My WD-82737 is hanging on the blue welcome screen. I did the firmware update and it worked for 2 weeks. I did firmware update a couple more times and got it to boot but the color was blotchy then it went back to hanging on startup screen. I have heard this indicates a bad power board and or main board. I found this chassis kit on shop jimmy (Out of Stock) https://www.shopjimmy.com/mitsubishi...is.htm?alert=1

I could probably install it myself. If I can get the part.

Is there a way to diagnose this better? What would a tech charge for that repair approximately?

Any advice is greatly appreciated.

Thanks for the response

I found a power board on ebay and installed it................ still stuck on welcome screen. So I guess it is the main board. Is there another component which could be the culprit?
