    LG 47LF66 LCD TV Screen Issue

    Hi all

    I've got a LG 47LF66 47" LCD TV that has a screen issue shortly after switching on. Initially the screen goes black with 2 vertical dotted line then the screen goes to a cross hatch pattern. Still has sound. I'm thinking a faulty T-Con board. Any ideas (see photos).

    Many thanks

          Could be panel. I think that the main board on these can sometimes cause a similar effect - there's a tech bulletin that advises some ferrite beads be replaced on the main board.

                  Dynabook Satellite Pro C50D-B-100 - BIOS Issue, Black Screen
                  by wizard13
                  Hello everyone,

                  I am experiencing a BIOS-related issue with my Dynabook Satellite Pro C50D-B-100. When I power on the laptop, the screen stays black, and there is no response from the system. I suspect a corrupted BIOS.

                  I have checked the forum and the available documentation but could not find a solution specific to my issue.

                  Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
                  by Ryan.man
                  Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                  My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                  This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

                  HELP - Contrast/brightness issue with subtitles on screen
                  by cloudy
                  Hi everybody
                  Since day one I'm having an unpleasant contrast/brightness issue on my Asus laptop.
                  Basically while watching movies, if subtitles appear on screen, the contrast or the brightness of the entire screen increases a lot (not sure if it'is brightness or contrast), disturbing the viewing of the movie.

                  Last year I replaced my screen because got damaged and this contrast/brigthness issue persists. It happens only on the laptop screen, in fact If i plug an external HDMI screen the issue does not occour on it.

                  It occours both on ubuntu and windows...

                  Samsung UE48JU7000 screen issue after backlight replacement
                  by ScHAmPi
                  Hi all,

                  Because of two bright spots and a couple of dark spots I decided to replace the backlights in my Samsung UE48JU7000. See attached photos:


                  I thought all went well, but after full assembly and testing it out it turns out not all is fine. The backlights are completely fine but I have some weird issues on the right half of the screen. Since I didn't really touch the T-CON board (apart from taking out the ribbons of the display and reconnecting them on assembly) it would be weird that the issue is with the T-CON board... But based on the behavior of the service...

                  iphone XS turns off when press on screen.
                  by smic717394
                  Hi,

                  I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...
