Re: Sharp Aquos LC-37G4U LCD Distortion

I checked the contiuity of the all flex cables between main board to T-Conn to Panel. Since I have a schematic I will try to probe the lines. It may give me a clue as to where the defect is located.

Re: Sharp Aquos LC-37G4U LCD Distortion

It is not a function of the input. The display anamoly is present with all inputs (I.e., TV tuner and DVD inputs). The OSD also appears to have the distortion as well. Only the left half of the screen is affected.

Re: Sharp Aquos LC-37G4U LCD Distortion

I replaced the T-Conn board and got exactly the same problem. Does not appear to be a T-Conn problem. Is it possible to investigate this a little further to isolate to LCD screen??

I now have the service manual with schematics for the TV monitor.

Thanks Wizard!

You are a Pro and will do what you suggest. I have been reading your other posts and your recommendations have been very good.

BTW. I am a Newbie to LCD/Plasma repair but have extensive background in repairing electronics of all other types over the years.

I have a 37" sharp LCD with a image problem. The right half of the picture is fine. The left side has distorted colors (washed out and dark). The images on the left side do not refresh at a normal rate (I.e., when a picture is supposed to diasppear the image slowly fades).

I suspect that the LCD controller (T-Con) board is bad. There are two flex connectors that I suspect controls each side of the picture. Next task is to clean and reseat the connectors.

I was going to buy and study the Sharp service manual. But I thought someone has any experince with this...
