TV Repair & Installation in Delhi

Look at the standby light before you book. Samsung's support guide reads a steady red light as a sign that the TV is getting power, and a blinking one as a possible problem inside the set. Lights differ by brand, so treat this as a first clue.

Light on, no start. Press the power button on the TV itself. If the button works and the remote does not, the remote is the likely fault, and the TV may be fine.

No light at all. Unplug the TV for 30 seconds, then plug it straight into a wall socket you know is working. Samsung advises leaving surge protectors out of this test, as they can degrade and stop supplying the right voltage.

Still dead. The power board is the next suspect. It takes the mains supply and feeds the rest of the TV, so its failure can look like a completely dead set. Book the ₹249 Power issue check-up. If the socket supply is poor, a new board may simply fail again, so the socket gets tested too.

Black screen with sound. Rule out the input first. Samsung's guide says a black screen can simply mean the wrong source, or a connected device that is off.

Next, try a torch in a dark room. Hold a phone torch close to the screen at an angle. If a faint picture shows, the panel is probably still working and the light behind it has stopped. This check usually works but proves nothing on its own, as a board can cut the backlight too.

Lines on the screen. Lines do not always mean a dead panel. LG lists a video signal problem from a set-top box, a loose or damaged HDMI or antenna cable, and a wrong aspect ratio among the causes. So run the built-in picture test first.

On newer LG TVs it sits under All Settings, Support, Screen Self-Diagnosis. On Samsung TVs, look under Support, Device Care, Self Diagnosis. LG's reading is simple: if the test image looks normal, check the cable and the connected device. If the lines appear on the test image too, the TV needs inspection.

Dark patches and cracks. Dim areas usually point to backlight strips, or to pressure damage on the panel. A cracked panel cannot be mended, only replaced. LG does not treat a small number of dark or bright dots as a defect. Book the ₹249 Display issue check-up for any of these.

Some of these faults need no spare part, and a few minutes of checks can save you the ₹249 visit. For no sound, check mute and confirm the sound output is set to the TV speaker. Then run the sound test on a Samsung TV, found under Device Care or Support, then Self Diagnosis. If the melody plays cleanly, the speakers are probably fine and the fault may sit in a connected device.

For a dead remote, use your phone camera. Point the front tip of the remote at the lens and hold the power button. If you see a flash on the phone screen, the remote is sending a signal. If not, change the batteries.

For Wi-Fi faults, restart the router and see if your phone connects. If the phone connects and the TV does not, book the check-up under Not sure or more than one issue.

Delhi's single-phase home supply is 230 volts, and DERC's supply rules allow 6% either way at the point of supply, about 216 to 244 volts. Whether your TV needs a stabiliser depends on the model, so read the voltage range on its back label or in the manual before you buy one.

Storms are a different problem from low voltage. LG's monsoon advice is to unplug the power cord when thunderstorms or lightning are forecast, and never to touch a power outlet during one. LG's warranty terms exclude power surges, dips and thunderstorm activity, so a board lost in a storm can turn into a paid repair.

If the socket supply looks wrong at the check-up, complain to your power company and keep the complaint number. BSES Rajdhani (19123) serves South Delhi and West Delhi, BSES Yamuna (19122) serves East Delhi and Central Delhi, and Tata Power-DDL (19124) serves North Delhi and North West Delhi. Your bill names the company. If only one room's sockets misbehave, book FixThat electrical services for the wiring.

Heat matters as well. Safdarjung touched 45.1°C on 19 May 2026, while one LG manual gives 40°C as the top operating temperature. A room is usually cooler than the outdoor peak, but a TV boxed into a tight cabinet on a top floor has less margin. Keep the vents open, and leave the 10 cm wall gap that manual asks for on a table stand.

In the monsoon, LG warns that higher humidity raises the risk of electrical leakage, and says to replace blackened outlets and damaged power cords immediately.

Check your purchase date first. If the brand warranty is still running, go to the brand before you book anyone else. LG's terms, for one, exclude damage from unauthorised repairs, so an outside repair can cost you the cover. Warranty cards differ by model, so read your own.

A power board or backlight repair on a newer TV is usually worth doing. Think twice with a cracked panel on a small set, or a model too old to find parts for. A panel is usually the costliest part in a TV, so put your written quote next to today's price for a new set of that size.

Before you approve, ask which part is being changed and where the work will be done. After a FixThat repair, the work carries a 30-day warranty. If the same problem comes back within 30 days, contact support from your booking and keep your invoice. FixThat is run by ProNearMe, which means one booking system, one price list and one support team. The about page has more.

If you do replace the TV, do not leave the old one with someone who will strip it for parts. The Central Pollution Control Board warns that e-waste can harm health and the environment when it is opened up unscientifically. Ask the brand or your dealer about take-back, or use a registered recycler.
