Hello please tell us what the model number is?
In a dark room if you turn on the TV do you see the panel "Prime" ie show any lighting up please?
Thank you. Your problem is either with the X or Y sustain boards however I would change out the Y sustain board first.Please get the Y sustain board number from your board in the TV and go to www.shopjimmy.com to order a replacement.Let me know how you go.
Hello where did you order the board from please?If the board is ok then you will need to replace the X-sustain board
There is also the logic board that takes the signal from the main board and passes it to the sustain boards
It's normally a good idea to swap out both sustain boards. There are the two upper & lower buffer boards fed from the y-sustain but those symptoms are normally horizontal lines.If you feel the heat sinks of the sustain boards are they warm to the touch and not cold or very hot please?
