IR sensor not working on Philips TV (32PFL5403D)

I have a Philips TV (32PFL5403D/F7) and the remote control is not working anymore but I am sure the remote control is not the problem. I noticed that the LED in the TV's lower right corner does not blink anymore when the buttons on the remote are pressed. The LED used to blink even when using different remote controls from other devices. How do I change or repair the IR sensor? I have not called the Philips customer service because I do not have the receipt as the TV was a gift.

Normally, this happens when the TV detects a bad circuit board and goes into " Protection Mode ". The blinking red light should be a error trouble code. I don't have the Service Manual on hand for your model number to tell you what the code means. Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.

I hope I shed some light on the subject for you.

IR sensors are tough devices firts make sure that your remote control is working view its ir led light using your phone camera you should see it flashing..another test is puting it near an AM radio ,you will hear an interference when you push any key. then the crystal is all right.Replacing the IR sensor means you really have to unsolder it from the circuit board and fing a replacement..I hope its just one of those cold solder ang not the IR sensor..Good luck.

Need to find out a part # for my philips 52PFL7403/f7 for the ir sensor

Join Date: Nov 2011 I have a Philips 47PFL3603D/F7 with the same problem. It was the IR sensor board causing the problem. You can search online to find the board, which almost everyone will most likely not have in stock, and cant be ordered. The part you need is this: 313926859181 IR Remote Sensor.

Models it will fit are as follows: Substitute Parts 313926859182
Known Models

If you can find the board, great! A replacement board costs about $12.00. If you can't... we'll there is something you can try ; )

Either way, if you know it's the board, what's the harm in trying?

Remove the back from the TV. You can actually leave it on your stand to do this if you can spin it around to gain access to the back of it. Be sure to unplug everything first!!!

Looking at the back of the tv, the board will be located in the lower left side by the speaker. It will have 2 cables attached to it. Remove them, and take out the screw or two that holds it in place. There will be a plastic tab that keeps it in place also.

Take your fingernail and bend the tab back, and the board should come free. After that you should be holding the board in your hands. The side of the board with the connectors on it is the side you want to manipulate. There will be a tiny surface mounted capacitor beside one of the wire connection sockets. Take a utility knife and scrape it off/ you could use a soldering iron but it should come off very easy with a knife.

Plug it back in, and give it a try! If it works... great! If not, find a replacement board, and try that.

Hope it helps someone!!!! quote.gif

Volume and on/off won't work on remote. Tried uplugging tv, take batteries out of remote, covering remote sensor on tv, still not working. Is it the remote sensor? Can change channels with the remote.

Remote control buttons have a special contact underneath the rubber button that connects to the remote board inside the controller when you press the button. Sometimes the contact wears off or becomes mis-aligned so when you press the button it does not hit the correct spot on the control board. Sometimes you can use a fine tipped screw driver and pry out the button and make sure it is properly aligned with the contact inside the remote. If you do not feel comfortable doing that, you can either purchase a universal remote for cheap or just use the buttons on the TV that do not work on the remote.

I believe my ir sensor on my tv is no longer working, I have seen on the internet where several people have replaced their own. Please tell me how this is done, and where I may order/buy one

Did you verify that the remote is putting out the signal?
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

You can try to see if he has the IR receiver board in stock if it is bad for sure.

My remote has stopped working. We have replaced the batteries with no luck because of this we cannot switch between sources My TV is a Philips 42" Model # 42PFL3603D/F7 Serial # VA180905005250

The IR remote sensor in side of the television need replacing, this is the sensor that receives the commands from the remote and relays them to the microprocessor of the TV. Have the remote sensor replaced.
