| There is +5V at the microprocessor. The actual B+ at standby mode is 106V and goes down to +95V when power is on...Thanks |

| There may be no 5V to the microprocessor. Check R3509 and D6501. Replace R3509 with a 47k 1 Watt version (4822 053 10473). D6501 is type BZX79B5V6 (4822 130 34173). Check the +150 volt rail, 145V is too low |

| When power is turned on the main power switch,red LED lights then and disappear signaling power is ok but then goes to standby mode lighting the red LED again. I replaced the vertical out IC tda9302h and it worked but not for long. The same problem occured again,shutting high voltage and going to standby mode again. I replaced the vertical out again but did not cure the problem....Any ideas causing the tv to go to protect mode?Thanks for your time.God bless us all !!! |
