Baird jo47.

[benjamin.d.bird]

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 appreciated

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.

Re: Baird jo47.

Also noticed that two settings are set to "off" position, they are:
ssc miu and ssc lvds
Is this correct

[ReeceyBurger123]

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 ?

Re: Baird jo47.

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.

Re: Baird jo47.

In the PIC it says cv109h v1.1 where mine is a v1.2, would that make a great difference

im not 100% sure maybe send them a email and ask they are a good company ive used them a few times.
but just too be clear the eeprom may not be the issue with your set so its up to you if you want too go down this route and try it.

Re: Baird jo47.

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?

Ben

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.

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 ??

[benjamin.d.bird]

Re: Baird jo47.

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)

Re: Baird jo47.

Reece do you have any idea what the settings should be?

[ReeceyBurger123]

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.

Re: Baird jo47.

I've re uploaded them

Re: Baird jo47.

Go into factory setting if I remember the reset option is there.
