Question about Philips 30PF9946 30 in. HD-Ready Plasma Television

2 Answers

No picture and No sound

My Philips TV 30PF9946 is less than 3 years old but it is broken suddenly. No picture and No sound. The power LED (red and green) comes on without any problem. I contacted Philips tech service and they gave me the contact of local TV repair store. I brought the TV to the dealer and waited for 2 weeks to get the result of diagnosis. The dealer told me that I would have to pay $4,000 to have my TV repaired. They said that they would need to replace an inverter, which will cost them almost $4,000. I purchased it at $2,000 about 3 years ago. Unreal!! If you have a solution, I would like to know. Thank you.

If you sure with the problem, try to get the part nunber from the service or the costumer service.
Try to find that part on the net, or a service who repear inverters.

Re: No picture and No sound

I have the same problem here with my Philips 30PF9946/37

I'm not sure this can be diagnosed as an inverter failure, unless there is a another inverter board in there I'm not aware of. The only inverter I found (actually two) in this unit is the pair of KLS300A1 inverters which drive the CCFL tubes.

Since I personally get a green power and light AND the CCFL backlight comes on, it seems unlikely that the inverters have failed.

Would love to hear from anyone who can ident the failure in these units - there's certainly a LOT of these around that have failed in exactly the same way.

No Picture & No sound. Red LED, Green LED, Red LED.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

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.

Black screen with sound. Problem on every channel.

Sound no picture or shut down Power led starts green then a short amber then turns RED . If your power supply can be confirmed to be go you have a bad Inverter board. Per the manufacture this part comes only with the panel . Not cost effective . But if you go to you will locate an inverter for $ 169.99 . I had the same problem and the inverter repaired the set . Note there are similar error codes but from what I can see from all of your complaint I do be leave that your Inverter is bad . Good luk
