this unit will not power on, there is no green light and no click when i press the power button or use the remote power button
could this be due to the convergance chips or could it just be a bad power switch
If there is no click nor LED, you either have a completely dead power supply or the micro is not getting the command to turn on. Front panel control switches could be bad. You can tell by disconnecting the front panel by unplugging the cable going to it. If you pull the front panel there will be an inline connector going to the panel. Unplug the control panel and try starting the set with the remote. If nothing, the power supply is dead and you will need some troubleshooting and repair.
I disconnect the front panel as you said and tried the remote but still nothing.
so i would assume that i need to replace or repair the power supply board
ill have to see if i can find a service manual so i can try the repair myself
If it is completely dead, you likely have a bad regulator or related problem in the SMPS. You can look at the links in the sticky for the DIY repair forum and you may find a place to download the manual.
