Figured someone in these forums has done this or made an attempt. Got a 42" Vizio "piece of crap" that I bought 2 years ago that has developed a green overlay on the screen which won't go away. Vizio wants to offer me refurbished replacement for a reduced price but I'm declining.

Has anyone tried to take these TV's apart and re-seat the connections? Seen this done on youtube but have reservations on the capacitors still holding voltage. Figured I'm ultimately going to get a new Samsung model but until I get my tax refund thought I'd try to get this one going again until then. Any comments welcome!

What, no warranty? I believe here in the EU, even if it only had 1 year warranty by the retailer, a TV could be expected to last more than 2 years so they'd have to fix it. Of course it may not be free, and shipping costs could be more than a new TV.

Flat TV's are not so hazardous as CRT tubes, so I don't believe you find any capacitors holding voltage.

A top tip. Pull the power cable out with the tv on. This will drain a little extra power from the tv. It will not drain every last drop of power, but will help make whatever your working on abit safer. For a flat screen that about all I would do.

Only came with a 1 year warranty, after which the green tinting started of course. TV cost 500.00 usd when I bought it, they offered me a new different but similar model for half that plus taxes shipping included. It comes with the same warranty but I don't really want to take another chance on this brand again.

Thanks for the unplug tip, will try it and see!

The CRT panel itself is safe enough, but watch out if it uses cold cathode back lighting. Those use higher discharge voltages and should be treated with respect.

All hail the Great Capacitor Brand Finder
