Hi all. looking for the schematic of the power board on the Orion PM4202
plasma TV (also known as the Vision PM4202). Fault is it wont power up,
relay clicks off after about 6 seconds and it goes into standby.

Any assistance greatly appreciated

Thanks in advance

Hi Graham

Could you mention which PWM circuit is on your power board?. This wil
probably clear if there is a fault or not in your power board. Based o
your comments, I would think about other problem rather than powe
board. The PWM number will help...

Regards

Hi John, thanks for the response. Do you actually know this chassis? , this
set has 2 very large power boards in it , simply marked SP-2000 power 1 and
SP-2000 power 2. Both boards are made by SM-TECH Korea.

Its difficult to say which PWM circuit is in use as there are so many
individual power circuits on these 2 boards. I can verify though that the
1st board seems to be supplying 380v to psu 2 and most of the voltages off
PSU 2 seem to be more or less correct with the exception of the 12volt
lines. Its difficult to just jump in and say the 12volt line is at fault as
it may be low due to the unit not firing up correctly due to excessive load
elsewhere. I really need to get hold of the circuit diagram of the complete
power supply circuitry if anyone has it.

On a seperate note, if anyone is looking for the schematic for a Hyundai
HPT4240 (Badged LG model) i do have the PSU schematic for it , just drop me
an email. (it took me about 3 days scouring the internet to find it )

Where did you eventually find it?

On a Russion schematics site, cant remember the name but i will post a link
up here shortly to some websapce where the file can be downloaded from. You
will need Acrobat Reader and Korean font set installing to view it.

Dear Graham,

Re your Orion PM4202 did you find a circuit for it?

I have one with a similar problem, relay clicks off after 2-3 seconds.

Any help or comments gratefully received.

Best wishes,

Geoffrey.
