Re: Baird jo47.
Im not sure what your next steps are then i guess either find another main board really cheap that matches your panel make etc or try a eeprom change but theres no gaurantee i guess its either of them i wonder if it could be a lcd panel issue? i just dont want you wasting your money on parts that may not be at fault.

Just asks for confirmation then powers down, when I power it up again same scenarioLeave a comment:

Re: Baird jo47.
no idea too be honest have you gone into shipping mode and looked whats available in that sub menuLeave a comment:

Re: Baird jo47.
Maybe it is shipping mode? im sure ive read something about this doing a reset.Leave a comment:

Re: Baird jo47.
The only settings in the factory settings sub menu are shipping mode, aging, factory channel and ssc adjust. Cannot find reset anywhereLeave a comment:

Re: Baird jo47.
Go into factory setting if I remember the reset option is there.Leave a comment:

Re: Baird jo47.
Sorry I cant open the picture of the service menu ? Same board as mine so you might not have done it right. Also the Psu is fine its the mb for sure.Leave a comment:

I attach a photo of the caps that I have replaced, the two that are together (ec9 & ec10) had obviously gone, the other 3 (being ea3, ec2, & ln2)Attached FilesLeave a comment:

Re: Baird jo47.
i just wounder you had replaced 5 caps where they are ? and you didn't mentioned on VDC reading did you measure them if they are fit enough to support the main boards video process ??Leave a comment:

Re: Baird jo47.
im not sure myself lets see what the others think a factory reset may of sorted it but i cant find any information regarding this starting with the basics do all of the power supply voltages test ok etc.Leave a comment:

Hi Vince,
Many thanks for your advice, I'll leave the replacement eeprom on the back burner for now.
As for my next step...... I'm totally lost, where would you suggest that I go from here?

Re: Baird jo47.
In the PIC it says cv109h v1.1 where mine is a v1.2, would that make a great differenceLeave a comment:

Re: Baird jo47.
your link looks like that firmwares for a lg screen looking at the panel sticker in your picture its a cmo screen
or this from ohms supplies
http://www.ohmsupplies.co.uk/JO47-BA...GRAMMED-EEPROM for cmo screen only
please note though this may not be the issue with your tv so its up to you if you want to try it.Last edited by vinceroger69; 06-16-2016, 02:19 PM.Leave a comment:

Re: Baird jo47.
i wonder if this is a gamma ic problem? i know reece had one a while ago on a 47 in set although was a diffrent baird model number so maybe newer.Leave a comment:

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...
