Re: Philips 50pfp5532d goes into standby after about 1 minute
Many thanks for the service manual. Maybe I'm missing something, but I can't find a schematic of the SMPS in there.

Re: Philips 50pfp5532d goes into standby after about 1 minute
Many thanks for the offers of help.
I eventually managed to get the TV back up & running, but not the way I would have liked.
Unfortunately, I couldn't find a schematic to the SMPS, so ended-up swapping all the output voltage capacitors (C8030/C8031/C8046/C8051/C8042/C8084/C8052/C8047).
None of the capacitors showed any visible signs of failing, but obviously at least one was leaking.
If anyone has a schematic to the SMPS I would be very interested for when it fails again!Leave a comment:

Re: Philips 50pfp5532d goes into standby after about 1 minute
The green LED on the SMPS board is on and steady at all times and exhibits no fault codes.
The TV will occasionally stay on for up to 10 minutes, other times only a matter of a few seconds before it shuts down. A few times it has gone into standby mode then turned itself on again(!).
I've noticed that the 12v rail is sitting at 13.5v; is that relevant/critical?Leave a comment:

Philips 50pfp5532d goes into standby after about 1 minute
I have a Philips 50pfp5532d plasma TV which powers-up fine, then after about 1 minute goes into standby (red light). I can switch it on again no problem and get another 1 minute before it again goes into standby.
No bulging caps on the SMPS board.
If I unplug the x sus and y sus boards the fault still remains.
Any help would be most welcome. -

Re: JVC VM-42V31 plasma goes to standby flashing Red LED
Still no joy with fixing this
Does anyone know what the LEDs on the power board indicate? That might at least help isolate the fault.Leave a comment:

JVC VM-42V31 plasma goes to standby flashing Red LED
My JVC VM-42V31 plasma has suddenly developed the following fault:
Switch-on - steady green front panel LED comes-on. All 3 x power board LEDS come-on
After about 10 seconds the power board relay trips, LED8001 and LED 8002 on the power board extinguish and the front panel LED changes to a flashing red LED (flash rate - aprrox. 1 per second).
I've unplugged both the Y-Sus and X-Sus boards but the fault remains the same.
Any suggestions would be very gratefully received.
Many thanks. -
Re: JVC Plasma VM-42V31 stuck in standby
Thanks for all your help guys, I've finally got it working.
Capacitor 8031 on the SMPS was faulty (1.0uF 600VDC) - it was very slightly bulged at the sides.Leave a comment:

Re: JVC Plasma VM-42V31 stuck in standby
I've just noticed, when the relay trips-out the red protection LED on the power supply illuminates.Leave a comment:

Re: JVC Plasma VM-42V31 stuck in standby
No, exactly the same with the X Sus and Y Sus boards unplugged from the PSU.
One bit of misinformation I gave initially, after about 5 seconds the steady green LED changes to a flashing green LED when the relay trips-out.Leave a comment:

JVC Plasma VM-42V31 stuck in standby
My JVC VM-42V31 plasma will not turn-on.
When I press the power button the green LED comes-on and the relay on the power supply board clicks in. But after about 5 seconds the relay trips-out and the LED turns red. When the relay is activated there is a slight fizzling sound from the power supply but that may be normal.
Any ideas would be very gratefully received. -
Re: Technika lcd 32-207 intermittently sticking in standby
The voltage is 11.3. Much as I really don't want to go through the hassle of it, I think I'll end-up returning the board

Re: Technika lcd 32-207 intermittently sticking in standby
24v2. All voltages are pretty much spot-on apart from the 12v rail.Leave a comment:

Re: Technika lcd 32-207 intermittently sticking in standby
OK, if I unplug PL804 (12V supply to main board), all voltages on the SMPS come-up. However, the 12V rail measure 11V3. The main board is fine as the TV works perfectly with another SMPS.Leave a comment:

Re: Technika lcd 32-207 intermittently sticking in standby
The TV is fine (apart from the SMPS board) as I've tested it with a good SMPS from another TV.Leave a comment:
