SOURCE: I have replaced the power supply on my Acer Aspire

When you have this problem on this PC, do not replace the power supply or the motherboard until you have first tried pulling out the video card. When the video card fails it can cause the x1700 to not power up. Pull the video card and see if it will power up without it.

I have a Sony KDF-E50A10 and I replaced the lamp. But the stand by/power light blinks red 3 times and still no pic or volume or nothing. What could it be ?

I managed to locate a manual for your TV and also a Support page on the Sony website which identified your problem clearly on two entries ie "The STAND BY indicator on the front of the projection television flashes three times" and "The STAND BY indicator on the projection television flashes 3 times". I thought this was going to be easy having found these, but both led to a page that said "This solution is no longer available". Thank you Sony !!!!
I didn't give up here found a YouTube video which described your "3 flashes" and stated that the bulb needed replacement if this was seen. I understand that the model is not exactly as yours but I give the link below:
How to replace TV lamp
Please look at it carefully because it looks as if - if this is correct - that you may have replaced one faulty bulb with another faulty bulb. Other than this I can't find anything very helpful on the internet.
Good Luck and best wishes

Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206. For more information go to

I have a Sony KP-51ws520. I cannot power on. says stand bye and blinks 9 times.PLEASE HELP it is only 5 years old and they says some of the parts are no longer available.

Those LED flashs are a fault indicator...First thing to do is to try a reset:

With the TV plugged in push and hold down the reset button on your remote then press the power button on the the TV and then release the reset button once the screen has come up.

9 blinks means, "Zero Crossing Detector" and the probable cause locations listed are "D6166 or D6114 is open

If you are handy you can replace D6301 diode and it fixed the problem. You can buy that diode at for $3. good luck

If still no luck then this is going to require a serviceman.

2004 Sony 52" Wega dont turn onnthe stand by light stays flashing. This TV first started by taking long to turn on and now and then would turn off until one day it just didnt turn on and the standby button...

When that model Sony shuts down the LED starts blinking as you say but it is telling you something because it blinks a certain number of times and then pauses and repeats the number of blinks. Count the number and then I might be able to help you narrow down where the trouble is.

The standby light should be flashing in a repeated count with a short pause between the counts. If you could post that count here, it will give us an indication of the circuit in which a problem was found and allow us to provide solutions.
