Sharp Aquos LC-32CHG2601 LED. Blue screen

[6BW6]

Blue screen, backlights OK, white LED starts flashing red after about 20 seconds and will not switch off.

Tried Tcon ribbon, Tcon fuse and re-set. Anyone come across this?

Thanks, Dave.

Here's one possible reset: Unplug the television.
Press and hold the "Channel Down" and "Input" buttons on the panel.
Plug the television back in while holding down these buttons. ...
Keep holding the buttons until the television powers back on. ...
Use the remote to navigate the "Service Mode" menu and select "Factory Reset" from the menu.

1) Holding the input button down is an impossibility - the set has a 'wobble stick' as I call em', up down and side to side for vol and Channel, press 'in' to toggle off/on.

2) "Service Mode" - also an impossibility with blue screen and no display.

" Sharp Aquos LC-32CHG2601" Can you please verify if that is the correct model number?
Also please upload the pictures of the whole backside of the TV showing all the boards and the screen shot of what is shown on the screen.

I've got 1.8 & 12V on the Tcon, the LED voltage is 48V, would that be right for this model?

Just a dull blue screen, the LED's seem OK when looking at the back of the panel, no menu or anything.

Here's the board

We need to see the whole backside of the TV showing all the board so we can see what it has.
How many ribbon cable between T-CON board and the LCD panel, two?
If it has two then what happen when you have it connected one at a time?

Re: Sharp Aquos LC-32CHG2601 LED. Blue screen

The Tcon connections comes from a bunch of wires to a inter connection board and then via the ribbon cable. here is a photo. https://ibb.co/x2K4j96

Removing them makes no difference, still blue screen with backlight and about 20 seconds before red led flashes continuous on a regular basis.... no spaces etc.

Edit
Pretty sure this is a Hisense set.... Sharp gave them the license to produce sets I believe. Sharp UK doesn't recognise this model. I was hoping to get a firmware update from them.

Thanks, Dave

It's made by UMC.

Re: Sharp Aquos LC-32CHG2601 LED. Blue screen

It has integrate T-CON into the panel.

Re: Sharp Aquos LC-32CHG2601 LED. Blue screen

The Tcon can clearly be seen and this is where I checked it's 1.8 and 12V.

Yes, I can confirm that UMC is the maker NOT Sharp, I understand Sharp allowed Hisense to use their badge. I just received a Email from UMC stating they can send me the firmware which I am waiting for. Let you know how I get on.

Well, I installed the firmware and brought screen activity, upon completion the set switches OFF and the LED flashed rapidly as per the instructions, at this point I unplugged and removed the USB stick as advised.

This took about 7 minutes as per the instruction.... after which the instructions said the update would take about 15 to 20minutes...... I got initialising in the top corner then waited and waited for at least half an hour.

All I got was the screen changing colours as stuck in the burn mode.... so I reckon we can exclude the T'con and the ribbon cable.

Thought I'd update.

Re: Sharp Aquos LC-32CHG2601 LED. Blue screen -SORTED-

With set unplugged, download firmware onto a USB stick, insert an plug set in - this takes about 7 minutes with the progress displayed on the screen.

After which the set will shut off - WAIT until the power button flashes rapidly, this took about a minute or so UNPLUG and then remove the USB stick.

In my case, when plugging back in the initialising circle appeared and the screen kept changing colours.... (Burn-in mode), but the instructions from UMC said to wait 15 to 20 minutes, I got sick of trying so I did the 'proverbial', unplug the set, with the the 'wobble' button on the back pressed I plugged in - Bingo, set is now back to normal.

Should you ever require firmware from UMC always gave the Model and serial number.

Holding power button while plugging in is a go to reset that works in a lot of cases.

Great, so it is working normal again. Please upload the FW so we can use it in the future and also your serial number.

Re: Sharp Aquos LC-32CHG6021K LED. Blue screen

I'm trying to upload now. I thought I'd corrected the model number it's a LC32-6021K NOT a 2601.

I give up, something went awry in the post in EEPROM dump didn't include the .rar file
