Ok, my main board model is 1-893-880-21.
I the same boards on Internet but for different tv models. Do you think they will be suitable:
Board 1 - 65W855C
Board 2 - 65W857C
Board 3 - 55W800C

Check if the power supply has the required voltage and is steady if you haven't already.

Re: SONY KDL 43w805c does not accept commands

OK guys, i have some progression. I bought another main borad from 43w809c. When i switched the set on for the first time with all connected i saw again that self diagnostic screen with colours changing. Reset the TV - was the same. Then i switched off the TV, dosconnected the LVDS cable, switched it back on and connected that cable after few seconds when i could hear the sound from welcome screen and the picture came on. Now it is working but has some strange behaviour at moments - like does not hold the settings after retsrat and others. I can see the TV in my network as 43w809c, do you think it is good idea to change the model number from the service menu?

no need at all, as both are same Specifications. just check firmware if its the last one.. if need update it. if this solved the issue good if not send the boards back to seller.
