[B]ViewSonic Sued Over Allegedly Defective LCD Monitors[/B]
By Phil Milford - Nov 27, 2012 4:12 PM ET

ViewSonic Corp., a maker of visual- display products, was sued by a consumer who contends the company wrongly sold computer monitors while knowing they contained defective parts and would fail prematurely.

Robert Theis of San Francisco, who said he bought a liquid- crystal display monitor that failed, alleges that ViewSonic was aware of defective capacitors that sometimes overheat and cause the units to break down before they should. The company should reimburse...

Re: Instruments/tools needed for TV repair



What exactly is the trace? Isn't the trace the lines on the board under the green sheet that connect the components?

I have heard several times people say don't overheat the board or you'll damage the trace, but I never understood what the trace actually was.

I use a 30watt iron to desolder with a solder sucker, it works fairly well as long as I tin and clean it right before using it....

Thanks selldoor & budm.

The photo gallery of the 3250 was VERY helpful.

I did not change the C33 capacitor... on closer inspection it does appear bulged but I didn't notice it before.

Also, to give credit where it's do, the blue buldged capacitor is Ost, the rest are CapXon.

I tested the transistors and sure enough the one next to the lead is bad. It's 12N50C3 and both before and after I removed it (so much easier to test when it's off the board) I got no reading even when reversing positive/negative...

Re: Fixed a ViewSonic N3260w



I only changed the caps. I will research how to test the fuses and to check the lead by doing a search tonight. I do own a multimeter but it can't check capacitance.

The new caps do have correct polarity, I marked the board and in addition the cap outline emphasized negative.

Here are the pictures of the old caps, I didn't take pictures of the replaced new caps....

Re: Fixed a ViewSonic N3260w



I only replaced the bad ones, the four main ones (they were the only four capacitors included in one of those Ebay kits to recap the power supply) and an additional one that was clearly bulging. Three of the four main ones were leaking, and all four were bulging. I didn't buy the kit, I just ASSumed that any failure would most likely be related solely to them.

The issue is no power at all, not even for a few seconds.

Do you recommend recapping the entire board?

I don't have a capacitance tester...

Re: Fixed a ViewSonic N3260w

I got this monitor for free, it had five bad caps and all were CapXon.

It was built in 11/2006 and used on the production floor where it was on for 18 hours a day. I bought new caps to replace the old and it still won't power on. Since it's such a crap brand I don't really want to spend $60 for a power supply on a TV that has a questionable life. Plus I see a Sceptre brand TV at Wal-Mart for $180+tax new so again, new versus five plus years old.

I think my options are dump it, or hold on to it for a few months and occasionally...
