Samsung Accidental MICOM Upgrade LA32D550K1RMXL

[kewyn]

Hi everyone

I have a Samsung LCD TV (LA32D550K1RMXL),It has developed a permanent White line in the TOP, I tried everything (Factory reset, changing cables, firmware upgrade ...) but with no luck I knew about service menu, I tried changing some settings, till I accidentally hit MICOM Upgrade,
it took so long with no response at all, I powered off the TV, powered on again & it's dead blank screen. the remote & front panel no longer works, there is a Red light at the back coming from the Digital Audio out.
what can I do to make it work again ?

I called samsung service expert came and told me to change the main board.


I've attached my TV main board original pics with this query. Kindly help to solve my problem.

Well the MICOM is the main system controller IC (power, standby, IR etc) if you have overwritten the firmware of that chip somehow you may not be easily able to fix that without a new main board.

However it's worth noting that if it did have a white line across the display (LCD) panel then the display panel was probably defective anyway, and that can't be fixed without a new LCD.

At least the advice from Samsung is consistent. Similar story from someone else last week or so. No idea how they went.
