this is common issue with this model and through your troubleshooting is tied to y main board. blinking led on logic main in normal operation. when replacing y main always good idea to replace y upper and lowe buffer boards as they complete a circuit and sometimes replacing one without other could cause additional failure on remaining boards

Hi tileman5,
Your 7 blinks (error code) means that your 8.6 vdc in the power supply section is faulty.This was sense by the standy-by power supply's initial test. This voltage is easy to locate in the power supply board, each output voltage is written in the board itself. Concentrate in its regulator circuitry. Look for open fusible resistor, shorted transistor and leaky/dried capacitor. The unit is disable unless you fix this 8.6vdc fault.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Good day!!!!If the reset is not work the problem could be the inverter board found inside the TV..When you open the back cover of your TV by unscrewing it..After that the inverter board become visible.This is the sample picture of inverter board:11_29_2011_4_52_34_pm.jpgAfter you replace that board your TV back to normal operation..Hope it helps..

High probability that a (too) cheap component called a capacitor, has lost capacitance and gained losses internally.This leads to random problems with the start-up and finally with the continuing operation of the main power supply.This Philips-branded set, if less than ~ 3 years old, was built by Funai, the least of all Japanese electronic companies.Since this is a common problem in 'switched-mode' power supplies, you should be able to 'score' a replacement supply from either Funai or a Philips service center for somewhere between $100-$200 dollars and since these supplies are often made by companies other than the branded name on the set, they are most often plugged into the boards they service and can be replaced without a soldering iron or no skills other than common sense.I'd recommend unplugging the set, removing the back panel, looking for a smaller board with larger than average components on it, the latter consisting of cylindrical parts mounted both vertically and horizontally on the board (capacitors) and block-like parts wound with copper wire with black cores (transformers & chokes).Also found on this board will be one or more larger aluminum 'heat sinks' that dissipate heat from semiconductors mounted on them.This board should be visibly related to the incoming AC line.There may be two smaller boards with the second related and plugged into the plasma display tube; when this one fails, you will likely still have audio but no picture and is probably still working.If you are concerned about pulling plugs, either mark them (your own system) or take photos of them from several angles for reference before removing any plugs.The part that often cause this kind of problem (capacitor) normally fails internally and may not show any signs of being sick such as bulging or chemical discharge and may not be detectable without the use of a capacitance meter and is mostly in the range of 4.7-100uFd/50VDC. The reason waiting an hour or so for the supply to start up is that when this part fails, it also becomes very sensitive to temperature changes so may be pulled back toward a value of capacitance that allows the supply to start up.If you are curious, you can try placing a fan toward the rear vents of the set or alternately, using a hair dryer to blow heat into them.One of these will cause the supply to start working again; heat or cooling will cause the cap to shift its value enough (depending on where it is electronically) to either further delay or speed up the operation.

Hi,

Your unit is a Plasma TV, it hasn't a bulb.
The symptoms you've described is caused by faulty upper Y-scan drive. It is a rectangular board located at the left side of your unit(if you are facing at the back panel). You have to replace this board to resolve the issue.
You can do it yourself because no soldering required, let the unit unplug from the outlet for 1 hour to drain the voltage from the power supply before you replace the board. Pull-out the connectors from the existing board, put-in the new board, re-insert the connectors and you're done.
I would advice you to check the actual part no. of your board that is printed on the white sticker on the board itself to get the right replacement online. Click the link above to see how it gonna looks like...

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

7 blinks indicates a bad buffer board, usually I replaced the Y board and the buffer/s about $500-600 in parts. but before you buy anything open the set and look at the power supply if you see two capacitors that look swollen , bulging on top they need to be changed and may solve the issue. the power supply is middle top . If you are not wanting to repair it yourself then know that you do have some circuit board repairs needed.
thanks

make sure you didnt put them in backwards
electrolytic caps are polarized, meaning they only will go in one way.
there is a stripe down one side and should line up with the markings on the board.
if theyre ok, check you didnt solder something else with a drip or forget to plug in a wire.
reseat all wires, especially the flimsy (careful) little one that goes from the main board (with a/v jack panel) to the panel (screen)

Hey mate, very common in all makes of plasma TV's. See this how to video on to fix it, the video is for a hyundia but it is the same for your TV. http://www.youtube.com/watch?v=9NPobj0_GSo
It's pretty easy, just get a soldering iron and take your time, best of luck. Bro
