Question about Sony Televison & Video

1 Answer

Last Sunday Welcomejee tried to help me diagnose and fix a problem with my Sony KP-53XBR45 rear projection set. He was very helpful and suggeted replacing two ICS on the ''D'' board. I have done that but the problem remains. When the set is turned on I get sound but only 4 to8 seconds of thin horizontal lines in the center of the screen then the screen goes blank. I still need help to fix this. I get 14v +/- at the fuses on the ''D'' board. Problem originated when the antenna connector was broken. That has since been replaced with a new component from Sony

    Hi again. Thanks for responding. I checked voltage at both resistors and have 14v DC +/- at each. Am I to assume that is within tolerances given I am using a multi-meter? If so what next to check? If I have your permission I can take a short video of how the set reacts when turned on, ( brief horizontal lines for 4 -8 seconds then blank) and send it to you so you can see what I see . I believe I still have your email address from when we started this.

    Please let me know and thank you very much for your time and expertiese.

    LuiTutin.

Hi again,
You said TV shows thin horizontal lines in the center of screen for 4 to 8 seconds then screen goes blank.
That shows vertical deflection IC1501 is not working, IC1501 is also located on D board as shown in below image.
Check its +/- 15V supplies that are coming through 2.2 ohms resistors, marked as well.
Thanks.

    Hi,
    I got your video clip and watched tv problem.
    This is vertical drive section problem. I'm still looking into schematics to suggest you what to check.

Hi,
Replace convergence out ICs to get it fixed.
You can replace these chips if you can replace parts in circuit board with proper tools or ask local tv tech.

Stand by on my sony kp-53xbr tv is blinking steady


That can be caused by lots of different things going wrong. You will not be able to repair that yourself, and will need to have a technician look at that kind of a problem.
