That feature may require a box to be inline now-recently a lot of the settings for this feature have changed.

I see so many here with no sound/nopicture issues:


1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.5_3_2012_1_40_30_pm.jpg

If your TV is a month old call sony and get the TV serviced or exchanged. You are covered under warranty.

Go into your menu and look for Closed Caption. Turn it off. That's it!

capacitors on your power supply are bad. I normally remove it and replace, or send the old one totvpartsandmanuals.com and get a discount on a new one. You can get it c.o.d. or have the same one refurbished

Hello, sounds like it might be a problem with your lcd controller. I have included a link to a company that has been great to me in the past with all of my tv parts needs. Hope that helps!

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.
Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.

Thanks for using Fixya.

This is probably a bad capacitor, if the tv is no longer on warranty I would way look on the power supply board inside the tv at the capacitors, they are the round cylinders and the bad ones will have a slight bulge in the top or worse, a good spot to see a little more info is http://en.wikipedia.org/wiki/Capacitor_plague/

This is called "clouding". It is very common with a lot of the lcd panels. I suugest going to sonys e support website to see if it might still be under warranty. I have a sony lcd tv that I purchased back in 07 and its under warranty until october 2012. If it is still under warranty then sony will fix it for free.

If this set is under warranty you should return it to get it fixed/replaced. If not then;
This sound like the power supply board is failing. The electrolytic capacitors on the board may need to be replaced.
IF YOU KNOW HOW TO WORK WITH ELECTRONICS REPAIR(soldering ) or have a friend with knowledge/skill you can fix it.
>Unplug the set.
>Remove the back cover.
>look at the capacitors on the power supply board. If the top of any of them are bulging up that is the problem.
>You will have to replace ALL the electrolytic capacitors except for the large one.
> Use ones with the same farad rating

> Use ones with the same or higher voltage rating
> Use high temperature rating
> Install one at a time to prevent mix-up and keep the polarity correct.

> Leave a space between the PC board and the bottom of the capacitors for expansion. They heat up.

One source for some good capacitors is NTE. Try nteinc.com for a local outlet.
You can also search for other sources. Some companies even sell all the capacitors in a kit.

Total price of parts should be < $20.00

Probably a power supply - if you open the back of the tv (if you have electronic experience) find the power supply look for bulged capacitors and replace them - or if you have the part number of the power supply you can find one off the net - i have one for a sony 46kdl that may work if you give me the part number i can verify if this one will work. The part number i have is DPS-275MP-1 - let me know if you have any additional questions.


Sony Bravia... | Answered on Feb 06, 2011

You will need new screen and it will cost more than the new 42" TV.
LCD panel is the most expensive part of the TV and limited production part.
I would sell parts on EBAY (see www.shopjimmy.com to see how much yours parts are worth).
