This set does have a history.
Originally, about 7-8 months ago, it had an error code but you could force the power supply on (via those button codes) and I reset the error codes and it worked for that length of time.
It came back with the power and OPC light blinking twice and I suppose the power light once more. You could get the set to power on (ch- and vol+ (might be other way)) but it would only have a steady power light. There was no backlight, image, or sound. The voltages checked out OK so we ordered a main.
That has come in and now has a different set of problems. Instead of resolving to an error code, it just cuts on and clicks back off and on after about 10-15 secs for as long as you leave it plugged in. To a degree it power cycles and the buttons on the set have no bearing to its function.
But, I finally did get it to trip an error code (power and OPC blink once and power twice more) but I do not know what this means. The SM on elektrotanya does not have the blink codes meanings.
My question is, does anyone know the meaning of the code or at least another SM to reference that perhaps shares the same chassis?
All the voltages are in spec. The inverter boards are not getting an ON command and the error line is LOW. The TCON 12v (from psu) is not there but I noticed that there was a PNL-PWR (panel power?) pin on the main harness which was LOW, which I presume is the ON command for the 12v to TCON.
Any tips for these Sharp TVs and would it seem a likely argument that the main I received may be faulty?
LOW in this text is meaning nominally 0vdc.
