Re: Problem starting a plasma
When it looks like its going to start up and it dosent then its an indication that one of the sweeps didnt start up. When you hit the power switch, the power supply sends an ok signal to start up the horizontal and vertical oscillators. When these start up they go to there respective drive circuits and then the vertical will send a signal to the power supply to keep on going so then the horizontal circuit starts up and sends an ok signal to keep going so then the set comes ob,\. If one of the two doesent start up and stay running then the power supply shuts down. To troublwe shoot these sets you need a service manualo and a good multmeter and a scope wouldnt hurt slso. This set has no user servicable parts inside of her so you need to take the set to a pro to assist you in the repair. Good Luck

Remove Mains Plug and press Standby switch from LED Panel for 30 sec. Press Input & Ch Down Switch from LED panel and plug in and start LED LED will start and "K" will appear on screen Press Ch Down & Vol Down switch at same time You will get 1/10 page on screen Go to 9/10 page by pressing left & right button from remote Select EEP and press Ok button from remote After 30Sec remove main plug and restart LED.
This is likely a heat issue, and the CPU of the tuner is instructing the power board to switch it off for reasons related to over heating. Check that a fan ventilation improves the problem. The solution is not easy but maybe adding a fan to the tuner CPU can fix this issue.
I found that by simultaneously holding down the remote control "power" button and "volume" button for about 30 seconds the blinking light would go out and a solid green light would come on. Even though the solid green light came on the unit would still not power up. After doing this several times however the unit did finally power up in a normal mode and appears to be working again
That would be the balance switch, should be located rear right under the main board. over time the switch becomes jamed in the on position and the machine always thinks its off balance. $4 to $10 for a new one.
The problem is in the standby power supply. the standby power supply generates the 9 volts and the 5 volts requird by the tv. If you measure the 9 volts source, with only the red light on, the correct voltage is 9 volts. However if the 9 volt measures 6.5 to 7 volts it is too low and the startup relays cannot operate. My set is a model 42FR9954/17S. In this set if capicator, 2603, is heated the voltage climbs to 9 volts and the relays work. If cold air is applied to the capicator the relays fail to operate. Replace capacitor 2503 and the problen is fixed. This capicator is: 47 Ufd, rated @ 450 volts, and is 20%.
I have found this on a site and am in the proccess of trying to mend my plasma PF9964 as it started to take longer and longer until it stopped coming on. I've got the back off so I just need to un solder capacitors and replace.
Here's the info I found.
Bad power switch circuit
If you have this problem with your Philips 32PF9964: When I switch the TV on, it appears as though it is going to start i.e the green light comes on, then after about 10 seconds it switches itself off and the standby light flashes red. It takes 10 /12 times before it starts and is getting worse.
This is the solution:
The problem is three caps.
Change the cap 2663, 2664 both 100µ/25V
and 2662,1000µ/25V. After you have changed them your TV will work again.
You will find them easy if you unscrew the back on the plasma TV.
