I want to get this but I think its water damage tab bonds, don't know if the t-con is on bottom or top of this one. Any one have a pic of the inside of this set.

Yes, it may water damage tab bonds.
remove FPC 1 by 1 from tcon to panel. if right side half picture get blank. it is possible water damage tab bonds. care fully clean oxide with smooth brus and check for burnt track there.

The TV shows a black screen with no image.
TCON ribbon connectors were disconnected individually for image and there was no half image even.
Later both ribbons were disconnected and TCON voltages were tested.
12V, 3.3V, 1.8V were seen present but VONE signal reads 0V.
There is also a short to ground in this circled inductor.
Is this a TCON issue or something else ?... -
Hi,
I have this problem with my Sony 55' AG9.
It flashes 4x.
I have found the service manual, and seems it is the TCON.
Before I buy a TCON can someone check the vid?
Thanks in advance!... -
Hi, hoping for some views on this one which I've not come across before. The TV generates an image that has 12 noticeable bands across it. The image is still there and accurate, but the colour (or perhaps the brightness) changes gradually across each band which creates a noticeable 'step change' at the edge of each band. Given it's a 4K TV with 2160 rows of pixels, I'm guessing the 12 bands correspond to 12 gate drivers of 180 rows each. If this guess is right, then perhaps:
a) all the gate drivers are malfunctioning the same way (which seems unlikely), or
b) the Tcon board is malfunctioning,... -
I got lucky that when I got home and was about to get some ice out of the ice dispenser I hear and see water running down the outside of the ice dispenser what the heck is going on here
At first I thought that the ice dispenser mold was cracked so I brought a new ice maker because this one has been in there for about 10 years now
Well I put the new one in and wait and I wait for the water valve to open and let water in no such luck well there is a way to check the function of the motor and the water valve on this ice maker just need a jumper wire “L” to... -
This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.
I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...
