    Re: Sony KDL-40V3000. 5 blinks error code

    Hi Budm,

    The TV is now working after replacing the tcon board!
    Thank you very much for your help!
    Next time in repairing, I would do the ff: ask help from this site, board level checking, and not to use strand of wire replacement for the fuse
    It could saved me cost and time if I detected that bad MLCC SMD cap on the tcon board.

    Also thanks to glitcher, badcaps admin, and shopjimmy.

    you can find the schematic in the service manual except for the tcon. I am not an expert in troubleshooting LCD TV, I am also asking help here, My tv (same model) is also for repair and experts of this site is helping me.

    thanks Budm, I sent an email (still waiting for reply) and I also check the SJ link you provided, and it is 1837H. Thanks a lot. I will check also the LCD panel sticker numbers, and hopefully I could found it here in the Philippines.

    Re: Sony KDL-40V3000. 5 blinks error code

    Thank you Budm.

    Anyone could help me....?
    I will go to electronic parts shop tomorrow and please help how could I know if the new tcon is compatible in my LCD panel?

    TCON board number = 4046HSC4LV3.3
    TCON lot number = J1837H8A062W 007880
    TV was bought in Canada and it is made in Mexico.

    Should I look for exact part number? how about lot number? it should be 1837? other characters in lot number could be different?
    Please help.

    Thank you.

    Re: Sony KDL-40V3000. 5 blinks error code

    Hi Budm,
    The cap is still ok physically.
    When I desoldered this cap, I found burnt pad (underneath this cap). Please see picture.
    You are correct, multiple pins cable for this line with a component (B2) in series with Cap pad 1. Cap pad 2 is gnd.
    1. I checked this Cap (unmounted) it is not shorted (maybe shorted before it smoked).
    2. I checked also resistance across the Caps (for left and right ribbon cables), they both in 20~30 ohms (I am using analog meter) with and without ribbon cable.
    3. I am...

    Re: Sony KDL-40V3000. 5 blinks error code


    Thank you Budm.
    I remember, when it smoked, the pad near an SMD cap burnt (the pad is still ok when I cleaned it, so I think the smoke came from this pad).
    Please see encircled pad near the cap on the attached photo.

    I will check if this cap causes the short circuit.
    And as you suggest, I will check also the board inside the panel.
    If tcon part causes the short ckt, it gives me hope and I will order new tcon.
    Thanks....

    Re: Sony KDL-40V3000. 5 blinks error code

    I have a question, if the Panel have short circuits, why the tcon board smoked? why not the ribbon cables? Ribbon cables have higher current capability than the components on the tcon board?

    Thank you Budm.
    So this means, buying new TCON is not advisable anymore if Panel have short circuits.
    It will just blown the fuse of the TCON again.
    And the Panel short ckt is not repairable.

    This TV was shipped from other country, and it is working before the shipment.
    Maybe this is the cause of the Panel short ckt, improper handling.

    Thank you Glitcher, Budm, and Badcaps Admin for helping.

    Hi Glitcher,
    I have no fuse part, so I used again a strand of wire.
    I tried to short the fuse using a strand of wire.
    Removed ribbon cable that connects to the panel.
    Turned ON tv, no smoke, no Error blinks, power LED in Green, backlight lamp is ON, no picture.
    Turned OFF tv, put the ribbon cables.
    Turned ON tv, no smoke, no Error blinks, power LED in Green, backlight lamp is ON, no picture.
    I put antenna.

    Reply from Glitcher:

    Remove the ribbon cables that connect to the panel. Replace the fuse and see if itll blow when its not connected to the panel.

    If it still blows then its probably a bad tcon board. If not then the panel is shorting it.
