Samsung 55" LED TV
Model- UN55D6003SFXZA
T-con Board #- T546HW02
Main Board #- BN94-05429D

When I plug tv in, the Samsung SmartTV startup screen comes on for a few seconds then screen goes blank. The red indicator light at bottom right flashes a total of 5 times after plugging in. Pushing power button on tv or on remote leads to 1 blink from indicator light.

I received this TV from a friend. He thought the power supply was faulty. I tested the backlight by unplugging the main board from the power supply-- Backlight appears to be working. I replaced T-con board since part was reasonably cheap. Same symptoms as before replacement. My next step was to replace the main board but cannot find any online. Now I plan to have the main board repaired, but would like to make sure that is the issue before spending 125 dollars on this item.

I am not very skilled with electronics outside of plug and play type situations. The main board does not appear to have any burnt spots or anything like that....best I can tell. I can post pics of anything needed, just need to know what will help.

Thank you all for your time,
