From what it seems in your question... the problem has already went away... However, I actually know about this. There is a fuse inside the tv near the power button called B-3a... If you replace that fuse it should help fix permanently

Authorized sony repair center told me the problem was the Q Box. Ever heard of this? Part runs about 300 bucks. TV is out of warrenty as it is 2 years old. Do you think it is worth it to fight sony and get them to replace the part or just fix the TV?

Part Number is A1167541A, service rep called it a Q Box in the diag, however the web says its the b block assmy.

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.

I have a sony wega KDF-E50A10 and wanted to know what does it mean when i get 4 red flashes followed by a pause and it just keeps repeating over and over. this happens when i try to tun on my tv and after...


It is an indication that you have a faulty power supply most likely the leaky electrolytic capacitor on the main board but not all the time, lot of parts are going to consider to isolate the defective parts.It is not DIY and quite technical.

If your unit is under warranty then avail it from the manufacturer, they will fix it for free and/or little charge only.

If your warranty is already void then I've advice you to send it to a qualified service center/repair shop to isolate the faulty parts.

Please rate my help.
