Need INVFT320A Inverter

Re: Need INVFT320A Inverter

what does the picture on the tv look like after this conversion as the leds will not have diffuser lens fitted over them like on proper strips

The LED strips I mentioned are actually LED backlight replacement strips. Perhaps then I'm not calling it by the correct name. These are Samsung replacements that I get off e-bay and they do come with the diffuser lens attached. I have done this procedure about five (5) times already. 2-32", 1-42", 1-46" and 1-55" with success. The picture shows like normal and I have had no callbacks since.

As labeled on the board:
IN-PW?(M) = Internal PWM dimming
EX-PW?(M) = External PWM Dimming
ON/OFF = BL-ON BACKLIGHTS ON/OFF
These signal are from the main board.
the Dimming control signal will one of the two but not both.

Thank for this information budm.

Yes...and the TV now uses less power.....of course you would have to disable the Inverter section.....may have to cut copper traces or remove links so there is no unnecessary power usage.

OK, it's official, I'm a knob! Of course, replacement inverter didn't change anything because I have faulty tubes. Build one of those CFL testers (a cut down CFL globe) and it fires up off the inverter. Even the old inverter which I put back in.
Do I scrap or what? 32 inch. Not much demand or interest. Think I might put it aside and if I get another defective 32 inch through with broken panel but good tubes I might do a surgery job on it. Can't justify the LED conversion unless I do it as a learning experience.
Sorry to all whose time I wasted trying to fault find a working inverter.
