Re: Samsung 305T - Video Distortions

Hey guys,

Sorry I've not updated in a long time. Just noticed that there was posts again.

I ended up reflowing the ALTERA BGA chip myself. First time I tried the heat gun method talked about here: [url]http://hardforum.com/showthread.php?t=1527751[/url] that lasted a few weeks.

I reflowed it a second time doing the same thing. This time I heated it longer. It held up about a month after that one.

Finally I started reading about how the guys with the HP DV9000/DV6000 laptops were oven...

Re: Samsung 305T - Video Distortions

I was reading about actual reballing last night. That seems like the way to go. There is a reballing service listed on eBay classified. They want $75 to reball and warranty their work for 1 year.

For the moment, I have it running normally. It's been going for about 12 hours now with no issues. I read about the Apple laptop guys putting some card board under their boards to put more pressure on their chips and make contact. So that's what I did. I did put my 3 - 120mm exhaust fan hood back on. It's pushing out allot of warm air....

Re: Samsung 305T - Video Distortions



I also found that thread when this problem first started. What I did was made a Plexiglas fan shroud that fits over the vent holes on the top rear of the monitor. On that I mounted 3 - 120mm computer fans. They are each wired to a USB plug that goes in to the USB ports on the monitor. At only 5V the fans are very quite, yet due to their size they move allot of air out of the monitor.

The damage has already been done, but going forward hopefully my fans will help keep it from happening again after getting it fi...

Well for an update. I've not been totally convinced caps are at the root of my issues.

I spent all day searching for more information when I finally found out the logic board is the same as gateways 30" monitors ( LTM300M1C8LV3.2 ) then I found these forum threads that seem to have the same problems with their gateways as I'm having. Though mine is not near as bad yet.

Re: Samsung 305T - Video Distortions



Please do tell or point me in the correct direction. I'm very worried about this as it is a very high dollar monitor. Only reason I was able to get it was I amazingly found it for 1/4 of the retail price. I couldn't pass that up. No way I could ever justify spending full retail even on this monitor, even though it's the greatest monitor I've ever used!

I made a list of all the caps on the 3 boards:

Logic Board

5 - V0033 100 25T
2 - 671D 10 50V
1 - V1444 100 16J

Re: Samsung 305T - Video Distortions

Ok, here are the pics. I tried to get as clear and close as I could.

Nothing really stands out as far as caps go, with the exception of where I put a red arrow point to one. It seems to have a very slight dome to it, where as the others all seem very flat topped.

Hopefully someone will be able to notice something I don't or have some ideas or suggestions.

Also what about the ebay guy? He seems to think he's got it figured out. Any ideas on what he is adding a fan to or cooling extra? Or what he's...

Re: Samsung 305T - Video Distortions



Wow thanks, that will be a great help.

I must say I'm really worried about opening this thing up. I've repaired the caps on a free HP lcd that was given to me, but this is quite a different beast, one with allot of $$ involved....

Hey Everyone,

My Monitor started acting very strange a few days ago, and I've been searching for info on a possible fix. I ran across these forums and have been very impressed with the amount of information available here. Unfortunately I've not found the same problem that I'm having, so I figured I'd post and see if anyone can point me in the correct direction.

My monitor is a Samsung 305T. A few days ago it started having a light almost transparent green-ish or red-ish pixelated (is that a word?) color appearing over the screen. I can see everything but it's making...
