Question about Sony KP-46WT520 46" Rear Projection HDTV-Ready Television

10 flashing lights then 9

My Sony KP-46WT520 began not turning on and the standby light would flash 9 times, pause, 9 times....etc.. It would still turn on eventually but today it wouldn't turn on again and now it is flashing 10 times first then it goes to 9 flashes, pause 9 flashes, etc....
I am thinking of replacing the G-board but not sure. Someone had mentioned just replacing D6116 or D6301 on the G board. What do you recommend?

Thanks for any advice you may have :)

    The TV won't come on at all. I am thinking I need to replace the entire G-board but Sony said they no long sell them....lol :) Crazy because the TV is only 3 years old!

    I've got the same problem. 10 flashes, then 9,9,9,9,... Granted the tv isn't new, but it isn't that old. What's the fix to this problem and the costs associated with it ?

    I've found out that if I completely shut my DirectTV box off, the tv comes on. If the Direct TV box is on, I get the 10 flashes and then the 9,9,9. This problem just started after I installed a new Direct TV box. Anybody heard of this or dealt with it ?

You need to see if you can get tv on in service mode.
if it will only work in service mode then yes replace those 2 diodes

Sony kp-51ws520 when turned on just has standby light flashing . the rest is all dead, no picture or voice.


Standby flashing light shows that tv got some internal problem. How many times standby light is flashing is info that provide info about what section of tv got problem.
Count standby light blinks and let me know, there would be 3 seconds long pause in blinks so count pause to pause.

Sony kp-46wt520 standby light flashes 10 times. Does not power up.


hello 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.

Sony kp-46wt520 rear projection tv: standby light flashes


Two things here.

1) This is a CRT based set so there is no "lamp" involved.
2) The standby light should be blinking a repeated count of blinks with a 2 second pause between counts. Please report the exact count here. This will indicate the circiut in which a problem was detected.

With the above information, we can provide you with a more detailed description of the problem as well as the likely solutions and cost.

Thanks,
Dan
