42pf220a/37 Philips TV - Red Blinking LED wont turn on

HI
My TV started to act funky when I turned it on a couple of months ago. It makes a cutting in & out squeaky noise with the sound and the picture cuts on & off until it seems like it catches itself and gets warmed up. The problem has gotten worse and now the tv will cut off and a blinkging red LED will come on the front of the tv. It blinks 6 slow blinks then 3 fast blinks. If I unplug the tv for a minute and plug it back in it seems to reset it and sometimes I get it to turn back on, but it does do the cutting in & out thing. What seems to be the problem, is there a code book for the way the LED is blinking to know what is wrong, is it something I can fix myself?

Hi,

Unfortunately, the only way to Reset the TV is to keep it unplugged for Few Minutes.You actually did this many times, However, it would still never solved the Problem.This is an Internal Failure which needs you to Open the TV and check Components. If you have tools like Multimeter and experience, i would be glad to assist you .

You would need Schematics as well. So, we could also get that from a Service Manual. Make sure that you need to do the Repair perfectly as a small mistake could Damage the TV.

Let me know,if needed further assistance,

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

This particular blinking code usually signifies a pair of capacitors, 3300 uf 10 V, that are located on the power supply board. A visual inspection usually shows that the tops of the capacitors are bulging. If the caps are the problem I would strongly advise that they be replaced with a better grade of capacitors.Once this is done you will also want to ensure that you have the latest firmware upgrade from the Phillips website. If you have the experience and the tools to do the repair yourself you will want to set aside a bit of extra time as the power board is well buried inside. If you are going to have to pay a repair shop to resolve the issue you should have them give you an estimate first. Unfortunately this can be an expensive repair because of the difficulties in getting to the board. With the price of flat panels dropping over the last couple of years the cost of replacing the TV may almost equal the cost of the repair.

Good luck and thank you for allowing us to help identify your issue.

    There will not be anyway around getting the TV to work without getting it serviced. It is quite possible that if you keep trying to use the TV with defective components inside the result will be more components becoming defective and the cost of repairing the unit will keep rising.

Hi



Thanks for using FixYa. It is due to the high voltage shutdown which might be exceeded 33k and the unit shuts it self down to protect other parts being damaged. Also please check power supply regulation and horizontal circuits. If these are fine then it means Small Signal Board has gone bad. You’ll need to replace Small Signal Board. It will cost around $300+. As this board requires special set up, you’ll need to contact a qualified TV repair tech. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

Rylee

Philips 42PFL7403D/F7 LCD TV. red light blinking where the on/off light is. TV will not turn on.


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty.
Counting of number of blinks to Philips TVs is entirely different to that of other brand TVs. It is not a direct count procedure. The site have details about how to count the number of LED blinks [Fault Codes] to Philips brand TVs are given; along with details of the faulty circuit location.

Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.
