Re: Baird jo47.
Maybe have a play with the Lvds settings first before ordering an epprom. Also have you got an image of the service menu please ?Leave a comment:

Re: Baird jo47.
Also noticed that two settings are set to "off" position, they are:
ssc miu and ssc lvds
Is this correctLeave a comment:

Re: Baird jo47.
Hi and thanks for the reply.
Although I don't know if it would make much difference, the screen on this unit is CMO.
I've managed to get into the menu (source 2580) but unfortunately there is not a reset option, only thing available is "shipping mode".
I was informed that I more than likely have corrupted firmware, and was told to look for a bin file. I have found one which I will attach, however I am not 100 percent certain that it is the correct one, not to mention that I require a pointer on how to flash it as there are not any usbs on the unit.
So any help and advice I will greatly accept!
Regards
Ben.Leave a comment:

Baird jo47.
I have This TV, all of a sudden it gave me problems getting out of stand-by, (red light would just flash away).
So I replaced 5 of the Capacitors, Now the unit switches on from stand-by quite happily.
However, Now the screen appears to be extremely bright pinkish white. Can still see the image displayed on screen, the picture seems like a negative.
entered Factory Mode (source 2 5 8 0) no eprom reset option there,
so where do i go from here?
Any help/Guidance will be greatly appreciatedAttached Files -

This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.
Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today.... -
I am trying to repair an LG split AC indoor unit, which does not start and gives a CH05 error code.
This indicates an error in the communication between the outdoor and the indoor unit.
The outdoor unit is fine, so the problem is the indoor PCB.
The indoor unit is an LG PC09SQ NSJ (3SNM09JA2FA), and the PCB has the following type number: EAX35907219-1.2 (see photo1)
I changed optocouplers ICO1X & ICO2X and the NPN transistor S9013 which drives optocoupler ICO2X (see photo2), but this did not remedy the fault.
Does anybody have the schematics of this board,...02-01-2025, 12:55 PM -
Hi. I got a Vizio with no power or standby, and won't turn on with remote or button. I checked the voltages on the connector and all read 0.00V or nearly 0(0.050 ON/OFF pin). None of the pins are labeled STB for standby although I do see some 5V pins. Other than the obvious standby led, which isn't coming on, is there a way to check for standby voltage on this PS. I'm trying to see if my problem is the PS or mainboard. Some Vizios I have fixed with no standby led me to think it was the PS but it turned out being the mainboard. Any experience with this set would be greatly appreciated. -
Hi all.
I started a thread while back regarding TV power supply standby circuitry as it is something I am not quite on top of.
SMPS theory and function is becoming more familiar, however the standby part is still a bit of a mystery.
Anyway, a friend has this TV with the above mentioned power supply board which has no standby voltage, nor any other voltages leaving the board.
The mains AC comes in fine, gets filtered and rectified with power is on the main filter cap as well as the transformer and drain pins of the ICE3B0665J, but that's it.

Hello everyone,
I'm turning to the Badcaps community to help me troubleshoot the radio Rx card from my (old) garage door opener. While I could just ditch that card and replace the whole system, I first would like to understand "why" it suddenly stopped working, because that's just how I am wired...!
Some basics: the receiver works on a 30.875 Mhz frequency. Yes, I'm aware this is not in use anymore in a looot of places. It does not use any rolling code, it's just a regular dip-switch code that you have to set up on both the receiver and transmitter. The receiver...
