You can get a repair shop to see if backlight is dead. If you can get it replaced by LEDs, it won't cost much.

Ok...will contact local guys through Justdial...Lets see what they reply

Display is gone means the PCB needs to be replaced/repaired.

The problem with LED TV repair is that it is not as trustable as CRT TV repair and is expensive.
With 26k you can buy another brand new 43" TV from reputed brand.

Mi TV qualities are not as good as other brands. One of my friend bought a newly launched MiTV from Flipkart in 2018 and within 6 Months the plastic of the TV broke and can further be broken with just finger tap. Quality is highly questionable in Mi.

Also, the local repair shop won't use the Genuine TV parts from Mi. Hence, its a grey area of repair.

It worked till 3 years, maybe try getting it repaired. If the fault is big and repair person asks for more than 4-5k better toss it because even after repair, chances of it getting dead are high.

Also, do you see any power led turn on or else try connecting a usb as this also seems to be problem in psu of TV.

After switch-on Led light on display is on...not shown video or picture...while pressing all button in remote...button audio sounds come

Can you share screenshots or video?

Buy new one instead repairing from mi service.
Local repairs are not good. You will end up spending more than official repair and more than once.

TV parts are hard to get and genuine parts are rare. Blame those manufacturers. You can find parts online but those from top brands.

If problem is with pcb then around 4k to 7k you will have to pay.

You are lucky that it lasted 3 years, I have read comments about people having their sony/samsung/lg tv giving up after 2-2.5 years, they just don't make TVs like earlier times nowadays. If it is just motherboard/pcb issue then you can get it repaired for 6-7k but if panel itself has developed issues then almost zero chances of repair. Even if it is 6-7k think carefully because in some good sale you can get 49" 1080p TV for as low as 23-24k after all the discounts.

TV manufactures put inferior quality part to make consumers buy TV every 2yrs or so.

I got my friend Hisense A71F 50" 4K TV with extended warranty for close to 27k last month during the sale, so definitely don't pay the money for display replacement.

See what local repair guys say.

After on the Bottom side power, light blinking and display is on...no picture or video shown

LCD screen is working fine. The only problem I see is the PCB chip which is damaged.

For finding backlight issue. Tap on screen or press screen gently.

Your problem seems common while searching on YouTube.

You won't have to pay more than 200-500. Unless part is replaced or repaired.
Record TV repair so you can argue for high charge.

Finally, one local guy come home and resolved....for 1500/-
Now all is good... But one-third of the screen display slight variation on the vertical color difference...only close range will only be able to be seen...

They told me If again problem raised...they have to repair the display by machine for 7000/- guarantee will be 3 months

Did he told what exactly was the issue?

RumbaMon19 said:

Nope

shreeux said:

Ask him what exactly did he charge you 1500 for.

shreeux said:
Nope

its important to know what he did. If he changed some components then he shud have not said that 7000 line.

And even chip level board repair(which is the max he can do) is not that expensive as soldering stations costs around 12-14k and 7000 k for a repair is way too much. Instead in 7000 u can get original pcb. Seems scammy to me.

he might had done some jugaad and certainly knows that it will not last long.

He must have replaced IC if charge is 1500. If not then 1500 is a lot for service charge.
He is checking voltages can be seen in image.
I think there must be carbon dust or connector issue.
It's good it is fixed. Enjoy.

Also how you find local repair.
I wanted to repair my TV too.

Just Dial...After searched...A lot of calls were received...Only one is speaking technically...Others speak as money-minded

He has done in front of me only....nothing changed...just remove all connectors...check with the multimeter...Hardly taken 20 mins

Carbon dust for sure. He must have cleaned all connectors. Or cut down some shorted path.

I watched this later... :sad:

Local repair guys charge too much. I still remember my Acer LCD monitor was showing no display. and the repair guy charged me Rs 700 and all he did was replaced the capacitor which was damaged.

Kya kaaare...Sabko paisa Kamana hai.

Next time I will contact here....cheap and best...

Saw ur thread today.

Display or backlit issue. What he did could be temporary fix.

Hi! Saw the tag today. After going through the thread, like everyone suggest, call back that repair personnel and ask what exactly he did to repair.

I saw the picture earlier. If the TV is working fine then you don't need to worry about it. But surely don't spend 7k anymore on any repair as others suggested.
