1. First, make sure the socket at the mains is working, try a different appliance to check. Next, try this - hold the menu button down for 10 seconds. TV should power up; you will have to turn off front panel buttons on menu.

2. You can also try plugging in the TV through the USB on its panel to a computer or USB charger, and it may work. However, this is only a temporary solution.

3. Powering down the set or putting it in standby may have allowed the power supply to cool. Weak capacitors often go out of spec when they cool, thus preventing a section of the power supply from firing up properly again. There is a simple trick...just warm the back of the TV with a hair dryer for 5-7 mins after you have unplugged the TV. Look for the little areas of holes in the back panel of TV. Use these as your guide at where to use the hairdryer, but don't hold the dryer too close (say 5-6inches away). (Make sure the dryer is on High heat). If the TV doesn't turn on after you have heated it up (like it tries to come on but then turns off) you need to unplug the TV again, this resets it. And repeat those steps till it works. Resetting the TV after it fails to turn on is the key. Also, just leave the TV on. Don't turn in off. Since it is LCD, it doesn't take much power...only a few bucks extra a month for your utility bill.

4. A circuit board may crack about some of the larger components mounted on it. You can inspect the PCB's for fractures, and then repair them. It may also be poor soldering that has failed. I would be checking for these things first.

5. If you want to go in for a long term solution, you can easily replace the whole power board or just change the faulty capacitors. You will have to open the back panel and take a look. You can make out which are faulty, because their caps will be swollen on top. Here's a sample pic (not same model):

Check the specifications of the faulty capacitors, and get the replacements from your local electronics shop. If you are comfortable with this, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out the defunct capacitors. Once that is done, solder in the new capacitors carefully. If are unsure how to do this, try to get a friend who knows how to do this kinda stuff do it for you, or get a qualified technician. Warning: If you do not have a background in electronics repair, or are inexperienced, get a qualified technician to do it for you.

REMEMBER there are very dangerous voltages inside a TV that can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECT THE POWER BEFORE YOU DO ANYTHING.

Hope that helps!

My 60 inch phillips tv, I turned it off the other night and now all i get when i turn it on is the power button flashing green. 6 quick flashes and then 1. I need my tv, plz help


Try a new Web search for your brand. Try looking for a Diagnostic trouble code of 6-1 and see if you can pull up parts of a Service manual using that search routine. Try Phillips trouble codes, Phillips Diagnostic Codes, or your model# in the search.

It sounds like it went into a default Diagnostic mode. If you have a Remote with extra functions it may get you into the Diagnostic menu.

It shut off in 2 seconds of turning the tv on


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors. This may be your problem
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps
