The set had a bad vertical output IC and when the IC heated up it took out something in the power supply. Most likly in the sweep supply, that supplys the voltage to the vertical IC. If your not a tech, Please call one, as A TV set is not a place to experiment with. A good tech may even be able to repair the module as Zenths are made to replace the entire board when theres a service problem.. Go to http://ptscorp.com, click on technical assitance then finding the board you need by putting in the model # and this will come up with the board price to give you an idea on the replacement cost for parts and see if you want to invest that as well as the labor cost. Good Luck

Screen is black


sounds like it was enough to pop something in the tv, smell the back of the tv smell if anything smells burnt or hot. unplug the tv and let stand for about a hour unplugged then trying it again but if it does smell chances are you will have to see if your still under warrenty and have the unit replaced.

Washer squealed, gave off black smoke in spin cycle


For sure change the belt. Clean the pulleys with a solvent to remove anything oily or like melted belt. The machine probably was overloaded. If it's a front loader, check the bearings.

My LG LCD flat screen tv shut off one night and smelt like burnt rubber. It turned back on fine but I'm worried it will catch fire


You are safe. :) It may have shut off from a voltage spike or brown-out on the line. There are several fuses inside of the TV that are supposed to blow before anything catches fire. If it starts smelling again, then unplug it and take it to a service center.

Green screen, no picture. tv shuts off by it self after 30 sec


This is a simple fix and not hard to do, first you must get the speaker grill off, usaly two screws on the bottom and they might be hidden under to caps, then remove the acsess cover from the front. From there you should see a control box with six controls, three on top of three,,,,One part label "screen" the other "focus" now turn the set on and tune to a input that HAS NO SIGNAL this should give you a black pix, probley not now but it's supose to be black. Now turn the ones marked screen , one at a time counter clockwise just a little to get the pix compleatly black, now starting with one color turn the control slowly clockwise till the color just appears then turn it back down till it just disapears (Black) do this for all three colors Now the set should runn

Picture is dark


sitnlisten - yes it does appear your pix tube is getting weak,but we may be able to turn up the flyback alittle to brighten up the picture.If you take the back off you will see the flyback-large black unit with a wire going to the round rubber cap on the back of the pix tube.Look at the flyback there are usually 2 adjusters one marked focus the other screen,just turn up the screen a little bit at a time.If you turn this up too much you will wind up with retrace lines on the screen.You may also want to check the pcboard ass'y for a sub bright adjust,and same thing small adjustments.If this don't help your pix tube may be too far gone.I hope this helps. cooltek Feb.1/08
