Monitor turns goes black and comes back on every 10 secs planar PX2210MW


The Planar PX2210MW is notorious for bad electrolytic capacitors. Specifically capacitor C804 on the power supply board. . This is a 1000uF 25volt capacitor. That capacitor was usually made by Hermei and it was purple. Normally, the top of a capacitor will be flat. When it fails, it will be curved upward and there may be some brown material leaking out.
If the monitor still will not work after replacing C804, the problem could be Q805 or Q806. These are located on the under side of the board. They are small black surface mounted chips. There are 8 pins on these chips. I have seen both AO4620 and APM4548A part numbers used. These chips contain a pair of MOSFET transistors. One transistor is n-channel and the other is p-channel. Look for a short in one of the transistors. I have repaired several of these monitors. C804 is always bad. How ever, in three cases, Q805 or Q806 was also bad 12c1ec2c-5a6d-4352-af31-150a0a92514c.jpg c9a53aae-2999-45c7-ad78-44ba51ac5a6c.jpg 795d93fe-9678-46c2-820a-767bea9babb0.jpg

Does anyone know where to get the schematic for the dv6550us motherboard?


The closest I come to an HP Pavilion dv6550us, on HP Support, or on the internet is;

Pavilion dv6550tx
Next inline is Pavilion dv6560us,
then Pavilion dv6450us

Not available to the public.

Do have a Block Diagram,

Both use the Fairchild Semiconductor Industries - FDS6679 - Power MOSFET, and Alpha & Omega Semiconductor LTD - AO4407 - Power MOSFET, in the DC - DC circuit; as far as I know.

Both are Obsolete, but there are cross match examples out there.
(FDS6679AZ for FDS6679, for one)

Indicates HP Pavilion dv9000 series, and AMD; but also matches up to the Pavilion dv6500 series,

Asking for a Schematic, do I assume you are attempting
Board Level Component replacement?

What SMD/SMT IC component are you trying to replace?
(Surface Mount Device/Surface Mount Technology. Integrated Circuit)

Motherboard chipset info, and processor socket info, for processor upgrade.
Same thing for Ram Memory upgrade.
It does use DDR2 Sdram (SO-DIMM), and at 667MegaHertz, to my knowledge.

What usually goes bad on the HP Pavilion dv2000 series, Pavilion dv6000 series, and Pavilion dv9000 series of Notebook PC's?

The cooling for the graphics chipset is inadequate, therefore the graphics chipset overheats, and partially melts the Solder Joints in the BGA surface mount.

Resulting in no graphics.

Power MOSFET's in DC - DC circuit go bad.

I need a schematic for a RF p300-1 amp. Im trying to replace 2 of the mosfet semiconductors that got fried.


There are no schematics for RF amps, normally RF uses standard IRF Mosfets. Can you decribe the area where they blew, Power Supply are usually N-Channel high current type. Outputs can be either N-Ch or P-Ch depending on the Power rail there attached to.

Blown channel


Its possible to repair, but you have to crack the amp open and prod around a bit. I found that the failure is usually in the power components or the MOSFET drivers. If you have 1 channel out, I would focus on the MOSFETS (if you dont know what they look like just Google MOSFET - they are the black 3-legged chips and are usually mounted to aluminum to disperse the heat). Some things to look for:
- burnt / melted solder traces (where the MOSFETS connect to the main board)
- disconnected leads (same place as above).

If you find any connection that looks suspicious, it wont hurt to re-melt the solder around the joint to make sure its a good connection.

Hope that helps...

  • 380 Watts x 1 @ 4 ohms BRIDGE <=1% THD+N
  • 75 dBA Signal-to-Noise Ratio
  • Peak Music Power: 250W x 2 (4 ohm) / 760W x 1 (Bridge)
  • 2 Channels
  • Continuous Power @ 4 Ohm: 125W x 2
  • Continuous Power @ 2 Ohm: 190W x 2
  • Continuous Power Bridged @ 4 Ohm: 380W x 1
  • Frequency Response: 10Hz-50kHz
  • THD (1kHz, 4 Ohm): <0.015%
  • Signal to Noise Ratio: >95dB
  • Dimensions: 11 13/16” x 2 3/8” x 12 7/8”
  • PWM Regulated MOSFET Power Supply
  • Balanced Isolator Input Circuit
  • Oversized Screw-Type Power/Ground Terminals
  • 2 Channel RCA Inputs
  • Speaker Level Input
  • Screw-Type Speaker Terminals

  • Bass Boost (50Hz, 0/6/12dB)
  • Selectable LPF (80Hz, -12dB/Oct.)
  • Pioneer 1-Year Warranty
I'm assuming the subwoofers were bridged and couldn't handle the power. Make sure you have atleast 300 watts peak power wattage.
