Be sure to install the screws in the T-CON board before applying power. Damage to the board will occur. PANEL Test: To run the T-CON “Panel Test”, use the Smart Test Jig or remove the LVDS cables. Jump 12V to the 12V fuses. Apply 3.3V to pin-44 on CN1. White, Red, Blue, Green and Black patterns show on screen.

This is CA-266S 32-65inch LED TV backlight board Led universal inverter 80-480mA Constant current board. Output voltage: automatic adaptation below 88V (minimum limit for input voltage, no depressurization), Output current: the default 80mA. Increases the current by shorting the R22 R21 R18 R15 R24 resistor. Each resistor 80mA. Highest 480mA.

Looks to me like the LCD panel needs each of those four supply rails, plus Vcom, plus Vddt (assuming you're using the touch function), plus another supply for the backlight. The backlight will be a bit more than 12V (4 white/blue LEDs in series at a bit over 3V each) at about 480mA total at full brightness.

Some more LCD TV board numbers and service menu Codes or factory setting mode opening code. Universal LED TV Boards Factory Setting Code or Service Menu Code. Board Number Code. TBI.T07-MABE HG - Menu or Contrast,1950 or 9735. TP.MS1306.PB772 - Menu or Contrast,1950 or 9735. T.VST59.031.A81A8 - Menu, then 1147.

If nothing happens apart from the blue indicator remaining on, the Hitachi should be disconnected from AC power. The power button on the TV should be pressed and held for 20 seconds. After a minute, the TV should be plugged back in and the power button pressed once. If the problem persists, it indicates an internal failure that requires service.
Sony TV Service Menu Codes & Instructions. Method 1. Press the following buttons on the remote control once the TV is in standby mode: Displaying “5” {POWER} Method 2. Press the following buttons on the remote control once the TV is in standby mode: Displaying “5” A “VOL+” “POWER”. Method 3.
Voltage value of AVDD Voltage. We will get 10v to 20v DC voltage in most of the LCD LED TV panels. This means the minimum value of AVDD voltage is 10v and the maximum value of AVDD voltage is 20v. So if you get AVDD voltage less then 10v and more then 20v this means your circuit is not working properly. And you have to fix the problem as well There are lots of programmers available in the market but RT809f and RT809H are most popular for LCD LED Repairing. I also use these two programmers to repair the LCD LED TV. 4. Backlight Tester. There are have two types of backlight tester one is CCFL LCD backlight tester and another is LED backlight tester.
