Sony Bravia KDL-40Z5100


PCMag did not test the 40-inch Sony Bravia KDL-40Z5100. We did, however, test and review the 46-inch KDL-46Z5100 from the same series.

Horrible Reliability. Sony Customer Service Is TERRIBLE


Talked to many "customer service" types and all told us that basically we were out of luck. Unknown how long these 2 inverters will take to come in but so far without a 1250.00 for 4 weeks now. Side note. The replacement panel is made by Samsung and...

Picture is good. When the TV worked it was fantastic. Worked for about 5 months and then would not turn on. Called Sony as it was still under factory warranty. Sony customer service referred us to one of there "approved" repair companies

Waited 4 weeks for the replacement panel to come in and then still didnt work. Turns out its something else. Sony told us that if it had been w/in 30 days they would replace. since not too bad. We have to wait for part or accept fact refurbished

Great overall T.V. for the price.


Unfortunately, I had an issue with this T.V. 1 month (and 5 days) outside of the 1 year manufacture's warranty. While still covered by insurance through my VISA card, I decided to give SONY a chance to stand behind their product, even if out of...

Excellent T.V., Great Picture, Good price (especially when compared to the XBR flagship model), Easy to use menu. Customer service experience with Sony was very good

T.V. began turning "resetting" itself every 5 minutes 13 months out of warranty. Faulty "BU Board" needed to be replaced. A $550 repair

One Of The BEST LCD TV's On The Market


I like having the ethernet port that streams movies right from Netflix to your TV. I also a have a Sony Blu Ray player that does the same thing. The Z Series also got the 240MHZ refresh rate that blows away most LED sets on the market as well as the...

This is the best LCD TV's on the market. It's got all kinds of great features you can read about on cNet. I upgraded to this Sony 52" TV from a really nice Sony 40" set. This 52" Z Series has terrific sound, picture, features, and viewing angle

No CONS that I know of
