Re: westinghouse LD-4255VX right side dark
Yep, you're right Tom. Its the upper right tab. No fixing this one. It didn't come loose, it actually had a tiny tear in it. I pressed on it and the picture came in perfect. Pressed it again and everything went out. Tear got worse I guess. I tore the whole tab off now just to see how it worked. It doesn't look that dificcult. I can't believe they don't make replacement tabs.I know they are supposedly put on with a 6 million dollar machine, but that doesn't mean its the only way it can be done. If its about alignment and pressure, I'm quite sure I could make a jig for it.------------signature starts here------------

Re: westinghouse LD-4255VX right side dark
Gonna be a bunch of parts hitting eBay. I paid $80 for this. I know I can get that and more back. Just really wanted to fix it. I've got 3 or 4 people asking me when I'll have a TV ready. That's the good thing, get them working and they go fast. Thanks for the help Tom.------------signature starts here------------

Re: westinghouse LD-4255VX right side dark
I can only imagine what this would cost, but this place claims to be able to replace TABs with "recovered TABs". I guess that means they take them from other panels. Its i n the UK though.https://www.google.com/url?sa=t&sour...53760139,d.dmg------------signature starts here------------

Hello Everyone,
This is my first post so I will try to be as precise as possible without making this post too long winded. Unfortunately I don't have pictures of the original problem but I included images of the TV internals.
I have a Sharp 70LE660U. The problem started a few months ago with the bottom row looking out of sync and was dark on the left side and then fading to transparent on the right side. Shortly after, a dark cloud appeared in the center of the screen. The dark cloud started small and shaded but the image was visible. It also affected the menu area.... -
I have a HP ENVY all-in-one 27 b208na with the screen dark on one side. I expect it's due to a faulty back light or inverter on that side.
My question is where is the inverter located? In the base or behind the display. How do I dismantle the display to check the backlights? I tried to take off the back cover but it cannot be removed completely so does not give good access to the display. Should I gain access to the display from the front? -
Has anyone out there run into screen dark on right most side on a Samsung un50nu7100f. I had half screen at first replaced the strips and back light is lit really good, actually it's brighter than left side when u lift the panel.I assume the panel is toast?... -
I have here a Magnum IA.100 which belongs to my parents.
The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.
Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....
