    I have a Sony Bravia KDL-46S4100 46" flat screen TV that has screen problems. I have heard that Sony has provided a 3 yr. warranty for some of these KDL models that have had catastrophic failures in the first 18 to 36 months of service. This warranty is in addition to the normal 1 year mfgr. warranty that is standard on all sets. How can I contact the Sony warranty / service personnel that are authorized to process this warranty claim for me? Their authorized service tech says the panel is shot and I have since been given an event number that has been issued by the Sony Customer Service organization themselves. What do I do next and who do I talk to? I fully expected my Sony to last a lot longer than the 22 months I had it before it started malfunctioning. Is there a mailing address I can write to in order to send a certified letter to a Sony Customer Satisfaction organization or person. This FixYa site has 290 Sony events listed while Toshiba has 10 and Samsung has only 9. Sony definitely has a major problem with their flat panel TV reliability and they need to come clean with their customers. Our local Best Buy does not carry their brand anymore and the local HH Gregg has only 2 of their models on the floor. It appears that the retailers are shying away from Sony products due to their knowledge of Sony's inherent problems. We all have spent a lot of money on these flat panel televisions and Sony needs to stand behind their products.... no matter where they are manufactured.
    I will appreciate any assistance and will post my results in the near future. If you are in the same boat please comment on this post and maybe we can present Sony with a united front and get some action. Thamk you. Russ

Sony 52xbr4 screen flickering

Fault with the main power supply regulator board. Ubnormal DC voltage output from it. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and precious time.

Sony bravia lcd tv 40 inch

I have a Sony Bravia 46'' TV. I bought a Universal WiFi Adapter from Walmart a few years ago for about $50. You have to plug it into the Ethernet port on the Bravia using an Ethernet cable (the other end of the Ethernet cable goes into the Ethernet port on the adapter). The adapter needs also a power outlet. I do not remember if the adapter came with the Ethernet cable (likely) or I had to buy it separately.

Before buying the adapter make sure that:

1. Your Bravia has an Ethernet port (on my Bravia it is in the back of the TV), and
2. You have/use a wireless router for your home network.

Hope this helps.

I have a Bravia KDL-52W4100 and the screen is starting to flicker when watching TV or DVD's, but not when I am in one of the Menu's.

I have seen about a dozen questions here in the last ten days with several models with the same type of problem, Sony of course says they are not aware of this issue---typical for them to deny until smoke turns to fire.....

Tv turns on then goes off

Fully powers off or stays on with Sound on?
Sounds like something wrong in your power supply.
I believe Sony has a 2 year warranty?
Is it older than 2 years?

I have the same TV; the 52" XBR9. I bought it also a year ago. I am having the same problem. My TV flickers, images are double and tripled sometimes. But if you hit the TV on the back, not to hard, it fixes the problem. I am having a technician come on down to my home to take a look at it. My manufactures warranty is ending in three days. Thank god it had happened before that. The TV is mostly the problem here and not your cable box.
