Re: power light blinks
I would start with C869 a 2.2 Uf at 200 Vdc in the power supply. I have replaced a fair share of those in these sets. Of course the first thing to check would be the pico fuse in the power supply regulation circuits F860 a 4 Amp Pico Fuse and if it is blown, you will have to replace Q801 the Regulator IC Str-Z4214 Part # 23906369. If you're not that good at soldering and measuring capacitance and resistance, this would be a job for a more experienced tech.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/ http://electro-medical.blogspot.com/
Blinking codes details of many popular brand TVs are given. Surf the site with patience.
Do you have a battery backup/surge protector?? Take it out of the loop and plug directly into the wall.
If the power light is blinking amber - The computer is receiving electrical power, but an internal power problem might exist. Ensure that the voltage selection switch is set to match the AC power at your location (if applicable). Ensure that the processor power cable is securely connected to the system board
Hope this information will help.
Your response is very much appreciated. Thank you for using Fixya...
Wireless keyboards and mice have a "sync" button you can push to make sure that the peripherals and the receiving station are all on the same channel. On your receiver (the one you plug into the computer) you will see a button. Pressing this should cause the lights on it to blink. When this happens press the button located on the bottom of the mouse (usually very small and recessed - try using a pen tip). The lights should stop flashing and the mouse will be on the correct channel and should work. Repeat the process with the keyboard if that does not work as well.
