Facing TV Problems? Ask a TV Technician.
Welcome to the site! I'm Dan. Please reply back so I know you're here. Also, are you with the unit now?
OK. I'll need the part numbers off the new boards you installed. Also, where did you get them?
OK pulling up my service data now. Stand by.
OK remove the SD board completely from the TV. Set it aside on a separate table. Now try to turn the TV on. Tell me if you're still seeing 7 blinks.
Reinstall the SD and do the same test for the SU.
OK, multimeter handy?
OK make a list of the following voltages. Some might be there and some might not... just check all of them and report back. >>LIST IS HERE<<
Just reply back to this thread. No rush.
Looks like your question fell off the list. Not sure why. Let me know if you still need help with the Panasonic...
OK, no problem. I'll be around.
