1. I would first try to find out if everything is properly plugged in place inside your pc. make sure everything is properly seated

note: BEFORE you get your pretty hands inside the case make sure you ground yourself by touching the power supply before teaching any other components, failure to do this you're risking to damage other componets like memory, or the motherboard.

2. if you did 1 but still the system would not power up, you're problem is likely to be your power supply dying on you. I would suggest to replace your power supply and test.


also check this documentation on troubleshooting power supply issues:

hope it helps.. and post back with your findings.

Then if it doesnt power up hold the menu and the Device/input buttons on the set both in together for 5 seconds the light will blink a series of blinks pause briefly then blink another number of blinks then pause then it will repeat the same two digit blink sequence a few times . Let me know the two digit blink sequence.

The red light is blinking and when i turn it on it goes to green for a few seconds and then beeps and blinks red again.


You have "The red ring of death" If 1 corner is blinking: Turn it of and wait a few days for it to cool off. If 2 corners are blinking: Do the same, but check after 3-5 days to see if it works. If 3 corners are blinking: You HAVE to see a xbox repairer, because you can't wait after 3 rings. Saddly, a complete ring of red: You can't do anything about it, it can't be repaired, but check the power wire and reattach it, there's a little glitch where if you loosen the wire, it does that. Good luck!

I have a 4 year old Sony KDF-E42A10 television - the power/standby light blinks red 5 times, pauses, blinks red 5 times again, etc. I have replaced the lamp previously when the light was blinking red 3...


Hi there,
5 blinks means there is a problem with the video board. It could be as simple as unplugging everything, includding power. Wait 3 minutes then plug power only back in. Or it may be a damaged component that requires replacing.
Hope this helps

How can I fix my PS3 for free? It won't power on completely and the red light just blinks


If ur ps3 console wont start up....then the things to check are>>> 1.check ur power cable 2.check whether u have inserted the disc properly and precisely. 3.check the insertion of memory card... 4.check the video port.......
checking your console and making sure those fans are not blocked off. If you notice a lot of dust on the console, clean it off right away. Once you fix the blinking red light of your ps3 and your console is working again, you will want to keep the vents clean......

find the hard drive on the side of your console and remove it. Wait a few seconds and replace it. In some cases this may fix PS3 red light. If you still see the blinking red light, there is a chance you have more substantial damage inside your unit.

Power problem


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.

Playstation 3 at power on, light becomes white then blinks red


Probably and overheating problem. Here's what I suggest:

Try using some compressed air and cleaning the vents out below. If that doesn't work then you'll have to remove and replace the thermal compound on the GPU and CPU.

You might also consider a System Restore if you can do it before it shuts off.
