Use care when handling the wires or connectors of the inverter circuit. Damaging the wires may cause a short. Protect the panel from ESD to avoid damaging the electronic circuit (C-MOS). 10) It is recommended not to exceed 1 hour of Power-On nor Burn-in period with LCD panel face down condition, in repair activity.

6. Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer. 7. Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. 8. For safety reasons, repairing the Power board and/or Inverter board is prohibited. XBR-49X835D...

If a cold-water pipe is not accessible, connect a 60- to 100-watt trouble- light (not a neon lamp) between the hot side of the receptacle and the retaining screw. Try both slots, if necessary, to locate the hot side on the line; the lamp should light at normal brilliance if the screw is at ground potential (see Figure B). XBR-49X835D...
