MAKE ME AN OFFER IF YOU ARE INTERESTED. ANY REASONABLE OFFER WILL BE CONSIDERED.

You cannot order a replacement board of any kind just by the TV model number alone. TVs have many different boards for the exact same model number. You could need the serial number to find the right version for your TV and other information to get the correct board. PLEASE message me with any questions you have before ordering a board. I have a lot of returns because the wrong board was ordered by mistake, and this is avoidable. I will typically respond same day. Returns can be avoided with a quick question, and I am more than willing to help. 

I DO ACCEPT RETUENS WITHIN 30 DAYS - BUYER PAYS RETURN SHIPPING

THANK YOU,

Mr. Biggs - TV Man
