Re: Sharp LC46D64U Power and OPC Flash
I tried the upgrade firmware but the TV doesn'T even try to open....it blink power at 1 sec
Its strange how I get 1 sec power light blink when I just plug the power and 2 blink/sec power light and 1 blink OPC light when I plug it while pressing VOL - and INPUT at the same time!

Sharp LC46D64U Power and OPC Flash
Hi guys
I am working on this unit for a couple of weeks and now I need your help!
So when I plug it nothing happen but the green power light blink at 1 sec.
When I plug the TV while holding Vol- and Input nothing happen BUT power light blink twice and OPC blink once.
So in the manual this mean: PS_ON DET_10V failure ''DET_10V (pin 57). UR10V or A9V is not applied.
If error is detected during operation, the power is turned on
again by interrupt handling (instantaneous blackout processing).''
I just istalled the Shopjimmy...Last edited by Icitte; 11-04-2018, 04:58 PM.

Mosfet goes from reading to OL
HI guys
I have a Toshiba Mosfet K3569
When I test it, the reading between D and S (after turning on) get from a voltage and getting higher until OL in an seconde or so. Is that a normal situation or a bad MOSFET?
All bad mosfet video I saw on youtube only show shortened reading between D and S .
Thanks
And sorry if my english is bad!Last edited by Icitte; 09-25-2018, 02:14 PM.

Smoke after removing fuse on LG 60PC1D
I removed the fuse from the Z sus panel to see if my problem will change and I saw smoke on the top right of the board. I didn't see from where it came from since my reflex was to unplug the TV
I serisouly doesnt understand how a board can work and smoke when a fuse is remove
Have any idea? Board is short?
thanks
p.s.: here a video from my problem: [url]https://www.youtube.com/watch?v=upipmbyyx1k[/url]https://I removed the fuse from the ...idn't see from...

3v diode test and good capacitance range
"Capacitance
Range 9.999nF, 99.99nF to 999.9uF, 9.999 to 99.99mF"
And I can get it for you for 109$CAD Re: Multimeter Replacement<br /> <b...ce range<br />

Re: Multimeter Replacement
I am really not a pro, but one thing I learned will testing LCD monitor is that it is important to have the diode mode with at least around 3v. because some mosfet need that much voltage to get activated and tested!
Mayby some pro may confirm this
