Question about Philips 30PF9975 30 in. LCD HDTV
After turning on it clicks, the standby led is green after a few seconds it clicks again and then the standby led turns red and flashes continuously there is no sound or picture
that specific flashiing is the software in the computer, the television has inside
you need to go to the philips website and download an upgrade software repair it is free-- put it on a thumb drive without any other things on it---- the television ,must be on to install --- turn it on with the remote and then insert the thumb drive-- the television will run a scan--- then turn off television and wait a few minutes-- turn it back on with the switch on the side of the unit-----
the power problem is something else--- the power board sounds like is going bad--- a new one is around 300-400 and a rebult unit is around 100 --- you can find them on partstore.com
this television is poorly built -- when you get the new board it is easy to install -- before ordering a new board -- check the fuses on the board-- there are two fuses -- one is 1amp and the other is 5amp -- both are slwo burn fuses

The TV is on protect mode.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.
If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.
Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

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.
