Re: Fixing a Maxent MX26x3 LCD TV

From: "Rocntoy" <rocntoy@xxxxxxx> Date: Wed, 03 Feb 2010 06:50:I've had excellent results from just appling a very small amount of liquid
flux, then reflowing the existing crap solder with a small tip of a soldering iron (no excess solder on the tip, just tinned and nearly wiped
clean/dry). By a very small amount of liquid flux, I mean a small amount on the end of a wood toothpick, then dragged over a row of pins. Working wih a magnifier lamp (or a magnifier lens with good lighting), it's easy to see when a thin line of flux is visible along a row of pins. With a magnifier and good vision, it should be clearly visible when the solder reflows, as each pin is individually touched with the iron tip. If the heatsink is exending out over the pins, it won't be as easy, but probably not too difficult to accomplish with some patience and persistence.

Cheers, WB.

<behindontaxes@xxxxxxxxxx> wrote in message news:Xns9D0C8BB6B418behindontaxesxemapsc@xxxxxxxxxxxx I have a nonworking Maxent MX26X3 LCD TV/monitor. Immediately upon powerup, it will generate anomalous vertical multicolored lines throughout the entire screen with a blue background. I've read about two known solutions, and I think both are related to one root cause. On FixYa, people have reported favorably changing the behavior of the TV by twisting a green heatsink that sits on top of a 208pin QFP. That QFP is made by Trident, so I suspect it handles the video. One person used heat to reflow the pins. There's a thread on badcaps.net featuring the MX26x3 TV but nobody has posted successful repair by replacing the capacitors. I'd like to try something similar to reflowing the pins. While I have access to a heat gun, I can't accurately gauge temperature. I also don't have a temperature marker. I think I would ruin the work with thermal shock from cooling down. I was considering adding more solder to all 208pins by flooding the pins with solder and using solder braid to remove excess solder and bridges, etc. I'd love to get your thoughts on how to go forward with trying to repair this TV. Thanks for reading.
I am having the same problem. I took the tv to a repair shop and they told me that the logic board was bad and needed to be replaced. Does this make sense to any of you? Or is there another fix? Thanks for the info.
