Hello. I have a Sony Bravia TV (kdl 40v5500) that doesn't turn on, though the LED blinks 7 times. Help me to solve this problem. Best regards.

Hi there,

I've been looking into this myself as I've also recently purchased the KDL-40W4000. I was watching a murky old film and was getting a bit of sludgy ghosting but found that by reducing the contrast to 25, setting the backlight on low, colour on neutral and the brightness about 40-60 (and taking ALL advanced noise functions off), this reduced the ghosting considerably.

BUT, this is quite a cool and dark image. If you watch standard TV and films mainly, a variation of the Cinema setting is probably the best overall setting i.e.

backlight: min
contrast: 79
brightness: 50
colour: 53
colour temp: Warm 2 (although Warm 1 is less yellow and still fine)
sharpness: min
noise reduction: off
mpeg nr: off
contrast enhancer: off
colour space: standard

This can indicate a problem with the high voltage circuits. Since this is a new set, it should still be under warranty. DO NOT open up the unit as that will void the warranty. Return the set or request warranty service. Note the 8 blinks when you request service as that should allow them to bring the correct replacement parts.

Keep us posted.

Hello,

Unfortunately, this is a failure of the balancer board for the backlight. The unfortunate part is that the balancer is not available by itself anymore, and the whole panel must be replaced, as Sony only has the balancers attached to new panels. You can contact Sony directly to ask for assistance, and it usually helps.

Hope this helps you...

I just worked on this last week 13 blinks means there is a problem with the backlights.So it can be 1 of 2 things bad inverter board( which costs less than $200) or the panel in which case you can thow the TV away as it will probably cost as much for a new TV.Unfortunately the set I worked on ended up being panel. If you try the inverter board just take your time removing it its plugged in rather tight I gently tapped it out with a screwdriver to get it started.

It's a power supply related issue. It's an error code for a certain circuit pathway, but I'm not sure 100% sure what code 13 can be because I don't have the Service Manual for your exact TV model number. But, here's where you can get one:

It will have all the info on the trouble codes for your TV. Schematics, Diagrams and Part number list for repairs.
