    Sony KDL-50R550A

    This TV was under warranty, i was reimbursed the value of the TV, now i want to try to repair it as the warranty company gave up on it and said i could keep it.

    I have no access to the service manual, sony sells it for 20 bucks though.

    The unit would turn on then 2 seconds it would turn back off into standby and blink 6 times.

    The repair company came out and replaced the power supply, plugged it in, same 6 blinks.

    Left the new PSU in and placed a new main board in, fixed issue.

    Now the unit has a "dead" led or dark spot in upper left hand corner.
    As well when the screen first turns on there is a unsettlingly loud coil whine coming from the area the dead led is in. Upper left from front.

    I assume it is a dead led, i would like to try to repair it.

    What should i expect?

    I have a fieldpeice HS36
    and a fluke 81438
    MY soldering iron broke and i ordered a new one should be here in a week. I have a solder hand vacuum.
    I also have access to a heat gun.

    Im new to the tv repair side of things, ive read up a bit on where to obtain small components here and there.

    Any help would be greatly appreciated.

    The only other topic i found was here

    I figured instead of derailing superg's post i would begin my own.

    SONY KDL-46R473A ALMOST DEAD NO STB
    by bohaboha
    Hello to everyone in this wonderful forum.
    I have this SONY LCD TV KDL_46R473a
    PSU GL5 APS350 :1-888-122- 12
    MAINBOARD FY13_EU IP-012C101-4010
    black screen ,no STB no life almost death.
    on PS all the required volts are present 394V on the main cap and those on cold side 12.41V,3.45 and 3.45 are on
    Also 3,5,and 12v are on.
    nothing happens if i disconnect the PSU from the mainboard as on Samsung because here i think the mainboard gives the signal to the ps.
    don't know what to do next all suggestions and advice are very welcome​...

    Sony 55W905 dead
    by Talyn
    Hi,
    My Sony W905 started to turn itself off an on every few minutes and blinking 8 times red in standby. A few minutes later the tv was completely dead.
    I can only hear the click of the PSU when attaching/detaching the power cable. No standby LED.

    Any advice? Thanks!

    Sony KDL-55W755C - Dead
    by mrsith
    Hello again lifesavers.

    I have a KDL-55W755c that came in dead - not even standby light going on. Tested the power supply - all correct. Tested the output pins on the Led driver board (in which the power cord plugs in) - all seemed fine.
    I got a service manual for this model and tested the DC/DC converter by checking voltages on selected components. Every voltage was present where it should be. Service manual says that in this case a "Muffin" replacement is needed. This is the moment where I got stuck as I wasn't able to Google my way through it - till this day I...

    6 Red Blinking lights (left side darker) on Sony KD-49XE8396
    by Watson306
    Hi,

    I've got a Sony KD-49XE8396 TV that will switch on show the Sony logo then the Android logo and then switches off, and then blinks red 6 times.

    I've read that this is the backlight, and during it showing the initial logos I can see that the left side is definitely darker.

    I've also read that you can bypass the error to get it working but I'd prefer to fix it if at all possible. Any help would be appreciated.

    Many Thanks in advance.
