Surge killing LCD's?

Ash85 · 29-07-2007, 22:47

My boyfriend recently got a LCD TV and were chuffed with it.
Anyway he was talking to someone to his works about them and this person used to sell TV's and the guy said to always leave it on overnight, we do anyway but he said it was because every time you turn it off by the plug and back on it makes a surge or something and it is the main reason for killing people's LCD's.
I thought this was a load of balls so I though I'd ask if it's true on here, I thought the LCD backlighting was the main killer???
Hope someone can shed some light on this.

note to self "another reason why plasma is better than LCD"

That's rather premature considering there's nothing to back this up. Anyway There's plenty of reasons not to buy plasma that are far more convincing.

It's basically a load of balls! - but with a VERY, VERY, slight grain of truth in it. When you turn on ANY electronic item, LCD, Plasma, CRT, radio, VCR etc. you get a surge as it powers up, this is perfectly normal, and nothing to worry about.

However, it is true that most power supply failures occur as you switch on, whatever the unit is - and LCD is no worse than anything else for this, and certainly Plasma (or CRT) is no better in this regard.

The TV has a switch on it, turn it off using that switch.

Switch on surge for a Plasma is huge, followed by CRT and then LCD.

Switch on surges do stress-damage electronics, light bulb almost always fails at switch on you will notice, but most modern products such as LCD/Plasma TV's have soft start features embedded to counteract such problems.

So basically it's balls!

What the other people here have said is correct but I would also add that if there is a proper on off switch on the LCD (or any TV) that switching on and off at the wall does not create a surge at all.

Only if the switch on the TV is turned OFF, then when you turn the TV switch ON you get the same surge - so it makes no difference.

Another reason to keep stuff in standby.
