Re: Dell 3008wfp faulty power supply

I got a new Tcon board for my display but it didn't make a difference. It seems that it's the bonding that's broken. At first I could make the problem disappear by applying pressure at it but now it doesn't seem to have effect anymore. Buying a new panel is not cost effective so I'll probably break the display apart and put the parts on eBay.

Re: Dell 3008wfp faulty power supply

So I got the new tcon board from Buyqual. Although it was 6870C-0183E instead of 6870C-0183D and is not entirely compatible with the display I managed to revive the lower part of the dispay by pressing on the lowest ribbon. It seems that the tcon board is faulty and I just need to find a correct replacement.

I attached a couple of pics of the current situation. The first image represents the situation before I applied pressure on the ribbon. The second pic shows the horizontal displacement of the image caused by the incompatible...

Re: Dell 3008wfp faulty power supply

Thanks for the info. I tried cold spraying all the ribbons connecting to the screen but there was no effect in the image. I also sprayed the connections coming from tcon board without results.

Maybe I'll try replacing the tcon board then. I couldn't find it in Aliexpress but it seems to be available at [URL="http://www.buyqual.com/6870c-0183d-lg-logic-board-lm300wq5-sta1.html"]Buyqual[/URL].Re: Dell 3008wfp faulty power supply

Re: Dell 3008wfp faulty power supply

I did remove the metal cover in front of the panel and exposed the ribbons that connect to the screen (the picture shows the four ribbons on the left side). They seemed intact and I couldn't generate any effect in the image by pressing the ribbons. I couldn't figure a way to disassemble the display unit any further. Well, at least not in a way that allows me to put it back together....

Re: Dell 3008wfp faulty power supply

Thank you for the tip tom66. I took the display apart and tried applying pressure to and gently moving around all the bonding (4 on the left side, 12 on the top) in the display. Unfortunately I didn't see any response in the image. I also tried pushing the cable connections on the Tcon board without response.

I figured that the Tcon board might have bad internal connections so I gave it 10 minutes of oven treatment at 195 degrees. This attempt was futile as well.

At the moment I am inclined to think that it is the...

Re: Dell 3008wfp faulty power supply

I have a Dell 3008 WFP that does power on normally but the image is partially messed up as shown in the attached picture. I suppose this is not power supply related but if someone has any ideas what to fix I'd appreciate it very much.

I haven't opened up the display yet so I don't know if there's any visible indications of broken components. I have waited for the display to heat up but that doesn't make any difference. The colour of the lower part of the display responds to input signal but with a delay of several seconds. The...
