Have TV Questions? Ask a TV Technician
Hey sorry it took me so long to respond, but I just git the new part and installed it today. I got the part that you suggested and of course to my luck that did not fix the problem. Same as before. I didnt mention in the question but when you put a signal to an input the screen will try to produce a picture. But it comes out as scrambled. But the local channels and menu and sd card work great. Let me know your thoughts.
Yes I replaced the board. It was the d main board exact number you suggested. And there no change what so ever. It did everything it did before.
Yes same exact symptoms. Nothing has changed. But the input board didn't have the hdmi and coax input on it. Only the components. I got the boards used from cracked screens.
I have tried switching them around back and forth in different combinations and no luck. Okay I will try that bridge board. I was trying to just before I only swapped out the anolag board not the hdmi board which seems to be a different board. But I will try that board first. Can I send u a picture of the screen somehow?
