Hi there,
I see a couple of posts related to the troubleshooting of similar TV. The one I have is acting slightly differently and I'd love your help.
So it has the 5 blinks. Previous owner got a TCON, no luck. Got a new Main board (though he didn't do the USB firmware update), again, no improvements.
I see 2 posts that are relevant:

Hello from France,
mon2 kindly advised me to post a thread to ask the question(s) I'm concerned about. I'm new to the forum and I'm looking for practical courses for troubleshooting pc motherboards especially laptops in Europe, if possible in France. I have been a computer network system administrator and a corrector of administration modules for automated programs under Unix. But I really miss the practical "ops" side of troubleshooting. So I would like to start from the beginning: 1.8V, 3.3V, 5V and 19V tests for example, etc...
Do you think this is feasible for me? I... -
Hi all,
I'm asking for some ideas/guidance on where to go next with my troubleshooting efforts.
A history of events so far:- TV was dead. No signs of life, no standby light. Nothing.
- Replaced power board. No results. Same issue (oops)
- Replaced main board. Local supplier only had a variant board in stock. As far as I can tell, this board is used for the TV's smaller cousin (LC-32D59U). It has the same printed part number, but different sticker numbers.
- I had to buy a new pin header, and solder to the new board to connect the display signal cable.
- TV now enters

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... -
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...
