Re: Samsung LN46A550P3F no power/clicking problem

Replaced main board which solved the problem.
Thanks for the help.

Re: Samsung LN46A550P3F no power/clicking problem

Some clarification and an update on the problem with the tv. When the tv is connected to power the relay immediately energizes and the power light illuminates. The relay cycles every 25 seconds as long as power is applied. Pressing the remote power button causes the tv power light to flicker but has no other effect. Power supply voltages are correct and stable.

Re: Samsung LN46A550P3F no power/clicking problem

Thanks for the responses. I have attached a list containing everything that is printed on the 8 pin chips that are mounted on the main board. I don't see any that seems to indicate which is the eeprom.
The 5VSTBY is stable....

I have a model LN46A550P3F with the won't power on/clicking problem. The power supply/backlight inverter board has been replaced and was no help. I think I have identified the eeproms as IC1000 AND IC1003 (ATMLH820 02B1) which are marked in the attached images. The main board is a BN97-02643A and also shows BOT BN41-00975B. I would like to try the eeprom reset but am not sure which is the correct eeprom and also to make sure these are the correct eeproms. I would very much appreciate any help....

Re: Samsung LN46A550P3F - No Power - Clicking

I have a model LN46A550P3F with the same problem - no power/clicking. The power supply/backlight inverter board has been replaced and was no help. I think I have identified the eeproms as IC1000 AND IC1003 (ATMLH820 02B1) which are marked in the attached images. I think one may be the backup. The main board is a BN97-02643A and also shows BOT BN41-00975B. I would like to try the eeprom reset but am not sure which would be the correct eeprom and if these are the correct eeproms. I would very much appreciate any help....
