Re: sony bravia lcd klv-37s400a restart
Do you have a camera... can you take pictures of the inside of your TV?
Notice you live in Cote D'iovre, so how easy will it be to get parts? Do you have many electronics shops/distributors?

Re: sony bravia lcd klv-37s400a restart
"when it starts, it stays on moin one minute and turns off. he does it restart only" look like the digital mainboard is bad (its control on/off and TV function)
open the TV & take picture and pot this thread |

Re: sony bravia lcd klv-37s400a restart
Hi- Pictures need to be a bit sharper
Examples of what is needed http://www.badcaps.net/forum/attachm...1&d=1290283049 http://www.badcaps.net/forum/attachm...7&d=1280167246 It will be useful if you can say a bit about yourself - skills tools etc Do you have a multimeter and can you use it?. Can you do a picture of the inverter board - one down left side in pic 1 Do it in 2 halves - overlap When you switch on does the screen light up then go off. What do the LEDs do - stay on/ flash/ change colour "he does it restart only" what do you mean? Does it try to restart after it goes off.

Re: sony bravia lcd klv-37s400a restart
in fact I am a technician and I'm used to depanner.Mais it is now that I work on LCD, PLASMA. Also I have a multimeter that I know and use lots of other equipment. I want to distinguish from other technician here because they do nothing but tinker. Otherwise when you turn on the screen, it stays on for a miniute to moin and he died. and after two minutes, it turns back on then back off. no flashing LED to assert an error code. thank you

Re: sony bravia lcd klv-37s400a restart
I had a 40W4150 which restarted like three times and then it gave me a 10 blink code. I have reset to factory, did a firmware update and stopped doing that.

Re: sony bravia lcd klv-37s400a restart
@Mady - I think I was on holiday and missed following this up. On the inverter board
there is at least one fuse that I can see - did you test it? |

Re: sony bravia lcd klv-37s400a restart
It might be done with the USB port. Maybe Sony has firmware on their website.

Re: sony bravia lcd klv-37s400a restart
@milha My post was directed at MADY but if you look at MADY's picture 3 there is a small white fuse just above the connector. It is at F4 which might suggest there are other fuses on that board. Do you have a different board?

Re: sony bravia lcd klv-37s400a restart
On the model that I have worked I had to hold the arrow up from the remote while I turned the TV on from the TV's power button and then let go the arrow up button.
