Re: Sharp LC-70LE
looks like bad panel. open it up and disconnect one side of t-con that connects to the screen. then reconnect and do the other half. if it is panel, you will have a good pic with one of the sides connected but the opposing side will give you a distorted picture.WHY CAN'T PHILIPS USE PHILLIPS HEAD SCREWS? -
Re: Sharp LC-70LE
check your cable connections to all cards. I don't think its a panel but it depends on the history.... how did the tv get to its current state.... all of sudden, lightning/power surge, etc? my guess tcon or main board or cables between.Comment

Re: Sharp LC-70LE
Might try flexing panel and see if it changesI assume no responsibility for any stupid suggestions I might post.Comment

Re: Sharp LC-70LE
Thanks for your replies, I did remove one side of t-con flex at a time and I did get a good half image but it had some horizontal lines in a 6 inch portion of the screen.Comment

Re: Sharp LC-70LE
it is likely you have the "standard bad panel / tab bonds". Lots of posts on this forum. The tv can likely be saved by finding out which side is bad and removing the tabs on the bad side. Read thru the thread on these types of set.Comment

Re: Sharp LC-70LE
That sounds just like when a Sharp has a bad LCD panel driver and has code 2-5.....
A tab bond fix, while harder, isn't a sacrifice like the shorted panel driver issue is.....
But, with that panel driver removal procedure in another thread, the tv was working like nothing happened.

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.

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... -
I have numerous Creston TPS-2000L touchpanel home automation devices, which incorporate a Sharp LQ5AW136R panel. They all exhibit the same fault. They are about 10-15 years old.
The fault can be seen in the attached photo. Basically the displays are all washed out, to be point of being unreadable.
Clearly it's an issue with the panel. But my question is whether it's just aging related (e.g. all the pixels in the LCD wearing out) or whether it could actually be a more specific component (i.e. one capable of being individually replaced). I've seen suggestions on other... -
49UJ6500 LCD panel has a lighter band on top when first powered on. Goes away (or gets much fainter) after TV on for a few min. After powered off for awhile and power back on, same band appears. If powered on immediately after powering off, no or much fainter band. Running the latest firmware.
Disassembled the TV and lifted the LCD panel during testing. Band is on the LCD panel (can see the band on the panel as I lift it slightly) Backlight is perfectly even at the top edge. Double checked LCD panel alignment in the frame and is perfect but since band moved with the panel, its on...
