I had exactly the same problem When the TV was switched on all I could see was a flashing green light. After cheching the TV internals and not seeing a problem including the power supply unit which looked and checked normal. Here is what I did to get M TV working again.
Disconnect it from the power supply. Hold down all the buttons simultaneously i.e. the on/off, the volume, the programme, menu buttons, all of them simultaneously and Plug it into the power supply again.
Lo and behold My TV jumped back into life after an absence of about 4 weeks.
Try it yourself exactly as above.

Best of luck.

Hi


Thanks for using FixYa. If the TV isn't turning itself on then the fault protection circuit has detected a fault and has turned down the TV. The blinking indicates a fault. You'll need to check various things to find an answer which part is bad. Please check these---

1. Check for signal cables at the back and also try unplugging the TV for 8-10 hours to reset it.

2. Swollen /bulged capacitors on the power supply board-- This happens due to overheating of capacitors.

3. If the capacitors are fine then you'll need to check for connectors on all the boards and also the fans if they are working fine.

4. Make sure the lamp connections are fine and ballast is not burnt.

Note-- Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition, so please be careful.

Try to reset the TV by unplugging it for 6-8 hours.

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Rylee

My power comes on, then the green LED light switches to red, and flashes 6 times over and over. I tried the fix on youtube with the IC capacitors for the 50PF9731D/37 even ordered the $1 capacitors but...


I am definitely a girl explaining this because I don't know the correct parts of the tv. Here goes. We had the same problem last year, called philips they advised I do a software update on the tv because that fixes everything....wrong. The light still flashed and no picture. I called them back and they said I had to find a philips tv repair to take it into....got lucky because there was one close by. Come to find out it was some board inside that cost $400 to repair. I thought cool it's cheaper than a new tv! Worked great until about 2 weeks ago the tv turns on and the light is green and picture pops up a minute later. Oh boy more problems! As I sit here right now my tv no longer has a picture. The green light is on but nothing. It's funny because we had it repaired this time last year. I'm fed up and buying a new tv!

Switch the TV on: Press the power switch A on the front of the TV. A green indicator on the front of the TV lights up when the screen is on. If the indicator is red, press the
-CH + keys on the remote control.
The green light blinks every time you press a key n the remote control.

My Philips plasma only shows half the screen. The other half is just blacked out.


This model has PiP (Picture In Picture), find the button on the remote or check manual, this mode is most likely turned on and is being shared with one of the AV channels, or try turning on a plugged in SCART device to see if this picture shows on the other half of screen.

You have sound but no picture. Green power light is on and NOT flashing. You get a screen flash or flicker on power-up or even a minute of screen before going all black. It is your inverter board. Common problem on LCDs (maybe more so on Phillips?). They are easy to replace (unplug-plug) and are available on the net.
