TV Shuts Down

The TV will show a few horizontal lines then shut down. I have to wait about 1/2 hr and attempt to turn it back on. It may stay on or shut down again. It is not consistent. Any suggestions?

Why do my TV shuts down?


Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

When I turn on the TV with the remote or on the front, it comes on for a second and then shuts off. I was able to keep it on once, and all I got was a horizontal white and colored line across the TV, but...


horizontal lines indicates that the vertical section is most likely the defect..a defective deflection yoke could cause this and eventually damage the vertical output ic causing an overloading in the power supply then can caused to shut down

My tv was working perfectly then in the middle of my show it just turned off, when i turned it back on i could recognise my show through a thin horizontal line through the middle of the screen for less...


It is an indication of collapsed vertical deflection. Your vertical output IC might be shorted or have an open fusible resistor/yoke winding. It will automatically shuts down the unit to avoid damage to your tube. This is quite fixable and I've advice you to look for a qualified technician/repair shop to isolate the problem.

Thanks for using fixya.

TV shutting off automatically means its a problem with the Lamp. Contact Pioneer or any local tech shop or Best buy and get the same replaced.
Turning off after specific time : Go to the timer option and disable the Automatically Switch off option. This will resolve the issue. Please let me know if it worked. If you need the user manual or instruction manula please click on the link below

Intense white & coloured horizontal line on black background on startup


I wouldn't attempt as the capacitors on a tv store around 25000 volts this is more than enough to kill you and they keep there charge even when the tv is off. Either take it to a repair shop or put that money towards buying a new tv - Do not even attempt to open the tv. (It sounds like maybe a tube has gone or the electromagnet that makes the beam move vertically is gone.

TV shuts off and red standby/timer lights blinks red until I power the set off. When it shuts down it does so with a very loud snap. When I turn it back on the screen is blue and has light blue...


The most common cause for what you are seeing is a shorted gun in the picture tube. When 2 elements (heater and cathode) of one of the guns inside the neck of the picture tube touch, that gun goes full on and overloads the flyback (high voltage) transformer. If it is in the blue gun, the screen will go bright blue with light blue "retrace" lines in it. The computer senses the overload and shuts the set off. At 2 years old the tech most likely tried removing the short by arcing between the elements. This works sometimes but the short often comes back a few months later. Another attempt at removing the short could be tried, and it might work this time, but it may or may not work for long. The ony other solution is to replace the picture tube but that would cost much more than the set is worth. A qualified tech will be able to tell you if this is the problem in your set.
