<!-- from fixya rte -->What makes plasma tv keep cutting off - Zenith P42W34P 42 in. EDTV-Ready Plasma Television

need more info is that watchin tv or usb connected is it lcd or plasma if plasma its because its 5yrs old mae gassingy need r

reset it to factory

Yes it's. Just bring it 2the nearst electronic shop for repair. T power my be spoile or some insect get inside n make it burn. It's ever happen 2 my tv also.

The main board have some shorted component/s in the circuit. your set need a through checkup. Contact any experienced service technician.

Check the contactor contacts for pitting. if severly pitted, replace contactor. If a death grip on the switch makes it work better then a light touch- replace the trigger switch.

usually this is a fault with the power supply in the tv. the capacators only hold enough charge to turn on the tv but not maintain the proper current to keep it on. contact a repair technition or the manufacturer.

It not the tv,u restart the Sky HD box the signal come back right?The Sky HD box is the problems,replaced the box,u will solved this problems.

You can not install anything that is not specified by manufacturer. All you can do - make sure your TV have enough "breathing" room on it's back , top and sides. All Plasma Panels produce a lot of heat - it's "normal" operation. If you still unhappy with it you can put regular household fan on the back of the TV. I doubt that it would make any difference though.

Check Power supply board and y board

There are a few things about plasma cutting safety that are different from general welding safety tips This short list of plasma cutter safety tips is geared toward light duty plasma cutting using compressed air not large industrial units that use gas mixtures and water cutting tables. Electric Shock Can Kill - Operating a plasma cutter completes an electric circuit between the torch and the workpiece. The workpiece and anything touching the workpiece are part of the electrical circuit. - Never touch the torch body, workpiece or the water in a water table when the plasma system is operating. Voltages & Currents - Plasma cutter output voltages are much greater than welding voltages, usually 100-200 volts. Precautionary Measures - Do not pick up the workpiece, including the waste cutoff, while you cut. Leave the workpiece in place on the workbench with the work cable attached during the cutting process. - During plasma cutting operations do not move the work clamp. Wear insulated gloves and boots, and keep your body and clothing dry. - Do not stand, sit or lie on or otherwise touch any wet surface when using the plasma cutter system. - Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the work or ground. If you must work in or near a damp area, use extreme caution. Work Cable - Ensure metal-to-metal contact between work cable and workpiece or work table. - Work cable clamp should make contact with clean metal free of rust, dirt, painted surfaces, etc. - Do not attach work cable to the piece that will fall away when the cut is complete Plasma cutter Arc Rays Plasma cutter arc rays produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Protective Clothing - Guantlet gloves, safety shoes and hat. - Flame-retardant clothing to cover all exposed areas. - Cuffless trousers to prevent entry of sparks and slag. - Remove combustibles, such as a butane lighter or matches, from your pockets before cutting. Noise Levels of Plasma Arc Cutting - Plasma arc cutting systems can generate noise levels in excess of 120 dB during high-amperage cutting operations. - Ear protection should be used when operating or working near plasma arc cutting operations. Toxic Fumes & Gases Plasma arc cutting can produce toxic fumes and gases that deplete oxygen and cause serious injury. - Keep the cutting area well ventilated or use an approved air-supplied respirator. - Do not cut in locations near degreasing, cleaning or spraying operations. The vapors from certain chlorinated solvents decompose to form phosgene gas when exposed to ultraviolet radiation. Pacemakers & Hearing Aids - Pacemaker and hearing aid operation can be affected by magnetic fields from high currents. Pacemaker and hearing aid wearers should consult a doctor before going near any plasma arc cutting and gouging operations Overall Plasma Safety - The plasma arc cutting process can be very safe. - By paying attention to safety standards and correctly setting up and operating the system, plasma arc cutting poses no more a threat than most welding processes.
