This is not a problem with the display at all - the display panel is just fine. The problem is with the signal route. Could be anywhere from STB internals to connecting cable to TV internal path on board for signal.

First, take out and reconnect the cable connecting the STB to the TV. If that is fine, if you have another TV, or can borrow a small one from somewhere, check if the STB is giving a problem. Last resort, call Sony service again and tell them the problem is with signal intermittence on the board.

I came back from service center with the TV without getting it repaired. They have quoted a price of 25k for replacement of whole LCD panel. When I asked them whats the exact fault, to which he replied that it could be a fault with one of the connectors. So next obvious question was, where exactly and his answer was, we dont have that much expertise to find small faults. So we'll replace the panel.
This left me wondering that even if the charge for fixing that fault might be ₹500 but since they can't find it, they'll make the customer pay 25k for the same! As it is, the TV is out of warranty so will ask local Repairman to check. Lets hope for the best.

It is most probably in the TV decoding circuit that outs the video for the display. If your display was gone, the menu and no signal message would also blink with the blue flashes, wouldn't they?

Try the old composite cables to see if analog input works. Try with other HDMI inputs (if equipped) on your TV.

If you watch the video, you'll see that I had switched off the input (TataSKY) but the problem was still persisiting. Lets see what's the exact fault today. Will keep updating here.

There was a problem with my Samsung 40". Samsung gives me a quote for Rs 9000, in which "labour" is 6000 just because the TV was imported! Technician tells me if the same model was bought from here it would work out to 1200 labour charge!

Nevertheless, gave it to a guy I knew who fixed the power unit and its working fine now.. all for 3000

Final diagnosis on my Sony Bravia BX42 40" LCD is that the panel is gone. I complained to higher ups in Sony through Facebook and Twitter and they contacted me yesterday. Lets see where it leads to now. If they don't give me a reasonable option, i'll not get it repaired. It'll be good to add ₹5000/- to their estimate of ₹25K and buy a new television set rather than sticking with a repaired set.

Hi

I had a control unit blow, for the second time, on my Samsung 46" LCD.
Searched the net and it's a common fault across brands. The heat sinks give up after a year, which is just out of warranty. The metal plate covering the control unit only helps in the overheating process.

The first was replaced by Samsung for about Rs 4000 approx. (Part + service charge)

The second time it blew after another year or so. Seems like an annual feature.

Samsung said:
1. We are looking for part
2. It's Diwali so technicians are not there (fair).
3. Part not available (more than a month has passed)
4. Change the entire LCD panel for Rs 35000 since it comes as one unit instead of separate components.
5. We have announced a cash back scheme. We will pay your money back since we can't find the part.
6. Oh since your TV is 3+ years old we can offer 45% of bill value.
7. We are looking for parts but looks impossible.
8. That's the best offer, sorry.

So I took down the part number printed on the control board and googled it.

Found a manufacturer in China, Aoi, who still makes it. Figured that they deliver through Ali Express and ordered 2 boards. Rs 8200 including shipping and customs.

One I got a Samsung tech to replace (service charge Rs 1200 approx)

The other is safe as a backup.

Prepared for the annual blow out because of overheating and due to bad design.

And I refuse to spend Rs 1 Lakh or more, every 3 years because that's how long the LCDs or LEDs are 'supposed' to last.

I had persued this matter with higher ups at Sony India through Facebook and Twitter and they contacted me after a few days of venting my ire. After hearing me out and my issues, they reduced the price of repair to INR6500 for the whole panel. I was happy considering it was at a much reduced price.
As posted here, my TV was sent for repairs at a reduced price quoted by their East zone head. After about a week of giving my TV at service center, I got a call from regional head stating that they will not be able to repair my set as the spare parts are not available but in return, they would exchange my LCD with the next possible upgrade that happens to be a LED. I had deposited a DD of the said repair amount and today, I got a brand new replacement TV. Sony India does know how to keep its customers happy.

M samsung 46 inch lcd which is only 3 years old ,is having horizontal lines which are not too clear, fully across the panel.Could it be anything wrong with the panel itself or something related to the cables?If anyone can throw some light into this it would be most welcome.

Just watching the World-cup Opening ceremony and you know what I realized, there is no sound. And that's ruining the whole fun. The TV has to be on mute, as everyone at home is sleeping . How can one watch Fifa World-cup muted?

Now, I have a set of blue-tooth headphones, which I use with my phone for music. My tv is a Sony EX500, which is not blue-tooth enabled. Is there any way I can make it blue-tooth enabled, so that I can use my headphones?

What I have done after my son was born, I've connected an FM transmitter bought off eBay to the headphone jack. I tune my phone in, nothing to bother anybody.
Total cost, about 500 bucks, phone not included...

[mashmash]

Yes that's one option. Saw one on eBay costing a grand. How's the sound quality?

About as well as what you get from FM.... Stay within 10 or so metres, all good.
