02-09-2010 | Dead Technosonic LCD 1908 | Many thanks I had the same fault , I used the link to obtain the diodes which cost £10.75 delivered next day and with the aid of a steady hand and a soldering iron tv works again :D |

02-09-2010 | | C507 has 155 volts across it, i will recheck this cap to make sure its ok , after checking around the board and then creating this post i started to think it was beyond a cap or resistor or diode , perhaps that transistor on the heat sink Q502 , i will re |
02-09-2010 | | It tests good but to be sure i replaced it with a 470uf at 250 volts and still nothing

03-09-2010 | | It's OK checking the rectified mains voltage... but what about the start up voltage for the switch-mode controller.
Before anything happens there needs to be the rectified mains AND the supply voltage for the power controller chip.
Your best bet is |
03-09-2010 | | 155 volts is your Raw B-Plus, or rectified mains, as Pentode pointed out.
I've been trying to have kramden66 proceed in a logical manner, but it appeared he didn't want to cooperate.
So, to continue....
Next we will see if you have ANY secondary vo |

03-09-2010 | | S/C line ? if i checked the transistor on the heat sink and its bad then its probably whats wrong but time has slowed me down on this so i can only do a little here and there

Sorry for multiple post. 7:40 post has rare "edit" button, but not this one. |

What are the differences in schematic diagram was betwen LE37B650 LE37C650? |
03-09-2010 | | jts1957 i haven't been ignoring you i've just been mentioning ideas of what might be wrong , when i can i will check the voltages on the capacitors you mentioned, time has not allowed me to do much with the set , so probably Saturday i will be able to rea |
