Picture fault on le40m86

**Rickig** · 04-29-2016, 11:04 AM

Hi guys.
I'm probably answering my own question here but I have the above mentioned set that had the clicking fault. I replaced the bad caps and the tv powered up. I noticed however the freeview wasn't working so I removed the main AV and replaced the eeprom.
Fired tv back up and now the picture is all funny, pink and purple etc. So I immediately thought tcon gone down t400hw01 as it suffers a similar fault.
Replaced tcon. Fault still there, tried new main AV, fault still there, tried a different psu and fault still there.
Just seems odd that it was fine until I changed the eeprom. I even tried another eeprom and fault still there.

Any ideas? Or shall I concede and say it's the panel?

Thanks in advance

' I replaced the bad caps and the tv powered up. I noticed however the freeview wasn't working so I removed the main AV and replaced the eeprom. ' So before replacing the EEPROM, do you get good pictures using other Video sources?

**Rickig** · 04-29-2016, 11:33 AM

Yes picture was fine. That's why I'm scratching my head.

Here's a pic

May be you have to get into the service menu setup screen (MUTE, 1. 8, 2, POWER) and check the panel setup, LVDS signal format, etc. May be the EEPROM was not made for that TV chassis.
It has wrong GAMMA Voltages right now.

Pm me your number talk me through it. But I've tried 2 other good main boards

Hello Rickig,
Can you post a picture for us to see how it is now.
Thanks

You beat me to it. Sorry.

**Rickig** · 04-29-2016, 11:43 AM

Tv clicks to come on as soon as you hit 1. I normally do info menu mute power. Is that same?

**dick_barton** · 04-29-2016, 11:44 AM

The picture looks similar to what happened to me recently when I changed a mainboard. I had to replace the SPI chip from the old board onto the new board then everything was back to normal.

**budm** · 04-29-2016, 11:45 AM

The Mute, 1, 8, 2, power may not work with your model I am not sure.
I do not expect the TV to come on when you hit '1'.
It should come on only after you enter the last button which is the power button.
BTW, the panel cannot cause that off color like that.

**Rickig** · 04-29-2016, 11:46 AM

It's the original board fitted, tried 2 others. Tried a tcon tried a power board.

Option codes

**budm** · 04-29-2016, 11:27 PM

Thanks!
No LVDS codes for these series?

In a lot of cases the Eprom has to be programmed for the board and that could be your issue.Some places sell the Eproms already programmed for the set you need it for.

**dick_barton** · 04-30-2016, 05:54 AM

Have you still got your original main board and the original EEprom you could solder back in place?

**tom66** · 04-30-2016, 06:18 AM

To get into the service menu press, from standby mode, Info Menu Mute Power
Only for European/Australian Samsung sets. US sets use Mute 1 8 2 Power.
