I have a PN-LE701 that turns itself back on almost exactly 65 seconds after being turned off. I have done a hard reset, factory reset and updated the firmware by USB, all to no avail. I called Sharp and they said they have experienced this quite a few times and just replaced the main board. Once, a factory reset corrected the problem but only once. Any help appreciated.

Re: Sharp PN-LE701 turns itself on
if none of the usual works, look over the solder joints on powerboard very closely, resolder any that look a little suspect being careful not to bridge anything, maybe also suspect the start up capacitors by the connector on powerboard where the cable from powerboard to mainboard is located, example of bad solder joints there in case anyone needs it: https://www.google.com/search?q=bad+...ih=607&dpr=1.5

Re: Sharp PN-LE701 turns itself on
Originally posted by TVnovice2 View PostWell we got fooled. When the problem first appeared we changed the NAND chip and that did not solve the problem so after much thought and testing we found the "new" NAND was not working and replaced it with another new chip which solved the problem.
How did you replace and program the NAND chip? Did you just solder on a blank NAND chip and flash the firmware?
Thanks!
