One very common problem encountered on many Philips models, old and new, In some cases, the SSB board has to be replaced as the resistor on the PCB on the back of the CRT had to be fixed. In other cases the Y Sustain board had to be replaced. If the problem is not due to these two issues, then the capacitors will need to be replaced as they only have a fixed guaranteed life. Thus, it would be wise to take out an extended warranty on Philips due to this common repair issue which often occurs after the limited warranty has ended. Or you could just call your local repairman. There are lots of websites on how to fix it yourself on google. There could be many reasons. Hope this helps!

The TV is in some kind of protection mode, the blinking LED show you an error code.
Try pressing 062596 and then press menu button (do these in quick motion, don't let them to time out while keying)...see what happens
I also heard that this problem appeared with some people because the of the burnt fuse in the TV. To fix that it has to be taken to the tech shop. mecry.gif
And yes I also heard about this issue many times, seems like this TV set is very popular with this kind of problem.

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...

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
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.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Could be an open internal fuse or power supply failure. The serial number is immaterial.
