Sharp Lc-42SB55E problem

[domix]

Hello,

I have this tv. One day i turn it on it was like all buttona all presed, tv just jumps thru menu, volume is going down automaticly.

I open it and disconnect side buttons. Then i turn tv on and it was normal, but o dont have commens on tv. If i press button on remote, light on tv for remote blink but nothing happends. If i connect side buttons back, volume goimg sown again and inpust source changed automaticy.

I chec the mein board and buy used one from ebay. The boards have boats the same number 715T3251-3 (WK:827). But this whis i bougt was from 26” inch tv with the same numbers on it.

I replaced the board and turn tv on. Side button an IR remote dont work. Input is on HDMI 2, whic i need because i have conneted only on hdmi, tv is in living room and reciever box is connected with hdmi.

Problem is when image shows. The image is like pattern, i have two image on screen (image and half) one at top and half one at bottom. How can i resite image to fit screen.

Thanks

There would be other numbers that should be matched but most likely different from your original board. You have the wrong Main Bd and so the software would be different for a 26inch TV.

715T3251-3 is the blank circuit board P/N not the stuffed circuit board assembly P/N.
Blank board can be stuffed to make many bard assemblies for many model of TV's.
You need to match the barcode numbers.
