UE32D5500 Bricked

[Rogerthat]

Hello,
Im new here, but I've been reading this forum since a month or so.

I was in the service menu trying to enable the PVR but instead I've just messed up my UE32D5500. Now I can't unbricked it.
Could someone please help me to identify the Eeprom in my main board, and telling me which pins I should join to unbrick it?

Here I attached a few pictures of the main board, the first is just to see the full main board, but in the next you can see the ICs I suspect can be too:

I must say that I already try to unbrick it with the ATMLH110 (second link), but after a few tries, nothing happend, so I decided to came here and ask.

Any help will be more than welcome.

Thanks a lot in advance,
Roger.

1) IC901 (2nd picture): main SoC EEPROM
2) IC1203 (last picture): submicom (Weltrend chip) EEPROM
3) HDMI EDID EEPROMs (picture 4 & 5)
4) IC410 (3rd picture): no idea - unless it's close to VGA input (if any), in that case, it's most probably VGA EDID EEPROM

Personally (just a guess - no guaranties / no responsibility) I'd try 1) IC901 first - if I understand correctly, you already tried to short that one, but perhaps you did something not quite right? Try again - make sure you are shorting the right pins, and in the right moment!

2) IC1203 may be worth a try, too.

EU*D5500 is Mstar 5 based (T-MST5* firmware) - I can't find any EEPROM reset procedure already documented / EEPROM reset success report anywhere for this particular model, so you are in uncharted waters. There is always a possibility EEPROM reinit/reset functions are simply not implemented in T-MST5* firmware branches; in that case, you may need to manually reprogram IC901 or IC1203 (or both) with values extracted from another, working TV (exactly the same model & version) to unbrick your TV.

Also, it's not awfully clear what excatly you messed in factory menu - there are some options in there (e.g, triggering micom upgrade) which are utterly destructive from any practical perspective. In such case, your only (reasonable) option may be mainboard replacement.

Hi Roger,
Did you get to unbrick your 5500 TV?

Thanks,

Roger,

same question, did you succeed?
