Nothing to do, even writing both of them remains the same problem I think it's definitely the processor bad.
Lotas Thanks anyway...

I am attaching the contents of the video eprom.
Unfortunately I can't find cards for 40'' at the moment.
Thank you for your time...Leave a comment:

New, reprogrammed EPROM, same result. LED on, accepts commands from the remote control but black screen and no backlight.
MB is faulty.
Do you know if I can mount other MB on that tv ?
Thanks anyway for everything....Leave a comment:

Nothing to do, always standby LED on and that's it.
I tried several times to delete the eprom, verify it and write your firmware and always checked correctly by the programmer, but I always get the same result.
Thank you for your patience.
I'll see if I can find a used mainboard.Leave a comment:

I'll try again. I've always unsoldered the eprom, both to read it and to write it.Leave a comment:

Excuse me what I just sent is the original one I read the first time, maybe you meant to re-read what I wrote with what you sent me?Leave a comment:

I did the dump by unsoldering the eprom and connecting it with adapter to the programmer, I'll send it back if you have time take a look at it. Thank you...Leave a comment:

Hello Lotas, thank you for your availability, unfortunately I don't find any hardware problems on the mainboard, could I try other firmware that you know of or something else ?Leave a comment:

The dump is original, I tried to disconnect the flat lvds but the problem persists...Leave a comment:

Thanks for the quick reply.
I programmed the IC1604 eprom with the supplied firmware, with the status register byte 0X88 and 0X42.
Now the standby LED is on, If I try to turn it on the LED will turn off and come back on immediately. The main activates the power supply that supplies the 12 volts for 20 seconds and then returns to 8v and repeats this operation continuously.
Strangely I find that at the output of the Q211 I find only 1.35 v while in the 2 outputs of Q209 I regularly find 12v.
No voltage on the L400-UT.
Unfortunately I can't...Leave a comment:
