TV cannot turn on


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

hi welcome to fixya
i want to clarify first the problem sir so as of now the problem with your tv won't power on then you are using again the old main board is that right ? when you use the new replacement main board the tv is functioning will the only problem is that the HDMI / DVI inputs doesn't work. and now you encountered power supply problem like won't start up or something that cut the supply in which the stand by indicator is turn off so as my idea it has a problem with the old board. but before you come up with the board making sure all the connectors coming from the power supply is properly connected to the main board as will as flexible and lvds cable for the T-con board is properly inserted.just let me know if is that what you are asking for so i can give you additional solution thanks for consulting the fixya.
