I managed to brick a Samsung le32b450c4wxxu through my own carelessness and this is a post asked for your mercy!
Currently, the TV makes the power on sound when activated with the remote control, however, the backlight doesn't switch on and there is no display, power off sound is heard when switching off. I have tried every "magic" factory reset method (involving pressing or holding certain buttons etc) that I could find, none of them had any effect.
I have tried following the unbrick method on this page, though my exact model isn't listed I am having to improvise. Having opened up my TV I have located what I believe to be the correct chip, it resembles this one (take from the linked page):
I am unable to read the text on my chip as the text is too tiny (I could probably manage it if anyone considers it to be very important), though it is in location IC3001 matching the picture above. The instruction on the page linked to above indicate simply bypassing the chip with a wire during switching the TV on, then after about 20 seconds removing the bypass wire, it refers to terms VCC and SDA which I am unfamiliar with, but I attempted to replicate the blue line from the above picture. One of the pins in the picture has a small arrow pointing to it, I used a similar arrow on my TV to indicate which pins I should short out.
When I did the above I had someone turn on the TV and it actually booted up, showing a noise pattern with a "weak signal" dialogue as there were no inputs plugged in. Success! Except when I remove the wire, shut down, and turn on the TV it reverts to the bricked state, as if it hasn't saved the settings at all. I repeated the process a few times to be sure, and it is still basically bricked.
And so I could use the advice of people who know more about it than I do, as I see it there are a few options open to me, in reverse order of preference:
- Buy a new TV.
- Buy a new main board for the TV.
- Solder a wire onto the pins to permanently bypass the chip in position IC3001.
- Some other option?
If anyone has any advice for me I would be very grateful, and if I can provide any information for you than please just ask!
