    Hi Daniel,
    These are big subjects, I suggest that you get a book on tv repair from amazon.com because it has full explanation how both and other circuits work.

      You need to check if there is any pulse going to the base of HOT. No pulse means no high voltage eventhough the B+ voltage is good.

      Hi Alberto,

      Do you mean the power supply suppose to generate 24 volt but now only have 8 Volt? If yes then check for bad e-caps along the output line and make sure the output diode (schottky diodes) is not leaky. Sometimes a shorted component component in the mainboard will pull down the output voltage too.

      I'm assuming you check if all the other output voltages are good in the power supply.

    hi jestine,
                    Is the mainboard of lcd monitor repairable?like The one that  i repaired brand name HANNS.G that i suspect is the mainboard was the problem becausE of the on and off  condition.Is the MCU is involve in this problem or the cyrstal?

      September 19, 2012 at 12:48 am

      Hi jojo,

      If the supply are good to the MCU IC then most probably the MCU could have fault. MCU, Eeprom and flash rom ic if you have the original data then you can overwrite the old data with a programmer. The problem is sometimes it is hard to find the original programs for those ICs.

      Hi Rafaqat,

      Standby mode means either the cpu, optoisolator circuit or even the main power supply itself have problem. First make sure the cpu is getting the right voltage, and you may need to check for bad components in the optoisolator ic area. Check also to see if there is any supply voltage to the power ic in the main power supply.
