Samsung LN22A450 LVDS Connector

[mike_s]

I looking for a solution to fix my Samsung LCD (LN22A450) that has a bad/loose LVDS connection on the mainboard. If I put outward (away from the mainboard) pressure on the cable the display work otherwise I just get a white screen. Is there someway to fix this. Thanks in advance.

Measure the pin pitch, i.e. 0.5mm between each pin.

I would try making some thin shims from margerine tub - insert the cable and insert shim/shims to press cable on to the pins then when it is known to work tape it all down.

Or is it the black retaining clip that is broken?

No I don't think the retaining clip is broken. It just doesn't seem to make proper contact and lock in place. Originally there was tape holding down the cable and retainer.

Just pin spacing or also between pins and base of connector?

Thanks

Pin spacing (=pitch) should be enough to narrow down replacement…

I have used strips of scotch tape an the back of the LVDS to increase pressure. Have you already cleaned the connections of the LVDS cable?

Pins spacing is 0.725mm

Re: Samsung LN22A450 LVDS Connector

That's not a very common size. How did you determine it? Tried measuring length and dividing by number of pins?

Did you apply the tape to the cable or connector side?

No I haven't cleaned the connections yet. I will ensure that I do before re-assembly.

Ii used a feeler gauge between the pins. The total length of the pins is 29mm/30 pins = .97

Re: Samsung LN22A450 LVDS Connector

So it's 1mm pitch, good.

Select # of positions then look for identical device.

The Cable, on the plastic tab that inserts into the connector. The idea is to make it a little thicker.
