We have a Philips 50 inch plasma TV model no. 50PF7320A/37. When we turn it on the green light comes and then we get a second click and the flashing red light comes on. We have turned it off, unplugged it and waited and have on occasion gotten it to come back on. We are now at the point where it will not turn on at all. any suggestions?

Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.

My "POS" philips wont power on. I called customer service, they told me because the warranty is expired that they could not help me at all. In fact they said they werent "ALLOWED" to tell me anything. I am so angry i found a site that wants to bring a Class Action suit against them. Pleasecontact them at http://www.classactionfaq.com/defective-products/plasmatv/ Lets make them pay!

Philips TVs **** - whoever said "Just buy a new power board fix ur tv" obviously works for Philips - again, Philips has horrible products that break and no customer service. Everyone that has ever purchased a Philips TV complained about it online. I wish I knew before I bought the piece of broken **** sitting in my living room.

I found that about 5 capacitors "pop"ed and that is why it just clicks. I ordered new capacitors at a cost of $12, soldered them in myself and I have a working tv again. Be careful around the power supply, there is high voltage. You can search for a new power supply board online too which is cheaper than the repair from the shop. my power supply board was $120 online if I wanted to order the whole thing.
nice job... thats the most common problem with all LCD tv's now

Philips 50 inch plasma tv no video but has sound

When you try to power up the unit, it just makes a clicking noise and will not power up. We took it to a local repair shop, and was told we need a new power supply that would run $425.00. This seems like an expensive fix. Of course the TV is no longer under warranty, the warranty expired in May!! Help! Thanks!

I have the same tv with the identical issue. I replaced the capacitors that were bad on the power supply board. You have to be comfortable taking the tv backing off and removing the power supply board which is located in the top middle if you take the back metal cover off. Once off, look at the capacitors on the right side of the board, you should see black goo on top of them. Those are the bad ones that need to be replaced. Maybe you have someone you know who can fix that for you or you can simply order a new power supply board online for about $130 and replace the whole thing yourself. either way, it's cheaper than the shop. Some power supply boards are much more expensive than others, so make sure you have the right part number. Best of Luck and be very careful of you try this yourself. There is high voltage on this board so only touch from the outside of the board. Again, have an expert do this if you are not very comfortable doing it.

MY 50 PHILLIPS PLASMA BLINKS THE RED LIGHT 6 TIMES FAST AND 3 TIMES SLOW CAN SOMEONE HELP ME IT DOESNT COME ON AT ALL UNLESS YOU UNPLUG IT SEVERAL TIMES
Posted by plase2b on
There Are 2 10 Volt 33000mfd. Electrolytic Capacitors At The Bottom Of The Power Supply Board,
They Are Right Next To Each Other, They Should Look Swollen ,They Should Be Changed To 12 or16
Volt Versions,This Seems To Have Worked In Three Sets I Have Seen.

I have a Philips 50 inch plasma tv. The light is blinking red and it won't turn on. What is wrong?
Posted by smithsteph... on
Most Likely the power supply board has a few capacitors blown.You can repair it by removing back cover power supply board will be at the center of tv.Look for caps that have a round top these are the bad ones replace with same value caps.You will have to take power supply board out.Be careful these power supply boards have alot of voltage store in them.

Turn on the unit and the relay clicks with a solid green light then the relay clicks again and the red LED blinks in intervals of 4x. The screen never lights up. Is there an error code that coincides with the 4x blinking? I am a bench tech in need of some guidance/help/assistance. Philips MODEL 42PF5321D/37 thank you, carl
Posted by Carl Carl on
The most likely reason for the no picture might be the back light is gone and needs to be replaced, now as for the LED light blinking on different intervals is because its diagnosing it self unfortunately the user manual does not have any information on this part only by contacting the Phillips customer support you might get a better idea, but check your back light first it may just be that. Also try to check your Manufacturer warranty repair.

My 50 Phillips Plasma TV will not turn on. It just makes a clicking sound and blinks a blue light.
I had a similar problem with my 42 in Philips LCD HDTV.
Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired ofcourse) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 yearsinstead of 10-20. The capacitors failprematurely due to a lack of preservatives. Unfortunately, they were installed in allsorts of devices and cause a wide range of failure problems. Here are some options for you.
1. Have it fixed by a professional $$$$$$$???????
2. Open your TV and find PSB. Checkfor faulty caps. If you find some (bulgedor leaking) bad caps replace the entire board. The entire board costs around $250 right nowbecause they are in high demand right now. They can be found at tv-part.com but supplies are limited.
3. Remove and then replace individual faulty caps. This takes some soldering skill. Caps are inexpensive and if you can take care of it yourselfit will save you hundreds.
I have a tip/tutorialon this site that may also help. Itgives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing the Philips Turns/shutsoff on its own problem. I'mworking on uploading pictures to help guide people though the process aswell. Let me know if I can do anythingto help. Hope this helps and Good luck. Kaufman605
