I got this Tv in the shop today with no power, no backlights, and no sound. The customer said possible lightning strike. Voltages were not there on the PS and no response on the remote so I ordered the whole kit. I put in a new Main board and PS when I plugged it in I got a high pitch squeal from the transformer on the PS. I sent the whole kit back to SJ. Would a bad panel cause this? I've fixed this noise with cap kits or a few bad diodes nearby in the past so I'm hoping I just got a bad kit from SJ.
