Question about Sony XL-2100U Projector Lamp for KF-42WE610, KF-50WE610, KF-60WE610, KDF-60XBR950, KDF-70XBR95

1 Answer

Sony KF-60WE610 Hello, I have a 4 year old sony WEGA tv. The screen went black a couple days ago and the Lamp light came on. I order the Sony XL 2100U lamp (per the TV instructions). I pulled the old lamp out and it was blown (shatter in the lamp and there was black residue around the lamp plug). So I follow the instructions and the TV will not come back on. I even do not get the LED to blink appropriately to tell me if the lamp door is on correctly or not. Please help

    Note: The LED is supposed to be blinking once I replace the lamp door (1 once if I got it correct, 3 times if incorrect, 4 times a problem). Anyhoo, no blinking. Help.

    Where would I get the past number for the IC? Also what is an IC (I assume it IC stands for something)? Not a techy person so if you could tell me where to look that would be great.

  • ttaris Feb 23, 2008

    Since the repair man cannot come out till next week maybe you could walk me through this. I am and engineer with Circuit experience so but have not worked on Circuits for 10 years. What would be great is to tell me what am I looking for when it comes to a power supply block. I pulled off the back of the TV(note pulled the plug so I do not hurt myself. There are alot of things that have part numbers on them, would the PS block be were the electrical coord runs into the TV or where the lamp is or approximately is. Thanks

  • ttaris Feb 23, 2008

    Thanks there is a smaller board the cord runs into. Then from that board, there is a much bigger board that looks like it is connected to the first one.

    Note: I wanted to make you aware that the LED does come on in the front of the TV, so I did not want to mislead you that there was no power, just the signals to determine the door is on or off do not blink. The LED is normally red when powered off. When I try to turn on the TV, the LED blinks green for a while, then the Lamp light under the POWER LED turns Red. So my orginal though was the lamp door diagnostics were some how broked since there is power still running to the TV. But could this still be the power supply?

  • ttaris Feb 24, 2008

    OK. I actually has the lamp door off and got 3 blinks which the book said was the diagnostic for the door. Put the door back on and got a solid red light.

    Press the power button on the remote and a green light blinked 46 times. At blink 3, 22, and 41 there is a noise link something trying to run (ie. Hardrive starting). On the 46th time the Lamp light blinked red at the same time as the last green light blinks.

    The lamp light blinks for anywhere from 120 - 123 blinks until the Power LED light goes back to a solid red light.

    So when you say the cooling fan is not "user serviceable" I assume you mean that this means I cannot fix it and need a repair man.

    Assuming this, what would one expect as a reasonable cost to fix the TV (if this is the issue)?

Some of the ICs on the power supply block are damaged. This can possibly due to high voltage or defective IC. What you can do now is to get a new PS block. If you can get me the part number i can help you find it..

    IC stands for an integrated circuit chip.. But since you have admitted that you are not techy i strongly advice that you take the assistance of a tech to get it fixed.. The repairs should run you about 100-150$ but thats better than damaging the set anyways.. PS:IF you still want to fix it your self then let me know and i will help you fix it.

    It is a ciruit board to which your power cord goes. Before that check for any broken fuses, wires and any indications of burnt areas on the circuit board.. You may also check with a multimeter to check for broken circuits.. If you can get me the readings i can analyze them for you..

    Ok... this info is crucial.. Can you tell me how many times the LED blinks before turning red?Please be careful as this count is essential for proper diagnosis of the problem.

    The red LED for the the lamp may flash which CAN indicate that the
    cooling fan is not operating. This fan is typically very quiet and has
    failed on MANY units. It is behind the bulb at the very back of the TV
    and is not "user serviceable". My repair guy says this is common and
    you can at least observe the fan through the rear grill and if it is
    NOT turning, then it IS failing.

    50-75$ maximum is the repair cost. I repair tv sets myself but i gotta say this is one thing i am still scared of.You may try it but you might seriously damage the tv and is very risky . After all your tv is worth a lot more than 50$.

    60 " SONY KF60WE610 screen went greenish


    Depending on when you bought this TV, this could be the lamp. Does the red light below the green light come on? (That's the lamp light). This light typically comes on around the 3rd year of use for an average individual. I've recently enountered the same problem and will try to replace the lamp myself. Apparently its very simple.
