    Sony kdl-50w829b blue light circled arrow

    Hi i had problems getting this tv to turn on now on I'm having a problem with doing anything at all. I downloaded the latest software onto a usb stick and left the tv hoping it would resolve the issue after 2hrs its still the same. Any ideas???

    Does it give a flashing fault code at all?

        Solid blue LED usually means it is functional and hasn't detected a fault. We need more information. I assume you press POWER ON and it changes the indicator LED from Red to Blue? Do you get any sound? Does there appear to be any response to the remote control?
        From what you have told us it appears the Standby 5 volt supply is operational.
        What do you mean in your description line when you say "circled arrow"?

          I see this is a fairly new set with Smart TV functionality. My experience has been that sometimes these Smart TVs aren't so smart and get caught in software loops at start up. I read a review that was critical of just how long this model takes to come on-line after you press the power on button. I'd be starting to suspect a software problem. A new set like this is unlikely to be hardware. Be interested to see what others on the Forum think? But you've tried a software re-flash without luck so I don't know what more to suggest?

              Look at Ebay theres many different main boards listed for this model. Is there anyway of knowing which one is the right one

                not with out taking the back of the tv really then on the main board you will find some numbers printed on it also on a sticker as the board really needs to match the panel used on the set.

                    Sony`s normally start with 1-88###### with main boards
                    So look for that number
                    P.s are you sure its the main board at fault ?

                        by budwich
                        Got this projector which has a problem with a lack of blue. Menu text is very yellow... expecting white. If I input a signal from a test disc via hdmi, a red screen image shows a uniform red as expect. Green similar while the blue does show but with non-uniformity. Looked at the in-polarizers. They are all good and clean. Running the projector to expose the light area in the prism block, shows each color well represented, all looking about the same intensity from the naked eye. Looking at the prism block itself and sending a light source back into the "out port", the individual...

                        Hello all. Sony XBR-75X800G - Android start up only and dark blue screen. Back lighting works. Music just repeats itself. Remote has limited function. Ive search for model # here but I did not find anything. Thinking its T-con but I dont have what type of numbers Im to have when reading on a MM. Any help would be great. TV is 5 years old. Thanks
