GPU could not tested panel in stand alone... yours issue at MB. if the panel buffer boards didn't suffer from liquid damage at buffer boardsb

Hi Diah.....Was this message meant for me? if so I'm confused!!

on the tcon , near the input connector between 2 caps there is an inductance, small, check it both sides for voltage, i forgot to say it, where do you have soldered the 12v wire? in saw on fuse but there is no fuse so you had to use that inductance..

yes its
again this non T-CON, this is GPU circuit of early LM series.. later they installed it at MB, this why you will not find any Fuse of 12V. cause its going with 3.3V line too to operate FRC.. answers from others ignore its just fantasy ... who knows when he have this early version and later under hist hand.

Tcon is full of 7 converters as usual, so it starts as usual 12v then stepped down or up depends on the converter.. plus, the tcon asic is always the last prior the panel, it does not exist FRC after Tcon, THIS is Fantasy!

Hey D....Is this the location of where you mentioned, I'm guessing you meant inductor (inductance) and not clear what you mean "in saw on fuse but there is no fuse so you had to use that inductance." There are no fuses on the T-con or main board as far as I can make out..
I measured both ways and all I'm getting is a nominal 9.8mv

Hi Diah....Whats your feelings on this issue, as...if I'm correct, there seems to be a difference in opinion which I seem to be stuck in the middle!!

Diah can you also explain what you meant #34??

Sorry, the idiot who projected Android obliges me to the automatic corrector, i mean, the inductor it's maybe used instead as fuse and is toghether an inrush current limiter, i don't know, so in your screen stand alone test, where do you put the side of wire for injecting 12v to tcon? 9mv has no sense, i trust you do not see a thing so! I do not remeber my old post, but toghether with the jumping wiire to tcon you need also to do 2 jumpers on the power board to enable full on PSB and backlight, if you aren't able i tell you how, i need PSB output table schematic if there isn't

PS: jump 3,5v to PWR-ON and to DRV-ON

If T-CON sees any faults (low resistance or short circuit) on the output voltages for the panel, it blocks them, disconnect one cable from T-CON and the panel (from the T-CON side) and turn on the TV and see what's wrong with the image, then reconnect the cable and disconnect the second one and also check the image (the image will appear on at least half of the screen).

Hey Lotas...I tried your advice again only this time I left a little longer than previously and not sure if this makes any difference but this time the screen changed drastically as you can see from the attached..

if the panel dint have any liquid damage on the buffer boards , then refllow the chip on MB IC9300

Davi if this helps I found the schematic for the PSU..

i don't want a schematic, only the pinout of connector..
what you show on the last pic is normal for lg screens, them don't show image if half connected, only bars, my opinion screen is ok but wait for the test

Davi... As requested pinout connectors. If you need anything else that I've missed then let me know.

With regards to....PS: jump 3,5v to PWR-ON and to DRV-ON, these already have a supply.....
and you say "enable full on PSB and backlight, if you aren't able i tell you how, i need PSB output table schematic if there isn't"
The backlight has always came on with no problems?

I do not like your way of participate to this forum, i asked for a picture means obvioisly a clear picture, i already told you what to do on the basis of what you produce (text, photos), if you decide to do something let me know.. otherwise it becomes a very boring discussion.. bye..

Hi Diah......When you say reflow the chip, I'm guessing using flux, what temp and for how long roughly? Need to ask as never actually tried before!!
