Laptop does not turn on when when power button pushed on and led light blink 3 times

Hello,
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
Good Luck!

5 times LED blinks in Panasonic PT-47WX42 shows problem with convergence out chips failure as this tv has two big black ICs STK392-110 as convergence output, replace them to fix tv problem.

Yes! judging by all the cascade break downs, I would suggest replacing the motherboard, HP has a history with motherboard issues.

In standby mode (red led on/after the led stops from blinking), press "Display", "5", Volume (-)", "Power on" on the remote control in sequence, self diagnostic screen will be display, let me know the what is on the screen to diagnose where the fault came from.

There are 4 ways to program your remote:
-Brand Code search and entry
-Direct code entry
-Manual Code search and entry
-Auto Code search and entry
*ON TV/VCR(DVD) combos you must program each button individually and that button(ie. TV or VCR/DVD) will program that part of your device.
*the DVD/VCR button programs DVD by default, in order to program it for VCR you must put it into VCR mode:
1.hold down the DVD-VCR button-->the red led will stay lit.
2.while holding down the DVD-VCR button press the number 2 --> the red led will turn off
3.Release the DVD-VCR button--> the red led blinks 4 times and turns off
4.The DVD-VCR button is now set to VCR mode-->program for VCR

BRAND CODE SEARCH ENTRY:
1. turn on device
2. locate brand codes(sorry, I don't have it, try finding genaric RCA codes)
3. hold down the component button--> led should stay on
4. while holding component button, also hold power button--> the led will turn off, then after 3 seconds it will turn back on.
5. release both buttons--> led will stay on
6. enter brand code--> led blinks once
7. press power button repeatedly until component turns off-->each time you press the power key the remote sends a different code for that brand. led blinks once
8. if power on your device turns off press the stop button to save configuration-> led turns off
9. if the led blinks 4 times and turns off, you have reached the end of the codes for that brand, try using a different method to program your device.

DIRECT CODE ENTRY:
1. turn on the device
2. locate your device codes
3. hold component key down-->led lights up and stays lit
4. enter code while holding components key--> as first key is pressed the led turn off, then as 4th digit of key is pressed the led turns back on
5. release component key-->led turns off, try using your remote, if it doesn't have all of the functions you need, try a different code
6. if the led blinks 4 times after entering code you have entered an invalid code, try again.

MANUAL SEARCH AND ENTRY:
1. turn on device
2. hold the component button--> led lights up and stays lit
3. while holding component button hold power button-> led turns off then turns back on after 3 seconds
4. release both buttons--> led stays lit
5. push the power button a bunch of times until the device shuts off-> each time the power button is pressed a different code is sent to the device, the led blinks each time.
6. if the device turns off press the stop button to save your config.
7. if the led blinks 4 times you have reached the end of the code list, there are hundreds of codes, you may be pressing the power button for a while...

AUTO CODE SEARCH AND ENTRY:
1. repeat steps 1-4 of "manual search and entry"
2. press the "play" button--> led blinks 10 times, sending a code each time
3. continue pressing the play button until the device turns off
4. if the device turns off press the reverse key to until it turns back on then press the stop key to save config.
5. if the led blinks 4 times you have run out of codes, try a different method.
Now if someone would please post the codes, or if someone knows the code for a durabrand DVD-1002...
