Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

The standard way to find out whether the issues on a tv are hardware related or settings environment related is to perform a reset to factory default through the menus available from the remote controlIf the fault persists after a reset and rescan the fault is almost certainly hardware related and will need the attention of a competent technician

Time to replace the screen, it is going bad.

Replace the screen, it is going bad.

if rebooting the monitor would do no good, try to get a spare monitor cable if the same flickering issue took effect. If it is so, then call your pc provider to repair your monitor..

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

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!!!!

There are plenty of places you can look. Shopjimmy.com. Tiger parts direct. Encompass parts are just a few. Just google the part# and some part suppliers will pop up.

Hi
First thing to do is check your remotes by aiming them at a camera or the camera on your mobile phone then pressing any button you should see the led on the remote light up white, If this happens then your remotes are ok and you would then need to look further into the problem.
I would suggest the remote sensor in the tv being short or you may need a replacement AV board (the one that has the inputs and scart sockets are on )
Hope this info helps
