Main Board BN97-05375B EEPROM Reset Holes?

Hi,

A friend has a Samsung LED TV model UN32EH4003FXZA that has an Over the Air Station Search Loop (keeps repeating Chan 14 and can Not get out using Mute>1>8>2>Power On).

After much searching we found "UnBricking TV by EEPROM Reset" https://wiki.samygo.tv/index.php5/Un...y_EEPROM_Reset

The Samsung TV Main Board Sticker is BN97-05375B 0078
L6 C 08/08/2012 20:56

We are trying to determine where the EEPROM Reset is on this Main Board?

While "UnBricking TV by EEPROM Reset" does have photos for many different Samsung TVs we could Not find any similar to the BN97-05375B 0078 board.

Searched forum and found viewtopic.php?f=52&t=7237&p=54882&hilit ... 003#p54882 but mainboard is bn41-01897a.

We also searched using "BN97-05375B 0078" and found "Samsung BN94-06008X (BN97-05375B, BN41-01876B) Main Board"
http://www.shopjimmy.com/samsung-bn9...eh4003vxza.htm

Should mention we have done a number of searches to try to find the Samsung LED TV model UN32EH4003FXZA Service Manual but have found Nothing to date.

Appreciate any Help!!!

Thanks

Ken

Only problem could Not find the M_E_Reset jumper hole that he used (video ~ 1:40 to 2:25 minutes) on the BN97-05375B 0078 main board.

only high resoluion photos may help here. 8-leg chips are very important (labels and localisation)

Hi juusso,

"only high resoluion photos may help here. 8-leg chips are very inportant (labels and localisation)" Agree

Am wondering if jumper holes inside the rectangle CN901_DEBUG is the EEPROM Reset for the BN97-05375B 0078 main board?

Do you know? If not where can I find this out?

Thanks

Ken

Hi juusso,

"1. You take photos and show us. 2. we inspect and tell you. this is how it works here." OK

Was able to use a better camera. If problem will redo.
