    I have a TH-42PD50U with a Power LED flashing ten times when power is turned on. Lost power in a storm and surged when power came back on (TV plugged into a surge protector). TV is located in Belize in Central America and am in need of proper circuit board to replace for repair. Will need to get part(s) in the states and provide to local TV repairman for fix. HELP!

I had the same problem and after many tests, it was the PA Board, as the expert said here. I purchased an used board on ebay for $4.75 and that solved the problems which came back to live.

I just bought a Panasonic TH-42PZ800U and had the same problem. 10 blinks and the TV would not start. Then after some trial and error I solved the problem!

Here is my (apparent) observation and solution:
I had only one input into the TV, which was my HTPC connected via a DVI-to-HDMI cable plugged into the Panny's HDMI 1 slot. *IF* the HTPC was already on, then the Panny would have the blink of death. *BUT* if the HTPC was off, the Panny booted fine (assuming I cleared the blink of death first by powering off the HTPC, unplugging the TV, and replugging the TV back in with the HTPC still off).

My solution was to move the HDMI cable from slot 1 to slot 3. After making this one change, everything worked as it should. No more 10 blinks of death. I could even leave the HTPC on and turn on the TV last, and it still worked. Tried this 10 times, worked 10 times.

I don't know if this will solve other people's problems, but I hope it at least provides some clues. I wonder if this is a fundamental circuit design flaw on the part of Panasonic, rather than a "bad batch of parts" problem.

Power front panel conectors on acer 915m08


This Foxconn 915M08-G-8KS motherboard made for Acer Veriton desktop computers?

http://www.sella.co.nz/general/computers/components/motherboards/other-motherboards/b1jnj6/

Do not know what the Front Panel header pinout is.

(Front plastic part of computer tower is the Front Panel.
Area of contact pins on the motherboard, that the wires (Cables) from the Front Panel connect to, is the Front Panel header )

CAN see by clicking on - View full size image - that the Front Panel header is to the Top Left corner of the motherboard, by the CMOS battery.
(View of mobo is upside down, in relation to how it actually sits in the computer tower case)

Shows me it is just the normal two rows of contact pins used in a LOT of desktop computer mobo's. (MOtherBOard)

If it were I, I would use one of the LED lights connected to two wires, and touch across each two sets of pins.

Looking at the motherboard as it sits in the computer case, there is a row of pins on Top, and a row of pins on Bottom.

In your mind start at the LEFT side of the pins at the TOP.
Number them from Left to Right.
Example, Pins 1, 3, 5, 7, and 9.

Now number the pins on the Bottom, from Left to Right,
Pins 2, 4, 6, 8, and 10.

Computer plugged into power, touch the two wires of the LED light, to Pins 1 and 2.
Computer doesn't start? (Power Supply turns on)
Go to the next set of pins.

I am willing to bet Pins 5 and 6 turn the Power Supply on.
No? Keep experimenting.

What will happen if you touch the WRONG pins?
N-O-T-H-I-N-G
You will NOT hurt the motherboard.

When you get to the correct pins, the Power Supply will turn on.
These pins are for the Power On switch.

Now go back through the pins with the Power Supply on, but DO NOT touch the pins that turned the Power Supply on.

When the LED light STAYS on, you have the pins for the Power On LED light.

If the LED light BLINKS, you have the HarDDrive activity LED light.

If Windows starts to load, and you touch the Restart switch pins, the computer will restart over again, and Windows will load again.

(IF this computer has a Restart switch. I do NOT use one, even for the older computers. Just press CTRL, ALT, and DELete keys at the SAME TIME, to restart the computer, or use the Task Manager option)

One pin left all by itself? That is for 5 Volts, and only used by the factory. Leave it unconnected.

There may also be a blank spot on the Front Panel header, where it looks like a pin is missing. This is the KEY pin, and is not used.
It is just to orient where the other pins are.

Worried about getting shocked?
There may be a small spark, as you connect the wires, I will gramnt you that.
But the voltage is 5 VOLTS DC.
In comparison two D cell flashlight batteries produce 3 VOLTS DC.

The harmful AC voltage is contained in the metal enclosure, of the Power Supply. Can't get you unless you pour water on it close up, or stick a metal rod through one of the ventilation holes, in the Power Supply enclosure.

Regards,
joecoolvette

By the by. You could be a lot of people's hero, if you came back, and posted the pins for what they do. Post in a Comment.

If my information is correct;

Orient the motherboard so that we are both looking at it in the same direction,
Processor to the top, Ram Memory slots to the right, white PCI slots to the bottom.

The front plastic panel of your computer that has the Power On button, Harddrive activity LED light, and Power On LED light, is the Front Panel.

The area of pins on the motherboard, that the wires from the Front Panel go to, is the Front Panel header.

The Front Panel header is all the way down on the right corner. Panel 1.

The Front Panel header, or Panel 1, is a rectangular block that is positioned lengthwise, across the bottom of the motherboard.

There are 4 pins across the Top, and 5 pins across the Bottom.

The pins are numbered.
They are numbered Even across the Top row.
Pins 2, 4, 6, and 8. (There is NO Pin 10. Just a blank spot)

They are numbered Odd across the Bottom row.
Pins 1, 3, 5, 7, and 9.

A) Pins 1 and 3 are for the HarDDrive activity LED light. (HDD LED)
Pin 1 is for the Positive wire. ( + )
{ Pin 2 is for the Negative wire. ( - ) }

If the LED light is dim when operating, turn the wires around.

B) Pins 5 and 7 are for a Reset switch, (Reset button), IF a Reset switch is used.
Pin 5 is for the Negative wire

C) Pin 9 is RVSD_DNU
Reserved Do Not Use.

D) Pins 2 and 4 are for the Power On LED light.
Pin 2 is for the Positive ( + ) wire.

If the LED light is dim turn the wires around.

E) Pins 6 and 8 are for the Power On switch.

For additional questions please post in a Comment.

Where can i get pyramid-9 PCB No BA41-00167A manual book for setting up power switch,hdd led,reset etc connection setting ???????????


Hello, i was made a search in google, i guess you must look it too, and a don't get nothing, but, I think i've a solution for you, according my own experience, i've installed 2 kinds of different MB, and, althoug there are different brands, the connection pins are the same, ie, the front panel connector that connect HDD Led, Power Led, Reset and Power, is a 9 pin conectors (really have 10, but 1 pin is cut for reference) and commonly is called PANEL 1

Then, i guide you

2 8
. . . . this will be 2,4,6 and 8 pins (from left to right)
. . . . . this will be 1,3,5,7 and 9 pins
1 9


Power Led + in pin 2
Power Led - in pin 4
Power Button # or + in pin 6 (It's no critic the orientation, it have no polarity, is a push buttom)
Power Button GND or - in pin 8

HDD Led + in pin 1
HDD Led - in pin 3
GND from Reset Buttom in pin 5
# from Reset Buttom in pin 7

THE PIN 9 has no connection

My vw jetta 98 turns but wont start what can it


check for a spark at the plugs if you dont have this then you will need to check that the ingintion coil has a live feed and and earth the pins 1 and 3 on the conector if you have this then you will need to check that you have a pulse from the hall sender this is in pin 2 of the conector check it with a circuit tester and the led should flash if it does then the ignition coil has had it if not then check for a live and an earth at the hall sender ( three pin plug on the distributor ) pins 1 +3 if this is ok you will need a new distributor also worth checkin for a live at both of these with someone cranking the engine if you loose the live feed under cranking the you will need an ignition switch

Problem with panel front conector in Dell Dimension 2200 motherbo


The following information is to assist you in performing the right connections. You should take precautionary measures such as grounding yourself and completely disconnecting the PC form any source of power.

This picture shows the connector for the front panel power button, reset button, and power and hard disk lights: an 8x2 pin connector with 1 pin missing:



0505a76.jpg
The table below lists the pinouts for the connector. The orientation of this table is the same as the picture above, this shows the top part of the connector. All the pins below pin 8 appear to be non-connected.


f07048e.jpg


Each pair of pins labeled Power and Reset goes to the 2 wires for the corresponding button. The hard disk and power LED wires connect to the corresponding LEDs, you need to ensure the proper polarity of the + and - wires for each LED or it will not illuminate.

The above information is for your information only.

Panasonic Th37PE30 Viera plasma stopped working


here is a complete list of all codes for panasonic tv's rgeardless of model if its panasonic it is these codes

1 Blink SOS: This shutdown operation is usually caused by a lack of communication between the A and the D boards.
1 Blink SOS: This shutdown operation may be caused by the improper connection of a SS board connector to the panel.
2 Blinks SOS: Pin 87 of the MPU IC9003 monitors the 15V line. During normal operation, the transistors Q9053 and Q9054 output a high to pin 87. If the 15V line is missing or shorted, a low is provided to pin 87. As a result, the unit shuts down and the power LED blinks 2 times.
3 Blinks SOS: IC9807 is a 3.3V regulator located on the D board. Its output is monitored by IC9003. If the 3.3V is not present at pin 86, the MPU shuts down the unit. The power LED blinks 3 times.
5 Blinks SOS: Pin 85 of the MPU IC9003 monitors the 5V line. During normal operation, the transistors Q9051 and Q9052 output a high to pin 85. If the 5V line is missing or shorted, a low is provided to pin 85. As a result, the unit shuts down and the power LED blinks 5 times.
6 Blinks SOS: Pin 90 of the MPU IC9003 monitors the status of the SC board. During normal operation, the transistor Q6581 and IC6581 output a low to pin 90. If the SC board becomes defective, a high is provided to pin 90. As a result, the unit shuts down and the power LED blinks 6
6 Blinks SOS: 6 blinks of the power LED may also be obtained from pin 3 of IC9003, the DRV_RESET input. The D board provides the 5V source needed to power the C boards. On the C2 board, the 5V is routed back to the D board via connector C20/C10, C11/D31 causing pin 3 of IC9003 to be high. If 5V is not routed back to the D board, pin 3 of IC9003 goes low. The set goes into shutdown mode and the power LED emits 6 blinks.
7 Blinks SOS: Pin 93 of the MPU IC9003 monitors the status of the SC, SU, SD board. During normal operation, the photo-coupler PC6480 outputs a low to pin 93. If the SC, SU, or SD board becomes defective, a high is provided to pin 93. As a result, the unit shuts down and the power LED blinks 7 times.
8 Blinks SOS: Pin 91 of the MPU IC9003 monitors the status of the SS board. During normal operation, pin 8 of connector SS23 outputs a low to pin 91. If the SS board becomes defective, a high is provided to pin 91. As a result, the unit shuts down and the power LED blinks 8 times.
10 Blinks SOS: The SUB5V and DT9V sources created on the A board are monitored by IC1100. If they are not present at pin 30 and 34, the MPU shuts down the unit. The power LED blinks 10 times.
10 Blinks SOS: The F_STB_15V of the P board, as well as the derived SUB5V and DT9V sources are monitored on the A board for excessive current. If a short circuit is developed in one of the supplied lines, pin 114 of IC1100 receives a high. The SUB5V and DT9V lines are also monitored for excessive voltage. When an over-voltage condition is detected, a high is also output to pin 114 of IC1100. The DT9V is provided to a DC/DC converter to create the BT30V for the tuner. If the BT30V becomes excessive, a high is output to pin 114 of IC1100. A high at pin 114 of IC1100 causes the unit to shutdown and the power LED to blink 10 times.
