Robably itz either minor case of software corruption/improper ground/cpu fan..
or major case of faulty or defective main board/ram/daughter or addon card(s)..

..plz do check the following as in order:..
the Hardware part:..
1)a)in power on mode, open/unplug the data/vga cable of the monitor from cabinet..see if raster or 'osd' is appearing on the monitor screen..if so monitor is ok..else replace the monitor and see..[not applicable in case of laptop]..
b) in case of laptop try to get output from external display unit/monitor using vga port..if there's proper display in there..the problem is probably with either the 'lcd' or 'ccfl' or 'inverter circuit'..

2) if u hv a graphics card, replace with a standby or onboard and see..[not applicable in case of laptop]..

3) unplug mains supply..pick open/remove the cmos battery..check (above +3v)..resit..

4)see if the ram(s) is loose/faulty..open clean/remove carbon & or oxide formed on the teeth with an eraser n resit it..or replace with a standby n see..

5) a) see if ur hdd is noisy or emitting any 'ticking' noise (like 'tuk tuk' or 'kirr kirr')..
b) or if the system is not supporting either the newly installed device or itz software/driver /firmware
if so, u need either a fresh os installation or ur hdd is likely to b replaced..

6)remove/clean dust neatly..dust is non-uniform in nature n may cause jam/short circuitry/excess resistance n many more..resulting an increase in heat..

7) open the CPU Heat-Sink with fan out of the socket..put some "Heat Sink Compound" (available in local electronics chip level spare market) between the cpu/processor and the CPU Heat Sink *** fan..resit/fit it tightly in position..

8)on main/mother board..see with a debug card for mb error..may b short..look for defective capacitors(esp above1000mfd)/mosfets..go through the mb's south bridge n the circuit lie around atx connector..the crystal clock generator (if cpu isn't heating up)..

9) [in case of desktop] the smps itself may b defective/faulty..check the outputs of smps viz. 0v (black~ground); +12v (yellow); +5v (red, green~ps-on, violet~pg& grey~sb); -12v (blue); -5v(white); +3.3v(orange)..the 'oscillator and error amplifier ic', or pwm switching regulator circuit..look for defective protector-transformer/resistance (esp 4.7k)/mosfet..
check the battery n adapter [main power], in case of laptops..

the Software part:..
1)hv a licensed and UPDATED antivirus installed (i prefer avg/kaspersky, remember, without updation a full version antivirus is useless)..

2) download, install n run microsoft kb890830..http://www.microsoft.com/downloads/details.aspx?FamilyId=AD724AE0-E72D-4F54-9AB3-75B8EB148356&displaylang=en..

3) download n run Startup Control Panel..http://download.cnet.com/Startup-Control-Panel/3000-2094_4-10039330.html..'remove all the unnecessary startup items from here..(if u can't find what to remove, post me/us in ur comment with all the items listed in each n every tabs herein)..

4) remove all unnecessary software from add/remove programs..

5) download, install n run 'Advanced System Care Pro'..http://download.cnet.com/Advanced-SystemCare-Pro/3000-2086_4-10399324.html..

6)disable the following:..
a)'Automatically Restart' right click on my computer->properties->advanced->startup n recovery->(un check on the) Automatically Restart;
b)'Error Reporting' right click on my computer->properties->advanced->error reporting->disable error reporting->(uncheck on the) 'but notify me when critical error occur'..

7) Increase the size of Virtual Memory, Initial: 1440; Maximum: 2880

if u r not a professional, always better to seek advise from ur system admin/vendor....

I bought a Sony BDV-E570 in US and it came locked for region 1. As I live in Brazil, I need to run region 4 dvds. Do you know how to unlock it? Thanks


NO LIABILITY IS OFFERED HERE!! THIS IS A HACK!!!


Full procedure for a oneforall remote is as follows:

1. Press DVD
2. Hold the magic button until the DVD button flashes twice.
3. Press 0533

4. Hold the magic button until it flashes twice.
5. Press 994
6. Press Magic Key (don't hold)
7. Press 00189 (if your oneforall remote uses 4 digit or 3 digit codes, use less leading zeros)
8. Press 1 ( this sets it to key 1 - it flashes twice )

9. Hold the magic button until it flashes twice.
10. Press 994
11. Press Magic Key (don't hold)
12. Press 00255
13. Press 2 ( this sets it to key 2 - it flashes twice )

14. Hold the magic button until it flashes twice.
15. Press 994
16. Press Magic Key (don't hold)
17. Press 00095
18. Press 3 ( this sets it to key 3 - it flashes twice )

19. Hold the magic button until it flashes twice.
20. Press 994
21. Press Magic Key (don't hold)
22. Press 00221
23. Press 4 ( this sets it to key 4 - it flashes twice )

24. Hold the magic button until it flashes twice.
25. Press 994
26. Press Magic Key (don't hold)
27. Press 00079
28. Press 5 ( this sets it to key 5 - it flashes twice )

The remote is now programmed and ready to use, to make the BDV-E370 region free:

1. Use the remote that came with the player to bring the player out of standby, make sure there isn't a disc in it.
2. Press 1, 2, 3, 4, 5 on the oneforall remote. The 24p light will start flashing. (Centre light)
3. Put the player back into standby with the Sony remote.
4. Hard reboot machine (remove power)to prevent the 24p light flashing indefinitely.
5. Next time you turn on the player it will be region free for DVD playback.

This worked for me, but obviously I accept no liability for anyone who tries it on their machine.

PS3 won't turn on


hi Torgsrus.
PS3 Light sequence
The following pictures illustrate the CECHX0X model, however the light sequence is applicable to all PlayStation 3 models.

No lights are on:

When no lights are on, this means that the main power switch on the back of the ps3 is off or the PS3 is unplugged. When the main power switch is off (the '0' is pressed) and you will not be able to access any features of the PS3 system. To turn on the PS3 system, make sure the main power switch is on (the 'I' side is pressed down).

If the PS3 does not turn on:
· Make sure the power cord is not frayed or damaged
· Try using another power cord, if available
· Make sure the main power switch on the back of the PS3 system is turned on
· If you continue to have issues contact our Technical support.

Solid Red:


When the power status light is solid red, this means that the PS3 system is off (or in standby mode).
Standby, mode means the PlayStation 3 system is off, but is ready to be turned on by pressing the power button.

If the ps3 system will not turn on when you press the power button, this is an issue with the PS3 system and you will need to send your system in for service.

Solid Green:

When the power status light is solid green, this means that the PS3 is turned on.
You should be able to navigate the XMB, play games, access the Playstation store,etc.
To turn of the PS3, simply press and hold the power button for two or more seconds.
If the power status light is green ,and you are experiencing problems- have a look on our forums for troubleshooting.

Flashing Red:


When the power status light flashes red after using the PS3 system for 3 or more minutes and shuts off, the PS3 system has possibly overheated.

This may be caused by poor ventilation or the vents may be blocked.
If this happens:
· Check to see if the vents are blocked. If the vents are dusty, vacuum the vents to remove the dust.
· If the PS3 system is in an enclosed area like an entertainment area, move it to a more open area.
· Leave the ps3 system off for 30 minutes to let it cool down.
· If you continue to have issue, you may need to send the console in for service.

Flashing Green:


When the power status light flashed green, it means that the PS3 system is turning off. Please wait while the system turns off.

If the PS3 system does not shut down immediately, it may be trying to finish save data to the Hard Drive. If it is, do not turn the main power switch on the back off as it may cause data on your hard drive to be corrupted.

If the green light continues to flash green, the ps3 system maybe trying to write to the hard drive, shutting down or running programs. It may take longer to shut down depending on when you pressed the power button. If the green power light flashed for a very long time, you can try holding the power button down for 5 seconds, the console will beep and should turn off. Then try to restart the PS3 system.
Flashing Green, Yellow and Red:


When the power status light goes from green, to yellow, to green, then to a flashing red, this means that they may be an issue with an internal part with in the PS3 system. This may be caused by a variety of reasons and would need to be diagnosed by our support line.

When the PS3 power light flashes in this order, you can contact our Support Line for further assistance.

Solid Blue:

When the disk status light is remaining a solid blue, it means the disc is inside the PS3 system. If you wish to eject the disc, hold down the eject button for 2 seconds and the blue disc status light will flash indicating the PS3 system is attempting to eject the disc . (NB: the power indicator light will always be a solid green).

If the disc is inserted into the ps3 system, but does not show up on the xmb or will not play, this may indicate an issue with the reader- check our guide Discs are not loading in my PlayStation 3? for further troubleshooting.

Flashing Blue:


When the disc status light is flashing blue, it means a disc was just inserted into the ps3 system or a disc is trying to eject from the ps3 system. Depending on when you pressed the eject button, it may take longer for the disc to eject. (NB: the power light will always be a solid green)
If the light constantly flashes blue, it may be an issue with the disk being stuck in the system. If this happens there is no way to remove the disc yourself if you are using an orginal 60GB PlayStation.

Power button failure


  • Power Light Shuts Off
    If the power shuts off during game play (even as much as 30 minutes after the system is turned on), then turns off and won't turn back on or the fan isn't working, the system needs repair.
  • Power Light Flashes
    If the power light flashes once when power button is pressed, then turns off and won't turn back on, the system needs repair
