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 ?


Hi
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

Sony Wega T.V. won't stay on.


Over Voltage Protection 03. Three blinks of standby light denotes this. The fault is with its main power regulator section circuit. If you wish to get more details about these blinking codes, check this link. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.

Screen turns off and on, stand by light flashes


How many times do the standby light blinks at once time of switch ON. Count these numbers carefully for at least 3 times power ONs. These are fault indications. From these counts, you can detect the location of the faulty stage inside the TV circuit. Check this link for more details about blinking codes to Sony TVs. All details are there.

Hi,
3 times red light flashing indicates that lamp cover has not been fixed correctly in tv after lamp replacement. Please make sure lamp cover is fixed securely after lamp replacement.
Thanks.

I try to turn it on but it just blinks on stand by


Probable Lamp. If lamp hasn't bown the red Lamp Lite won't flash but other lamp issues cause stby timer light to continue flashing. If stby red lite is flashing, count the no. of times flashing - could open thermal fuse (6X flashing)

THE POWER STAND BY LIGHT IS FLASHING RED 4 TIMES


Anything less than 5 blinks is major trouble. More likely vertical IC and circuit failure. Picture has been muted or turned off by TV. If Stand By light was blinking 5 times the Stand By might have came out self-diagnosis function or mode.
Contact Sony Service Tech for service adjustment to fix problem.

If standby light flash 3 times that means Lamp Cover is open or not fixed properly on its place.
