Re: 17mb95sNo Standby After Minor Mistake WTF ?

I can't remember how he did it, but there are 2 ways of doing this. First one is to flash firmware through the USB, second you can flash the SPI directly with a programmer.

Re: Samsung UA50F5500 No Power to Some LEDs

oops, I've read your first post again. You stated that you did the testing with the LED's disconnected? That is wrong. Connect the LED's and measure the voltage on each string.

Re: Sony KDL-55EX620 stand-by present, no stand-by light, AC_OFF_DET @.47V

as long as you don't back feed to the PSU, why not? The main board is already damaged to start with.

Re: Repairing digital scales (readout not stablizing)

well, the cell's output is in double digits mV scale on the DMM. Now it depends on how sensitive and the count rating of your DMM. So I am guessing the battery in there is a 6V SLA. I'd wash the...

Re: Repairing digital scales (readout not stablizing)

That is a valid point, since voltage regulators can fail in a weird way and the fact there has been some sort of a power problem on the board too.

Re: Repairing digital scales (readout not stablizing)

actually there are 2 resistors cooked.

Re: LG 55EG9600-UA No Picture or Sound

You may not have turned all of the PSU on. There is a third, something like 1zvt-on for some reason. The LED's won't work until the 24V rail is on. You may also need the Dim control.

Re: Sanyo FW55D25F stuck in color test mode

Re: K9GAG08U0E SAMSUNG nand flash file

that is what I would do. I'd order a new blank nand IC and in the meanwhile I'd look and ask for a nand dump for that TV. If by the time the new IC comes, no dump was found, I'd try copying the saved...
