LG 42LE7500 stuck at splash screen

[maxvalutech]

Scored this along with a 60PV250 from people who advised "picture stuck on little one sound but no picture on the big one". So yes this one is stuck at the LG startup screen and won't go any further. Does switch on/off with remote and set controls, receives commands but doesn't react - so I suspect eeprom (nand flash on this I think). Have been able to download new firmware to USB but can't get it running to upload. Have tried freeze spray, menu menu on set and rc but no results. Anyone have any knowledge how to get beyond the splash or kick start this set??

A couple of days ago on this site someone successfully unbricked their set with instructions from

Probably needs a reflow.

One guy did a preheated oven at 385 fahrenheit for 10 minutes but who knows how long this type reflow will last.

OK and thanks for advice. Yes the boards in these look weak and subject to heat flexing I would think. Obvious main board problem so went over it all with heat and then gave it a try. The set fired up and I was able to tune it in, check and reset all settings, and give it a good run. When turned off to standby and then restarted backlights did not come on, however this morning it started normally so took the opportunity to update software which took as described. Now for a few days testing and here's hoping.

These are instructions for Samsung not for LG

The reset is applied to the chip, not specific for the make or model, once you find the chip and the pinout then you can try doing the reset procedure.
