Question about Televison & Video

Open Question

I have an LG RZ-42PX11 42" Plasma TV, last week it started to flicker the picture for a min or so when switched on, now when it comes on, the picture is extremely grainy, accompanied by a loud buzzing that seems to be coming from the PSU. Picture flickers all the time now and cant get to full brightness. Anyone got any ideas ???

If the adjustments on the power board are correct and if you are not at high altitude, the plasma display panel is defective. If the set is off warranty, it is not cost effective to replace the display panel. If it is off warranty, you should give the manufacturers Customer Relations a call. The phone number is usually right on the back of the tv. The manufacturer of the tv might make a warranty concession if they are concerned about their brand reputation. Some manufacturers find it less expensive to just switch brand names rather than make good on defective products. If all else fails, you might get some money back by selling the circuit boards on eBay.

LG LED TV has sound but no picture. Went out all of a sudden. Image shows with flashlight. Flashes for split second on power up and power down.


Your screens back light has most likely failed and or the voltage controller for the back light, both should be replaced.

My lg plasma tv is cutting off the edges of the shows we are watching. I cant find a setting that will take care of it. Can you help


hmm normally these settings are found in the picture settings of the set top box or just a setting in the tv's picture settings now there might be an option to say fill screen that may work best for some or leave the tv in 16:9 some broadcasts may only be in 4:3 at times this is normal broadcasting and not much can be done unless the setting on the picture option is set to fill screen

I have pioneer plasma tv about 6 years old. I turned the power on, sound but no picture. Do you think it is worth fixing?


no
plasma tv units consume considerable power and the latest led units don't so for the extra cost of a new unit , there will be a power saving over the years

I have a toshiba LED TV Model 40PB200, i bought it two months now. Recently, the audio in port started producing a sound as if microphone is on and the VGA for computer flickers when i connect a laptop on...


One thing is that unless it is usb you should always have the devices powered DOWN before connecting them via" wire electric data cables". it only takes 3 static volts of electricity to damage a circuit board. when you zap you buddy when you wear sox its 20 to 30,000 volts of static electricity so 3 volts would not be known let alone felt or seen. Power down and you will be well not you .
