Hello there and welcome to Just Answer. My name is ***** ***** I will be assisting you today. I am an engineer with over 30 years of electrical and electronic training, repair and installation experience. I will try and answer your question accurately and precisely so that we can get you on your way.
I need to gather some more information from you in order to help.
If you cycle through the inputs while the set is tiling, is it present on each input?
Possibly, I need to find a schematic for it but I would suggest that the 'Main' board is bad. Some sets also have a logic board so I need to determine that since that could cause similar symptoms.I'm here most days. It may take me a while to answer if I am away from my laptop.
Probably not the best if it is based on a Fujitsu. I'm trying to get a manual for it now.What you can do when you get out to the site is pull the back off and photograph it for me. Then get the number of the Main board and any logic board that is present.
Yes. It appears that some components may have been made by Runco which is a high end projector brand. I'm not finding a service manual on it. When I get into work tomorrow I'll jump onto my network and see if we have one. I somehow doubt it. Never seen one in the shop.
As I thought, I have nothing on this set. Please post a photo of the back of the TV when you can. Thanks.
