Does leaving the TV on standby wear it out or waste a lot of power?

Neither, in any meaningful way. Standby draws a trickle of power and keeps the boards slightly warm, which in Nellore's humid months is mildly good for them. Switch off at the wall when you are away for days, and always during thunderstorms — but the daily standby habit is not what shortens a TV's life.

Is it true that LED TVs get screen burn-in?

LED LCD TVs do not suffer permanent burn-in the way plasma and OLED panels can. A channel logo or a paused frame may leave a faint ghost for a while, which fades with normal viewing. If a mark on the screen never goes, it is a panel defect or pressure damage, not burn-in, and no amount of 'pixel refresh' video will shift it.

How often does a TV need a service?

A TV has no consumables, so there is no service in the way an AC has. What it needs is a yearly look: dust the vents and clean the screen properly, check the HDMI plugs for corrosion, check the bracket for rust or rocking, and replace the surge protector if there has been a bad storm. Ten minutes, once a year, after the monsoon.

TV myths that waste money, and what actually makes a TV last

Standby, screen cleaners, stabilisers, burn-in, brightness — the common TV myths in Nellore homes, what is true, and a yearly routine that extends a TV's life.

Most of what goes wrong with a TV in Nellore is the backlight and the power board, and most of what people do in the name of "looking after" the TV has no effect on either. Some of it does harm. Here are the myths we hear most, what is actually true, and the short list of habits that genuinely add years to a set.

Myth: the brighter the picture, the better the TV is working

The "vivid" or "dynamic" mode that shops use for demos drives the backlight at or near maximum. At home, in a normal room, it is too bright, and it is the single biggest thing you can do to shorten the backlight's life. Use "standard" or "movie", and set the backlight to the lowest level that looks good in the evening. A TV that dims over the years on full brightness is not "getting old"; it was run hard.

Myth: glass cleaner is fine for the screen

It is not. Screens have a coating that ammonia, alcohol and household sprays damage, leaving cloudy patches that do not come off. Use a dry microfibre cloth for dust; for marks, dampen the cloth slightly with plain water, wring it out, wipe gently, dry. Never spray anything at the screen, and never let liquid run to the bottom edge where the panel's driver strips sit.

Myth: a TV needs a stabiliser

Not for the usual voltage swings; a modern TV's power supply handles a wide input range. What it needs protection from is the spike — when power returns after a cut, and during lightning season. That calls for a proper surge protector with a working earth, and the plug out of the wall in a thunderstorm. A stabiliser alone does not catch a spike.

Myth: switching it off and on a lot damages it

The power board sees a small surge each time it starts, but it is designed for thousands of starts. What does wear the set is leaving it on for hours with no one watching. Switch it off when the room empties; that saves far more backlight hours than any worry about the on-off cycle.

Myth: a dead pixel means the panel is dying

A single stuck or dead pixel is a defect, irritating, and usually stays exactly as it is for the life of the set. It does not spread. Lines, blotches and growing dark patches are a different thing and are worth a diagnosis visit; one dot is not.

Myth: "no signal" means the TV has broken

It means the input the TV is on has nothing coming in: the set-top box is off, the HDMI plug is loose, or the input has been changed. The TV is working. Check the source button and the box before anything else.

Myth: LED TVs get burn-in like the old plasmas

They do not. A channel logo can leave a faint ghost that fades with normal use. A mark that never fades is a panel defect or pressure damage, not burn-in, and the "burn-in fix" videos do nothing for it.

Myth: a TV in a closed cabinet is protected

It is cooking. A closed cabinet traps the heat from the TV, the set-top box and the router in one small pocket of air, and in a Nellore summer that pocket gets well above room temperature. Heat is what ages the backlight and the capacitors on the power board. Open the cabinet, or take the TV out of it.

What actually makes a TV last

None of this costs much, and all of it targets the two things that really fail.

Every day

Sensible brightness, standard or movie mode.
Off when nobody is watching.

Every week or two

Dust the screen with a dry microfibre cloth.

In a thunderstorm

Plug out of the wall, dish cable out of the set-top box.

Once a year, after the monsoon

Check	Why
Dust the vents at the back with a dry brush or cloth	Dust plus humidity becomes a conductive film on the boards
Pull and inspect the HDMI and USB plugs for green crust	Corrosion causes flicker and "no signal"
Look at the bracket for rust and rocking	Coastal salt air gets to steel fixings
Check the surge protector is intact, replace after a big storm	A protector that has taken a hit protects nothing
Clear the smart TV's unused apps, update the firmware	Stops the slow-down before it starts

Always

A hand's width of air behind and above the set.
Out of direct sun, off a west-facing outside wall if possible.
No one lifts it by the screen, and nothing leans against it.

When a habit is not enough

A picture that has dimmed noticeably, a screen that flickers at low brightness, a standby light that blinks after a power cut, or a TV that restarts on damp evenings — those are faults, not maintenance. Most are the backlight or the power board, which are ₹499 and ₹350 on the rate card for diagnosis and labour, plus the part at MRP shown before fitting. Catching a flickering backlight early, before it takes the driver with it, is the cheaper repair.
