      You should post this in the TV section.
      https://www.badcaps.net/forum/attach...0&d=1521562008
      There are labels for the pin of that connector, please put down the pin name and follow by the Voltage reading so we can EASILY see what it has for each pin when TV is OFF and when power switch is activated.

              Sharp Aquos LC-70C6400U Half Screen Dark
              by scubacamper
              I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.
              Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
              when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display...

              Sharp Aquos Lc-80LE757U flashing Sharp on screen when plugged in
              by sefoster
              I have a Sharp Aquos LC-80LE757U that randomly made a loud popping noise when when watching TV one day. We found that the fuse blew and the thermistor. We ended up replacing the entire power supply board and have also replaced the TCON board. Now as soon as I plug the TV in it lights up and has the Sharp logo flashing on and off of the screen. If I unplug the ribbon cable from the TCON board to the main board I get the 2 long 5 short error code. Any ideas on where to go from here? We've tried resetting it but nothing has worked. If we plug it in and let it cycle through the flashing of the Sharp...

              by Joekhoe
              Hello all, I'm Joekhoe, a newbie here and ask your masters permissions and solutions for the problem i'm facing at the present.

              I am in the middle of working on a SHARP Smart TV model LC-52LE835X from my customer, which totally dead and there's no output voltages at all at the output pins even though i have replace some of the components the output voltages remain the same with 0 volt.

              The replacement as follows:
              1. IC7905 : TNY264PN (first found exploded)
              2. Q7915 : BT169D (exploded too)
              3. IC7901 : 1608B (controller ic)

              Powersupply has all the voltages - Monitor still no power
              by Capacitorial
              Hello guys,

              I have a Philips 240B7QPJEB. The monitor seems completely dead.
              I opened it and measured the voltages of the powersupply. I found that a mosfet was dead and replaced it.
              On the connector, that goes to the TCON board, all voltages 15-19V and 5V are present.
              The small connector on the left of the PSU has two cables with 18V and all the other have 0.2V. It connects on this small connector on the left ontop of the panel. I guess the backlight? Seens fine I guess.
              The weird thing is, that the Power LED is powered over the TCON board.
              On The TCON...

              Is this white-washed screen caused by a faulty T-Con board or panel? Sharp Aquos c70le735x
              by thesharpfella
              Hello esteemed gentlemen. I have owned this LCD TV since 2012. The only repair was the replacement of the PSU a few years ago. Apart from that, no issues. Recently, all was working fine until I switched on to see it appear as so. The day before it was working fine. There is sound. Could this be a T-Con board issue? If not, what could it be? Thank you.
