The casing is pretty easy to take off
with a phillips screwdriver or there may be a latch to get the case off

all cmos batterys are pushed in holders
you can get these batterys very cheap at many stores, look close at it for the number
example maxell cr-112

For sets that have no video do the following.
  1. Turn your TV on
  2. Using the original Philips TV remote press the following keys. Press each key for 1 sec then press the next.
  3. From the remote press 0 6 2 5 9 6 MENU
  4. Wait a few seconds. The red power light should begin to blink.
  5. The blinking sequence will determine the error code.
  6. You will have one long 5 second red blink followed by the error code.
Note: On some sets the TV will automaticaly blink the error code when its powered up without having to go into the SDM menu. If you power light blinks after the set is powered up jot down the sequence.
Example Error Codes from the power light.
( RED 5 Seconds ) off ( RED 1/2 Sec ) off ( RED 1/2 Sec ) off ( RED 1/2 Sec ) = Error Code 3
Example #2
( RED 5 Seconds ) off ( RED 1 Sec ) off ( RED 1/2 Sec ) off ( RED 1/2 Sec ) = Error Code 12

Blinking red light


When someone say that his/her Xbox is having Blinking red light problem, It means it needs to be repaired. If you are using Cooler than it is not a cure but a prevention. You could have used cooler before acutally having the problem just to prevent your Xbox. But now you will have to either get it repaired from Microsoft (in case your Xbox's warranty is not expired, but one thing to note is that you will have to wait for at least 3-4 weeks to get back your Xbox) or you can Fix your Xbox's blinking red lights problem yourself with the help of DIY Video guide available on Internet. You can fix yourself without any technical knowledge.

HP Compaq d530


it all depends on the number of flashes , pause, repeat.
Since the problem did not indicate any beeps her is the following info


Power LED blinks RED 2 times, one every second, followed by a
2-second pause. = Processor Thermal Protection Activated


3 blinks 1 second apart = Processor not installed (not an indicator for a bad processor).

4 blinks 1 second apart .= Power Failure (power supply is overloaded)

Other possibilities are:
5 blinks 1 second apart No memory
6 blinks 1 second apart No graphics
7 blinks 1 second apart System board failure (detected prior to video)
8 blinks 1 second apart Invalid ROM
