Re: Samsung LE23R86WD with vertical rainbow stripes

Fired it up again today. Confirmed that it does behave slightly better when cold. I'm able to get the image and menus (occasionally with some horizontal static lines) for about 3 minutes before its back to vertical rainbows.

Re: Samsung LE23R86WD with vertical rainbow stripes

It appears that I may be the one to blame for it because that symptom only started only some time after I put it back together after taking it apart (but it didn't start right away, it did function for a while )

If I disconnect the LVDS it's still looping, though its only evident through the changing backlight.

Urgh, I need better multimeter probes. But here are the measurements:

[code]nc 0 | nc 0
12v 11.9 | 12v 11.9
12v 11.9 | gnd 0
gnd 0 | gnd 0
5.2v 5.35 | 5.3v 5.35
5.2v 5.35 | 5.3v 5.35

The voltages start to fall when the TV shuts itself off for a second before it turns back on.

I've also got a 100Mhz oscilloscope if thats...

Hey guys. I found this TV in the dumpster with nothing other than a scratch on the base! If nothing else it had no business being in the bin marked for 'plastic'! It pays to recycle

Anyway, I brought it home it powered up fine but 98% of the time it only shows vertical rainbow stripes across the entire screen. Its like there some kind of jumpy connection or something because every so often if you're lucky you do get a flicker of the proper image (and the menus and such do work). It also seems to be stuck in a loop of shutting down and turning back on, with the screen going black,...

Hello. Simon here. I found a nice Samsung LCD in the dumpster (somebody tried to 'recycle' it as 'plastic') and I'm hoping I can get it back into shape
