Re: Sharp LC-60EQ10U no display code 3-1
This thread applies to me
https://www.badcaps.net/forum/showthread.php?t=70302
Voltage on the big caps is 400V and panel 12V looks good on both of my ps boards.
I disconnected all four ribbon cables from the tcon and the backlight came on. With the right 2 connected, display is good on the right side with left side white. Guess there is a panel fault on the left side. Need to rip off the left side tabs.
Update: Ripped off the left side tabs and tv is working! Symptom was tv did not turn on. After multiple attempts, would flash 3-1 error code. Power supply panel 12V tested good on the regulator which can also cause the 3-1 error code. 3-1 code based on service manual pages on previous thread is an initial communications error. Some post indicate a bad regulator can cause this.Last edited by neilc6; 08-15-2019, 08:19 PM.Comment

Removing the side tabs worked for my issue. Tv would not turn on unless the far left tcon ribbon cable was removed. Found out about the tab removal here on badcaps. I could literally see the screen get better as I pulled the tabs off. Much appreciated!Comment

Hello.
I am dealing with a Philips TV, 43pus7505 and is stuck on boot loop.
So I ordered a used CPU board, and now I have wired picture.
I think the problem lies in display option code. According to SM, the command for setting
display code is 062598 + MENU + 032 (032 is written on a label on back of a TV).
But as soon I press the menu button TV jumps in menu. Can someone please tell me what I am doing wrong,
or can I manually edit option code in SAM. -
Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
Hello there,
I have a SF314-41 motherboard that i bought impulsively recently, the problem is that i only bought the motherboard only, nothing else. When i tried powering on the board with 19V (soldered on the DC IN port), and then shorting the pin 1-2 of the keyboard, the board is turning on (as indicated by the fan), however it seems like the board is displaying on the internal display as connecting to a display on the HDMI (external) does not display anything.
I tried connecting a USB keyboard, the keyboard is powered on, however pressing numlock do nothing (supposed to toggle... -

Hi! I have a Razer Blade 15 2022, with a RTX 3060.
One day, while using Linux, the internal display suddenly stopped working.
On Windows, it says that the internal GPU has stopped working (with error code 43).
I have tried removing the coin cell and the battery, and replacing the RAM, with no success on fixing anything.
I'm looking for directions to fix this problem, and, first of all, I would like to be able to access the BIOS and change some settings (which is currently impossible as it is always shown on the internal display). There is a setting...05-29-2025, 07:01 AM
