Using the philco ph42m led a4 board on the semp toshiba le4053(a) First, if the image is bad, when they put the philco plate on the semp, go to the semp tec information 012/12 and tsound you have it, depending on the display manufacturer, you type 062598 menu code, depending on the display you type the corresponding code After that's done, the TV will turn on with a normal image, just write philco and accept it using the remote philco just... to turn it back on, download the semp update and update it with the pen drive... done that, the tv is ready always again.

The Toshiba logo appears and then the image disappears Main board goes into backlight protection. If the adaptation of placing a 10k or 15k resistor in place of the r766 does not work, you can perform another procedure to remove the backlight protection. Place a 10k resistor from pin 41 of the ci oz9916 (ci backlight) to ground. Dennys Gross
