Re: Sharp LC-52LE830U Lightning Strike No Standby

Well, looks like I spoke too soon. I'm not sure what's going on with this one. I was trying to set the network back up and suddenly the picture on the screen shrunk to that of a 42" TV, then it cut off entirely and went into a loop of trying to turn on repeatedly until I unplugged it. This one has turned into a pain in my backside.

If it's still powering up, try to access the service menu and do a complete reset, possible a small incompatibility between eeproms.

I got the tv to turn on with that board but there was no wifi. I ordered a second main board and received it today. I installed it and now I get a 2-3 code. No +3.3v from power supply, though it will still turn on with the other board. I'm about to give up on this one.

Seems a good deal of these mainboards are always bad, no idea why they go bad so often. My theory is someone gets angry with their faulty TV and smashes the screen, parts recycler assumes boards are good. This often appears to be wrong.
