Question about Sony KP-53S35 53" Rear Projection Television

1 Answer

Wont turn on

The red light on the front just flashes slowly. Under the red light it says sleep/stand by we had a storm last week and seems to me that the power came back pretty strong and now there is no image but you can see the red light in front with a non stop blinking.

    Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and
    VDR601 (should show open).
    Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground,
    or held high), IK video path is defective.
    One blink - not used for the self-diagnosis
    Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a
    short in the power supply of any of the circuits.
    Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is
    also a problem in the power supply circuit, check T603 and R672.
    Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.
    Check IC1509, Q1505
    Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the
    self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on
    the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen
    slightly.
    Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 &
    516 and the jungle IC, IC206.
    Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety
    shutdown. Check power supply regulation and horizontal circuits.
    Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406
    audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback
    transformer), or the associative components in the high voltage circuits are defective on the D board.
    Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or
    Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times
    you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -
    12 or -13 (negitive).
    Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors
    are bad, check R8051 and IC8005, also on the "D" board
    those are what the blinks mean for a sony tv.
    Keep me posted.

Sony KP53HS30 Stuck in Sleep Stand by


I don't believe it is stuck in the sleep standby mode, rather it has shutdown with an error. Is there a pattern to the flashing? Does it flash a set number of times?

Ilo 32 lcd


I have the same issue. Here's a temporary solution, which is what I've been doing for the last couple of weeks, unplug the unit from the wall, just long enough for the red standby light to go out, then plug the unit back up. as soon that the red standby light comes on, press the on button the the remote or the unit. You may have to do this couple of time before it works. Somedays it works on the first try for me and then somedays I have to do it 3 to 4 time. I sure that at some point this will stop working too.
