SOURCE: can not power it on, the power LED keeps blinking.

Most likely, the power board was defective. You need to replace it.

SOURCE: power & OPC lights keep

That signal the fact that the power source is in protected mode - a component has failed in the tv and now acts as a short. When the power source tries to start the failed component starts to draw so much power that the voltage drops; this trigger the protection system of the source that shuts it down to save it from frying.
To fix the tv you will need to open the tv and test the voltages on the output rails of the power source to find out which one is triggering the shut down. Then just follow it to the failed part. This requires a good electronics experience.
In your tv the most usual part to fail is the sound board: the radiator on the audio amplifier is undersized so the amplifier overheats and fries. The sound board will have to be replaced - a $250 job at a repair shop.

I have a Samsung LN52A550P3FXZA. The TV does not come on.

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.
If blinks continue without any pause, the main board is faulty.

Menu keep on blinking

Disconnect the monitor from the computer. Then turn on the monitor, if the menu keeps on blinking then that means the screen is starting to go bad and the monitor needs to be replaced.
You can also hook up the monitor to another computer. If the blinking stops then that means its an issue with the video card in your original computer.

I have Samsung HL-S5087W for about 5 years and it is turning off by itself-any suggestions?

i hope your TV is getting ''off '' by itself when you are trying to turn ''on'' - not when you are watching TV...........then following is the situation ..........IF LED IS BLINKING then---- usually after 4 or 5 yrs EHT ( transformer that supplies voltage to tube ) becomes weak - then TV won't get ON.. means no picture no sound ..but LED blinks - in some TVs along with EHT 1 or 2 components like resistor, transistors, etc will also gets deffective ..........IF LED IS ALSO OFF then on main board in power section area some component is deffective ... MAIN BOARD SHOULD BE CHECKED COMPLETELY........ so solution is TV circuit board has to be checked to find whether only EHT is deffective or other components are also deffective - price of EHT will be between Rs.250 (US$ 5) to Rs.600 ( US$ 12) ........iam from bangalore.....i don't have any idea about EHT component's price & service charge in your area........this problem cannot be solved by user unless user is a technical person having idea about components (resistors, transistors,diodes,...etc..), having multimeter , soldering iron & other my suggestion call TV service engineer or contact samsung service centre.........
