Can I interchange a 20 pin wire to 16 to 14?


You need the correct board when ordering replacements you need to quote all the numbers on the original often on a separate sticker on the board as there are often many versions with same board number

Sony KDL40EX500 power supply. Board has standby power but other voltages don't come up. Tried shorting "Power On" pin (pin 13) to "STDBY3.3V (pin 15) to try and get the board to power up but nothing.


If You do not see any open link or resistor, short IC or transistor on power supply it must be a control board problem. You must get the set to SONY, as it is necessary to exchange board and upgrade software.

I cant find where do i connect power switch there no slot indecated on the board help me pls.


Hello Friends,
If you are ask mother board power option. There are two power option every mother board, one option is SMPS power and sec option is Power Jumper. SMPS two power socket indicate 24 Pin and 4 pin also same option 24 pin and 4 pin socket available in mother board. Second option is 9 pin jumper socket hear connect to HDD power, reset power, cabinet power, power LED, and +5v DC. So you open PC and see all section and solved you problem.

Thanks.

How do I replace a power supply on a Compaq Presario SR5110NX Desktop PC


you can purchase a power supply from any computer store *********** board supports both standard IDE and Serial ATA connections, so you want a power supply that does SATA power as well. Unplug the power cord from the back of the computer. remove the cover from the case and verify that there is no green LED on the board that is lit up (if there is, there is still power on the board). unplug all connections from the current power supply, including all drive power and the large 24pin plug (actually a 4 pin plug that is combined with a 20 pin plug) on the board, then unplug the 4 pin plug near the processor. careful that the 24 pin plug and the additional 4 pin plug near the processor have latches on the side. Remove the 4 screws that hold the power supply in and remove the power supply, install new supply and reinstall the 4 screws. first plug in the 4 pin plug that connects with the 20 pin, the 4 pin plug has no latch, it is held in place by the 20 pin plug. then plug in the 20 pin plug and the 4 pin next to the processor. then plug in the drive power to all of the drives. Install the power plug at the back of the system and you should see a green LED on the board when you insert the power. replace the cover and power the system up.

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.
