Did they say its the panel that needs replacing?

Is it completely dead ,can you hear the sound?

If you can hear the sound ,try glowing a flashlight and see if you can notice any picture.If you can see the picture ,then the backlight or the LED emitter needs to replaced or possibly the power supply mosfet for the LED emitters needs to be replaced.

Unfortunately it can happen to any make and model.Based on the complaints online Sony has lesser complaints then others but not by big margin.

I would be clued into this thread - AFAIK, this kinda problem happens to all of them. My friend had a 2.5 year old samsung - gone on the blink with weird white lines that would be seen at different points in the display at different times. Cost? 20k for motherboard, zero guarantee of any repairs. he had to buy a new one!

All this in less than one year.

Power Supply Board will be aprx 6500/- in needed to be replaced. Service centre charges extra.

No Sound , No picture. As per service centre, panel is culprit for sure. Also, panel is assembly of couple of cards plus screen, so they dont bother to check posibility repair of a component etc. We need to replace "Complete" part.

If there is no sound then it has to be the power supply board or the main image processing board thats gone.

Since if the panels goes wrong it has nothing to do with no sound.

My brother had this same issue with 32Inch Sony Bravia.
Cost of panel was around 18K. Sony was ready to give 50% discount and qouted 11K including everything. TV was 1 and half years old.

He bought a new TV as well.

LG quality has gone to the dogs.

Recently our 3.5 yr old Premium 500 ltr+ LG Fridge broke down - The door hinge mechanism broke and the door almost fell on my foot when I tried to open it.

LG denied all responsibility. Said buy a new door.

I had the old one repaired, and observed that the plastic of the fridge has become brittle and decayed. Horrible design. Horrible raw material quality.

Welcome to Pune, I too have a house there and have had my desktop go down due to brownouts and surges. All I can say is that please please use a UPS (offline) with sensitive electronic equipment in Pune. In 2011, there were 22 panels which went bust due to a brownout (very low fluctuating voltage & Cycles) in our society alone, there must have been a similar number across 7 societies which are fed by the MSEB line coming into our area.

Repair or Replacement may be the only option, since clearly manufacturers will not cover anything out of warranty. As far as electronics go, nothing can be predicted.
As a lesson for the future, always buy extended warranty for peace of mind. Most large electronics shop chains (Reliance, croma etc) offer it.

My 3 year old Samsung lcd had the same fate last month with weird flickering lines and what not, called samsung guys and he said panel is gone, repair cost to be 17k with not a single day of warranty.

Bought a new Sony led tv, gave the dead samsung to dealer for a buyback of 3k. These new breeds of led/lcd are not reliable, our 9 year old Akai crt still works flawlessly.

In my college hostels, the CRTs used to run 20x7x365 hours. And it lasted for about 2 years at least. This without any stabilizer.

Maybe the current gen TVs are unforgiving to variability in operating conditions.

Happened to my sisters 40 led Sony bought for 92k with one year warranty. Failed in a year and a half. Motherboard problem, cost of repair was 10k. This is main reason I buy TVs only in the grey market. Save the money to pay for repairs later. Any product will last a year at least, don't see a reason to pay for a years warranty.

Extended warranty !! It is a discussion topic altogether. LG charges 7000/- Per year for 42 inch. So in 3 years cost is already 21000/-. And i think you can enroll till 4/5 years only. So overall financial calculation doesn't fit.

As mentioned, I have dedicated digital voltage regulator specially designed for LED by V guard so it is not foul play of voltage.

My LG lcd had also died some time back. It is a 4ish year old model (when the initial 32 inch full hd panels had just started).
LG changed the power supply and motherboard for approx 7.8k and it was back to usual.
Post this, invested in a good quality UPS which supports undervoltage and overvoltage protection.

The UPS showed us that the power supply every single night would go to almost 270 volts in our house. Called MSEB, showed them the pics of the same, they put their own equipment for a day to check the readings, and next day they stepped down the voltage for the entire area to the proper 240 levels.

This is quite common. I managed video walls in previous life. Each wall had 9 panels. Averge life of a panel was around 4 years ballpark. This is across:

1. Locations
2. Brands
3. Tech (Starting with Plasma to newest ones being LCD with LED backlight)

For personal use, I have a 50 inch LG plasma TV. It stopped working in 3.5 years (TV cracked on its own). Since I had extended 5 Years warranty, it was replaced FOC. Issue was with most probably with C-Panel, it cracked the panel due to overheating.

If anyone is buying expensive TV (say 60k+), I strongly recommened extended warranty.
