Ok 7 red blinking led, remove the back cover of the TV. Looking at the power supply in the upper left of power supply. If everything is working fine you will see a solid green led if there is an error, you will see this light blinking also. Right below this led on the power board you will see a list of numbers 1-13 this will give u the problems that this led flashing problems are. More and likely u will have a problem with VSET or VSCAN. Which is connected to the Y-Main and Y-buffers,( the board that is too the left of the power supply if u look on the small print on this board you will see that it reads. 42HDV4 Ymain and the 2 small boards connected to it are Y buffers. To be sure that this board is bad if the TV keeps going into error protection. unplug the power supply and wait for the led to stop flashing. Disconnect the cable that plugs into Y-Main from the Power Supply. It should stay running. If u remove this board and look underneath u should be able to see where this board is getting hot. Easiest fix is to order a replacement. Y-main assembly.

I have the same problem, except with a Philips 50 inch model 50PF9631D/37, except mine sometimes does 6 long flashes and 3 short. Here is what I found, after MUCH online and other research:

It is probably the Power Supply board. One other indicator that it is the power supply board is that if you unplug it for a minute or so, and then plug it back in, it might start up and stay running until you shut it off again (that is what mine would do). Mine eventually would not come back on after repeated unplugging. I have learned that the reason for this is leaking capacitors on the Power Supply Board. If they are really bad (like mine eventually were), the TV will not come on at all. The reason it will stay running once it is going is that there is a separate set of circuitry for the TV once it is going.

I UNPLUGGED my tv and waited 1 hour (for capacitors to hopefully discharge), and then opened up the back of the TV (all you need is a "Torx" (also known as star-head screwdriver, with 2 different sized bits (buy multiple bits if necessary, they are cheap and I don't remember the sizes).

PLEASE NOTE: Even unplugged, TV's have capacitors which store large amounts of electricity which can discharge quickly and kill you. Be very careful. One website suggested wearing special, high-voltage rubber gloves.

The Power supply board is the big computer-looking board in the center. I stared at mine for 15 minutes and was able to notice 2 capacitors with slightly bulged tops. I have learned that this is a common problem with these boards. All you need to do to remove the board (at least with mine) is to carefully (there is a little clippy thingy on the bigger ones) unplug the wires connected to it, and unscrew the screws holding it in with a phillips-head screwdriver.

I was able to find a replacement board at various places on the internet, but the best was BestBuyParts. I found they had 1 Original Board for mine for $300, an updated replacement for $300, and a refurbished replacement for $205. I ordered the refurbished one and will let you know my success when I get it. Interestingly, the original board was made by Samsung!

Interesting side note: I tried to simply replace the $1.00 capacitors on the board to save money, but they are REALLY hard to find. I finally found that the original capacitors, made by Samwha, are no longer sold as 105 degree celcius capacitors, but are now listed as 85 degree capacitors, and their 105 degree replacement is now back-ordered. I have also ordered approximate substitutions, to see if I can save the old board. Bottom line: It looks like Philips bought the board from Samsung, who got some bad capacitors from Samwha, and we all pay the price.

Finally, check to see if there is a recall. 12,000 Philips TV's with Ambilight have bad capacitors which are sparking and have been recalled. I doubt it is related, but I bet I know who manufactured those bad capacitors.

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 Plasma tv 42pf5321d/37 with sound but no picture

Thats the great sound of Exploding capacitors on either the power supply board. or another one in there. Now the set is in fault protection. It tried to warn you with the RED blinking LED that there was something amiss by shutting itself down. When you unplugged you reset the error and allowed it to do it again.

Best Regards and Smper Fi
