HG55EB690QB Bootloop issue ...

Post by jpk »

Hi All

After having changed my TV options/settings through the service menu, it does not work properly anymore (bootloop mode). This TV set is part of a “hotel/hospitality” series. I’ve used this menu many times but this time I obviously did something wrong …. And I cannot enter the standard menu nor the service menu to perform a factory reset .... (remote control and small joystick in the back of TV set are not taken into account anymore during the bootloop)

Is there a way (simple way ...) to reset the eeprom ? or to boot on a USB stick with a fresh firmware please ? Or any other possible solution to have it back again ?

Many thanks in advance

Open back cover, check mainboard and identify eeprom. Do reset stright on board. Easy, if you know what chip it is.

Could you please show whole mainboard, not only that piece with probably correct chip?

Your first photo is awful, i can not read anything there. Could you re-take it with same or better quality? Need to read labels on it...
Board you refering has poor quality pictures, not useful.

You should take a better close up of the top left, there are EEPROM_stuff labels/pins.
Then read from there
