Default Re: Hitachi LE55A6R9A - No backlight

i would never recommend that anyone bridge over bad led's, especially on a panel that has obvious led flaws. hang on, you should not do it to any tv no matter what.
you are going to have one string of led's drawing more current than the other and more issues will arise, then you will be opening it up again.

You are probably right, but with all things it is risk/reward. The TV is 3 years old and this way was free vs. spending $75 to replace the LED strip. If I get 6 months or more out of it, I’ll consider it a win.

You should at least then turn down the backlights level to as low as possible. When you bypass the LED/s the PWM controlled will run hotter to compensate for the bypassed LED.

Instead of a wire bridge perhaps 2 (two) 1N4007 diodes in series could be used.
