Re: Samsung UE46C800 Intermittent Vertical Bands
You were right on the money - small amount of oxidation on the board which cleaned off with iso - vertical bands appear to have gone although I'm now left with a single-pixel vertical red line.
Appear to have a burnt out track feeding the ribbon at D22 so scratching my head for a way to jumper that as there's nothing on the ribbon side to solder to.
As an aside do you know of any resource to find TVs with common panels? New price for mine is around 1200€ which is insane so was thinking...Leave a comment:

MP4 on memory stick played on native player on TV shows banding immediately.
Same File played via Bluray through receiver shows no bands for ~ 20 minutes....Leave a comment:

Re: Samsung UE46C800 Intermittent Vertical Bands
Don't think so. I've played material off the server using the BD straight in - still get bands.
I was interested in the fact it wasn't 50Hz.Leave a comment:

Re: Samsung UE46C800 Intermittent Vertical Bands
Factory reset from service menu done - makes no odds.
Went through every resolution available:
1080p - banding appears although interval appears longer
720p and 576p - banding visible as very feint lines - only really visible against a dark background - and disappears with cuts/scene changes. Does appear as the light/dark pair eventually though.Leave a comment:

Forgive my ignorance but what's a COF and how do I identify which one is responsible?...Leave a comment:

Re: Samsung UE46C800 Intermittent Vertical Bands
OK, Back off, vac'd out. It was pretty clean inside but was stored sealed inside its box.
All boards disconnected and inspected. No visible component damage or dry joints. Signs that mainboard and TCON board have got warm at some point - staining underneath both on the chassis.
All sockets blown out with canned air and plugs/ribbons/grounds cleaned with isopropyl.
Back together and.... banding is back after 5-10 minutes. Goes away switching between sources as before.

Samsung UE46C800 Intermittent Vertical Bands
Hi there,
Our sterling UE46C8000 has recently come out of storage and has started intermittently exhibiting two vertical bands - one light, one dark - side-by-side to the left of the screen.
Sources are through a receiver so only using one input on the TV. Changing inputs makes no difference.
Often they will disappear on a scene change watching live material but with recorded material they'll stay until the input source is changed, or switched to menu/guide. Appears to be more prevalent with recorded material.
No vertical bands on the self test.... -
