Question about Philips 42PF9631D 42 in. Plasma Television

2 Answers

Blinking red light and tv will not turn on.

I have a Philips Flat Screen TV, Model # 42PF9630A/37. I believe it is a 42" screen. Today, it would not turn on. It has a blinking red light next to the green light that tells you when it is on. I have unplugged it, several times, trying to reset it. When I do this the green light will come on briefly then it goes to the red blinking light again. What does this mean?

The only thing I can suggest outside of taking the television to get repaired is a hail-mary firmware update. To be honest, the firmware update process is fairly complicated and lengthy. You can download the firmware and find instructions for it here.

Look on the right hand side for firmware information.

This TV is likely outside of its 1 year manufacturer's warranty so you would have to pay any and all repairs. Before deciding to do a repair you might try calling Philips. For a while they were offering a service to customers like yourself with out of warranty units. They would offer to sell you a more up to date model at a discount. I'm not sure they still do this but its worth a shot.

Hope that helps!

I have a Philips plasma 42 with black lines across the screen

I would first check if there is an available firmware upgrade for your model .Upgrade requires you to download firmware from philips website.Then transfer it to a memory stick .Then use a memory stick reader to plug into tv for firmware upgrade.Other wise the set would probably need repair .Possible a bad SSB board or another issue

I have a Philips 42 in. Plasma Television model#42pf9956/37. When I turn it on it goes right back off. What the problem.

The TV is going into Protection Mode. When a failed part occurs inside the TV, it will turn itself OFF automatically to prevent further damage to other components. I'm sure the red light is blinking a code also.
Most likely the problem is occurring on the Backlight Inverter Board or the Main Power Supply. The Backlight Inverter Board is what brings power to the screen. The Main Power Supply is what brings power to all the circuit boards in the TV.
I would use the warranty if there is any to fix the TV. The repair shop may charge a crazy price to fix the problem.
If you have some electronic experience and you want to fix it yourself, you can sometimes find a Service Manual over the internet for less than $20. It will have red light blink codes, diagrams, schematics, and part numbers for every part on the boards. Replacement parts can be found by using the part numbers for the search on the internet. Most parts cost less than $10. Whole replacement boards can be found at a good price at
