Hi Experts,
We have a Philips TV (see model) but when you switch it off it doens't come one anymore. The remote led doensn't blink and looks like the remore controll is not transmitting. I have found a solution what works only once a day. When we unplug the TV for hours and swhitch on the main switch (on the front) the tv will startup and works. As soon as we switch back to standby or on plug the TV we have to repeate this and have to wait for hours! If we try it in 2-3 hours or so the TV still doesn't work. It looks like a "condensator" has to de-charge fully before we can operate the TV again. Does any of you experts have any idea what part I need to replace?

If the TV has sound and no picture, it might be the timer settings. There is a fix for Philips 20PF5320 here

You have a 8.6v supply error according to the 7 error code being displayed, what you can try is when the set goes to blinking disconnect the Y sustain board (if looking at the tv from the back the board on the left) from the upper left side of the power supply, if the error code stops then you know your Y sustain board is pulling down your power supply and causing the error, if the error code continues you have a probelm with your Logic Board (located under your Small Signal Board) disconnect this from the Y sustain board and see if the error code stops if it does you know that the Logic board is bad, if the error code is still blinking then the 8.6v supply line from the Power supply is faulty and the Power Supply needs to be replaced

7 blink error is 8.6 volt error on that model. usually tied to y sustain board located on left side of set looking from back. disconnect y main from power supply and power on and if comes on verify power supply primary voltages located on label on pdp itself. if voltages present you would need to replace that board as not designed for component level repair. however if you find failed components like swollen caps or burnt ic's you could replace those. also when replacing the y main board there are two y buffer boards to left of main board that also would be recommended to be replaced at same time as they work as circuit and replacing one board without other could cause failure to other boards still in set

This is a common problem on these plasma TV's. The problemresides in the high voltage boards known as the X and Y Sustainboards.. You can purchase them here for a very reasonable price:

The above link is to a Y-SUS board. The X-Sus board is often the 2nd cause of failure and can be found here:

Totest which board is failing, you need to check voltage input to theYSUS board first... Input should be 120V from Power supply, outputshould be above 250V.. Do this test with XSUS disconnected. IF 250+Vexists, then XSUS is damaged. If not, then the YSUS is the faulty part.

From the information you have provided failed capacitors in the power supply is likely causing the problem. The safety circuitry shuts the TV set down when it detects a problem. This model of TV has over 2,000 parts which include millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Integrated circuits and transistors can go bad. This can cause other components to become defective, which can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. The repair should cost about $250 if carried into a TV repair shop. A small TV repair shop will often charge less than a large repair facility.
Hello, I came across several times in this type of malfunction, stems from primary circuit of the power supply unit. I solved it by replacing the 5W ceramic resistor. In another case I came across electrolytic capacitors that i had to replace in the same circle. I hope it was helpful!
