, also could adjust G2 (Screen control for color) for short patch. Will need new crts.

CHECK ANY MAGNETIC MATERIALS ON THE CORNER OF THE TV.IT HAPPENS DUE TO MAGNETIC MATERIALS ONLY. SUPPOSE IF IT IS THERE KEEP AWAY FROM THE TV. AND THEN GO TO THE MENU OPTIONS AND SET AUTO DEGAUSSER ON.
