Question about Toshiba 61H70 61" Rear Projection Television
Powers up,can see a picture (does not flip) looks like pin cushion,can hear sound,but looks like part of screen does the old style horizontal flipping ,then after being on for a few minutes screen goes black and power light blinks. have done hard reset didnt help,also convergence out of line also.tried to adjust convergence with remote doesnt help.
All the symptoms in your tv point to a convergence problem,the unit has 3 amplifiers one for each color,this amplifier IC's need to be replaced and then realign the colors,sometimes just by replacing the Ic's you are able to realign the color with the remote but sometimes they need to be realign from the service menu. You can identify the IC's because they are mounted in heatsinks and by its marking,in the front they have STK--- ---,6 numbers after the letters,their size is about 2.5 " long and 1.5" wide with a row of pins solder to the main board.If you are familiar with tv service this information will help but if you are not too familiar be safe and call for assistance from a servicer.
