24-12-2008 | | As soon as the ac power is connected the tv clicks and the standby measures ~2V (jumos from 1.8 to 2.4V). I think the standby voltage is being turned on / off :-( |
24-12-2008 | | Part of what i'm trying to figure out is if the voltage is bad which is causing everything else to fail or if something else is failing which is causing the standby voltage to cut off through a protection circuit. Not sure what teh best way to check this |

24-12-2008 | Re: bad voltage | If the standby source can be isolated from the rest of the set, this will let you know if the "voltage is bad."
I suspect a heavier than normal load (shorted component?) being reflected back each time set tries to "start." |

There is nothing wrong wit |
24-12-2008 | | The "bad voltage" could easily be loaded down because of some type of short(just like it was mentioned)
As an example, lets say there is something wrong with the inverter which will instantly put a massive load on the supply & shut down. |

25-12-2008 | | K, christmas day and I had a few hours to play around again. So measuring standby current by disconnecting one of the pins and using the digital MM, approx 50ma (seems low to me).
I have disconnected the power to the inverters and the dimming controls |
25-12-2008 | | Threw 4.5 volts into the standby line and the relay stays on this time! :-)
The led is indicating 7 blinks which translate to "7 times Internal temperature rise (mainly on the panel side)". dont know if this is a lie or not.... but quite exciti |
