LCD tv gets pink/blue lines, makes LOUD buzzing noise

Very intermittent problem: TV makes a VERY loud buzzing noise, and blue and pink vertical lines take over the LCD screen. Can't operate tv controls or even turn it off at first; but after a few tries, I can turn the tv off. When I turn it back on in a few seconds, it's completely fine again! (Westinghouse brand)

It's been happening very intermittently for a few months.


Thanks in advance!

check your power board, most likely that's the part that is causing the problem.

SOURCE: Vizio makes loud static noise, picture goes fuzzy.

You should check your home wiring and grounding. Also be aware of anything that has recently been turned on when this happens. Anyone using a microvwave, cell phone, or other appliance that might be causing the interference.

SOURCE: LOUD BUZZING/HUMMING SOUND- CAN HEAR OVER AUDIO

have someone check speaker ground to the TV chassis. Your speakers are picking up reverb from the Video Signal.

Tv making loud buzzing noise


A common cause are failure of decopling capacitors in the audio section, and or the circuit board power distribution that feeds the audio board. Most of the capacitors are surface mount components. The standard fix is to start by changing the circuit boards that have the defective parts.

If the set is under warranty, call for warranty service. Out of warranty service is expensive for these TV sets.

My LCD TV's audio is making a loud intermittent static buzzing noise.


A test you can make is remove most of the gear that is connected and start with just the cable and no box connected--run to see if issue happens-

Add more equipment until issue appears again--try this way to see what unit is causing this---if nothing but a DVD connected and it does it--its in the set--if not a time consuming thing but only way to see which piece of the equipment involved is the problem.

JVC TV LCD Model LT-42PM30 intermittant buzzing noise


Most likely suspect is the power supply board---transformers on that board can and do vibrate hard enough to cause this.

At our shop we either locate the part creating the sound and treat it to hot blue to muffle and remove the noise or if confirmed to be on power board--REPLACE THAT BOARD.

It has a loud buzzing noise how do I fix that problem?


It appears that your connections are not correct. Please switch off the TV. Disconnect all the cable. Wait for some time. Reconnect cables one by making sure you strictly follow the color code i.e. that red pin cable must go in the red socket. After all the cables are connected switch on the TV. Loud buzzing noise is due to wrong connection of cables especially the Earthing/Neutral

Loud buzzing noise on vizio tv


It sound like you may have sound processor problem which is part of the main board, I would also look at the 12vdc from power supply to make sure it is clean DC.
