On philips televisions -- they have an internal computer that controls the software
if you get the code one red flash then two short flashes -- the software is out of date and you can get a free upgrade online
the power doesnt work from a problem with the power board-- you can get a new board for 300 or a refurbushed board for about 130---- most television places have no clue how to fix these televisions
tv repair is all about making the most amount of money - the easiest way =--- when a board goes bad -- it usually is one part not the whole board -- they can make fast cash by changing a board instead of finding out what the real problem is---
for all codes or flashing lights -- call customer service and ask what the code stands for -- each code represents a specific problem and they can direct you in the right direction to fix the television ----

Had the same problem - green light on for 2 seconds, then red light flashing 6 times over and over. Since I don't know anything about capacitors and resistors, I took it in to a Philips service center (nearest one over 50 miles from my house) and they replaced the power supply. Cost me $250, and my TV is only 18 months old! I'll never buy Philips again, but at least it works now!

Pitbull4747 I have the same problem with my Philips 37"LCD and I contacted Philips-there solution- have their service tech fix it (@$100 per hour+ parts if needed). My suggestion- open back of TV (all 23 screws-took about 10 mins)and replace the 2 fuses (Radio Shack $6.00). If problem not solved, then you have a tech look at it.

If you turn of the power (pull the plug ) and plug it in again it works

A 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

Probably a failed main power supply. There are at least two supplies; one that keeps the remote function alive continuously and the second that is turned on when the set is ordered to operate. The smaller supply is a low voltage circuit and that is providing your error indication.

I found the above web site pretty helpful, too (AVForums), and have spent a couple of hours reading that thread.
Seems like the capacitators are often why the power won't come on. Also, some people mentioned that holding a blow dryer to your TV will make it come back on. According to the tech-savvy people that could mean that your "solder joins" are cracked. So when they're cold they'll contract and lost the connection,and when you heat them up, they expand and reconnect where they are supposed to. I'm not tech savvy and this doesn't explain much to me, but it's interesting, and I'm sure somebody will go "aaah, I see...."
I'll quote a post from AVForums:
"The main components that wear out are the capacitors which, with aminimum amount of electronics knowledge and a suitable soldering iron(you need one with a tiny point, preferably a butane gas powered one)and a powerful magnifying glass. This must be self supporting or onethat hangs from a neck cord.
The capacitors and any other parts you need can be purchased very, verycheaply from rswww.com and they offer a free delivery service or, foran extra fee, a next day service!
When you remove the back panel from the TV, you will see a few circuitboards and you need to locate the one for the power supply.
On mine it is really obvious as it is situated at the top just left ofmiddle. They all have numbers printed on the circuit board. Mine are2662 (25V 1000 uF) 2663 and 2664 (both 50V 100uF)
The ones originally fitted are '85 deg C' but it is best to replacethem with ones that are '105 deg C' because they will last longer.
These '85 deg C caps' normally have a guaranteed life of of 1000 hours,whereas the '105 deg C' ones have a guaranteed life of 2000 hours!
This being the case, when Philips build the sets they know that theywill probably break down after a minimum of 1000 hours of use. If wesuppose that the caps last for twice their minimum life span (2000hours) and the TV is switched on for an average of 5 hours per day overthe year one, ore more, of them will probably fail in the secondquarter of the second year.
With this knowledge, for high cost items such as this, you would alwaysbe wise to take out an extended warranty and Philips, or any othermanufacturer, should be obliged to include an information card warningconsumers of this fact!
The Aluminium Electrolytic - Radial capacitors in question are,usually, 2 x 100uF. The voltage, I believe, depends on the screen size.My 42" screen requires 50V whereas the 32" version uses 25V caps.
There is also a larger 1000uF capacitor, of a similar type, that willbe sighted close to the other two. This seems to be 25V, whatever thescreen size!
The only thing you must remember when replacing these caps is that thelonger leg on the capacitor is 'Positive' and the shorter one is'Negative' and you must ensure that you do not damage the circuit track!
If you are careful and have a steady hand it is quite an easy job butif you are not too sure, you will probably be able to find a localrepairer that is able do the job.
However, you have to beware of the Companies that offer a service wherethey come and collect the tv for a set fee, usually just under £100!They then work out the cost of the repairs and, if you give them the goahead, they deduct the amount paid from the overall repair cost.
I have looked into many of these and, even if you agree to the repairestimate, usually in the region of £300, they never seem willing toguarantee the repair for longer than three months, six months at thevery most!
When you consider that these components cost a matter of pence you can see the value of trying to repair it yourself."
