    Your unit need to take apart and check all cable connectors connected from the power supply to the main board and lcd controller board for loose connection. Also, leaky/dried electrolytic capacitor in the power supply section will do the same symptom. It needs a warm-up to make itself stable but it will get worst. Sometimes it has a bulged /dome at the top but not all, you must have a capacitor checker to determine its condition. If you don't have necessary tools and test instrument and can't do the job yourself, I would advice you to look for a qualified technician to troubleshoot the symptom.



    Also check first if the unit is under warranty/extended warranty, avail it because the manufacturer of your unit will fix it for free or a little charged only. Don't attempt to open the back panel, it will void the warranty.



    Hope I helped you.



    Have a nice day!

Trying to get the color codes for the speakers wires someone cut my radio wires and im trying to install new one.


Usually speaker wires have a solid color, and a stripe of another color on them. Sometimes it's a solid color, and rings going around the wire of another color.

The striped wire is the Positive. Then there will be a wire, that is the same color as the stripe. (On the striped wire) This is the Ground wire.

Problem with green color


One of your convergence IC's has burned out and needs to be replaced. If the green color is sagging from the top or bottom then the IC that handles the Green Vertical (GV) is bad, and if the green has moved inward on the left or right sides then the IC that handles the Green Horizontal (GH) is bad. Toshiba projection TV's typically use the STK392-110, and it is a good idea to go ahead and replace both IC's with the updated STK392-150's. If you do not have experience replacing convergence IC's then have a qualified tech handle it for you.
