आज में आपको पोसà¥à¤Ÿ कारà¥à¤¡ को कैसे इसà¥à¤¤à¥‡à¤®à¤¾à¤² किया जाता है और उस पर पà¥à¤°à¤¦à¤°à¥à¤¶à¤¿à¤¤ होने वाले कोड से Motherboard की Testing कैसे करेंगे ? के बारे में बताऊंगा।
सबसे पहले पोसà¥à¤Ÿ कारà¥à¤¡ को मदरबोरà¥à¤¡ के पीसीआई सà¥à¤²à¥‰à¤Ÿ पर लगाते है। अब मदरबोरà¥à¤¡ को पावर देकर ओन करते है। सबसे पहले पोसà¥à¤Ÿ कारà¥à¤¡ पर आपको सà¤à¥€ LED लाइट की सà¥à¤¥à¤¿à¤¤à¤¿ को निचे लिखे तरीके से जाà¤à¤š करनी है। की सà¤à¥€ Volts और Signals सही आ रहे है की नहीं।
How To Check Motherboard Using Diagnostic Card Easy Manual in Hindi
Debug Card INDICATORS
CLK यह LED ओन है तो इसका मतलब बोरà¥à¤¡ में Clock Signal आ रहे है। यदि या off रहता है तो कà¥à¤²à¥‰à¤• सरà¥à¤•िट काम नहीं कर रहा है। यह सिगà¥à¤¨à¤² यदि CPU Socket में पà¥à¤°à¥‹à¤¸à¥‡à¤¸à¤° नहीं लगा है तब à¤à¥€ आà¤à¤—ा। BIOS जब पà¥à¤°à¥‹à¤¸à¥‡à¤¸à¤° बायोस को रीड करता है तो यह लेड ओन रहती है यदि यह लाइट मदरबोरà¥à¤¡ ओन करने पर à¤à¥€ नहीं जलती है तो मदरबोरà¥à¤¡ में बायोस, रैम या पà¥à¤°à¥‹à¤¸à¥‡à¤¸à¤° ख़राब हो सकते है। IRDY डिवाइस रेडी सिगà¥à¤¨à¤² मिलने पर यह ओन होती है। FRAME PCI Bus Frame. सामानà¥à¤¯ परिसà¥à¤¥à¤¿à¤¤à¤¿à¤¯à¥‹à¤‚ में इस लाइट को ओन होना चाहिà¤à¥¤ इससे à¤à¤• PCI फ़à¥à¤°à¥‡à¤® संकेत का पता चला है।RST Reset यह लाइट जैसे ही मदरबोरà¥à¤¡ को ओन करते है तो आधे सेकंड तक ओन रहती है फिर ऑफ हो जाती है यदि यह लगातार ओन रहती है तो रिसेट सिगà¥à¤¨à¤² सही नहीं है या बिलकà¥à¤² à¤à¥€ नहीं आ रहा है। 12V Power Supply, इस LED के ओन रहने पर यह पता चलता है की बोरà¥à¤¡ को 12v की सपà¥à¤²à¤¾à¤ˆ मिल रही है। यदि 12v की सपà¥à¤²à¤¾à¤ˆ नहीं आ रही है तो यह ऑफ रहती है। -12V Power Supply, इस LED के ओन रहने पर यह पता चलता है की बोरà¥à¤¡ को -12v की सपà¥à¤²à¤¾à¤ˆ मिल रही है। यदि -12v की सपà¥à¤²à¤¾à¤ˆ नहीं आ रही है तो यह ऑफ रहती है।5V Power Supply, इस LED के ओन रहने पर यह पता चलता है की बोरà¥à¤¡ को 5v की सपà¥à¤²à¤¾à¤ˆ मिल रही है। यदि 5v की सपà¥à¤²à¤¾à¤ˆ नहीं आ रही है तो यह ऑफ रहती है।-5V Power Supply, इस LED के ओन रहने पर यह पता चलता है की बोरà¥à¤¡ को -5v की सपà¥à¤²à¤¾à¤ˆ मिल रही है। यदि -5v की सपà¥à¤²à¤¾à¤ˆ नहीं आ रही है तो यह ऑफ रहती है।3V3 कà¥à¤› motherboards के PCI सà¥à¤²à¥‰à¤Ÿà¥à¤¸ में 3.3V बिजली की आपूरà¥à¤¤à¤¿ आती है। यह à¤à¤²à¤ˆà¤¡à¥€ मदरबोरà¥à¤¡ में 3.3V आपूरà¥à¤¤à¤¿ की सूचक होती है। अगर सà¤à¥€ à¤à¤²à¤ˆà¤¡à¥€ लाइट सही सà¥à¤¥à¤¿à¤¤à¤¿ में है तो उसके बाद कारà¥à¤¡ के डिसà¥à¤ªà¥à¤²à¥‡ पर आये पोसà¥à¤Ÿ कोड को देखेंगे।

Award BIOS
Error code: 00 (FF)
Code Meaning → यदि यह कोड आता है तो मदरबोरà¥à¤¡ में Post Self Test सही नहीं हो रहा है।
Solution → इस कोड के आने पर मदरबोरà¥à¤¡ या तो पà¥à¤°à¥‹à¤¸à¥‡à¤¸à¤° ख़राब है या फिर पà¥à¤°à¥‹à¤¸à¥‡à¤¸à¤° को सही सपà¥à¤²à¤¾à¤ˆ नहीं मिल रही है। इसके लिठसीपीयू को दà¥à¤¬à¤¾à¤°à¤¾ या दूसरा लगाये। और कोर वालà¥à¤Ÿ को सही होने के लिठचेक करे। यदि सब ठीक है तो बायोस ख़राब हो सकता है बायोस को दà¥à¤¬à¤¾à¤°à¤¾ पà¥à¤°à¥‹à¤—à¥à¤°à¤¾à¤® करे।
Error Code: 01
Code meaning: इस कोड का मतलब है की Processor Test के दौरान समसà¥à¤¯à¤¾ है।
Solution → यदि कोड इस कोड पर रà¥à¤• जाता है तो पà¥à¤°à¥‹à¤¸à¥‡à¤¸à¤° से समà¥à¤¬à¤§à¤¿à¤¤ सà¤à¥€ कॉमà¥à¤ªà¥‹à¤¨à¥‡à¤¨à¥à¤Ÿ की जाà¤à¤š करे। जैसे पà¥à¤°à¥‹à¤¸à¥‡à¤¸à¤° वोलà¥à¤Ÿà¥‡à¤œ, फà¥à¤°à¥€à¤•à¥à¤µà¥‡à¤‚सी, सीपीयू ओवरलॉकिंग पर FSB । बायोस को जमà¥à¤ªà¤° के दà¥à¤µà¤¾à¤°à¤¾ रिसेट करे। यदि सब ठीक है तो पà¥à¤°à¥‹à¤¸à¥‡à¤¸à¤° ख़राब है इसको बदल दे।
Error code: C1 to C5
Code meaning: यह कोड आने पर memory self-test से समà¥à¤¬à¤‚धित समसà¥à¤¯à¤¾ होती है।
Solution → यह कोड तब आता है जब रैम सही से काम नहीं करती है। जà¥à¤¯à¤¾à¤¦à¤¾à¤¤à¤° à¤à¤¡à¥à¤°à¥‡à¤¸ सिगà¥à¤¨à¤² के सही न मिलने पर इस कोड पर आकर रà¥à¤• जाता है। इसके लिठरैम के पिनों और रैम सà¥à¤²à¥‰à¤Ÿ को अचà¥à¤›à¥‡ से साफ़ कर दà¥à¤¬à¤¾à¤°à¤¾ रैम को लगाये। (रैम के पिनों को पेंसिल मिटाने वाले रबर से साफ़ करे ) या रैम को बदलकर दूसरी लगाये। कà¤à¥€ कà¤à¥€ बायोस के ख़राब होने पर à¤à¥€ यह समसà¥à¤¯à¤¾ आती है।
Error code: 0D
Code Meaning: अगर video channel टेसà¥à¤Ÿà¤¿à¤‚ग को पास नहीं करता है तो यह कोड आता है।
solution → यह कोड आने पर graphics Card को साफ़ कर के लगाà¤à¤‚ या बदल दे।

4.By the way check -USBOC_R (Rear) LR7 --normal
System Management Bus causes CPU No Work(P5KPL-VM)-Mainboard repair
1.System Management Bus carrying SMBCLK & SMBDATA.
2.One of this two signals lost could cause CPU stop .
3.IF PCI IRDY Wave show aboved not communicating with CPU, check those two singnals.
P5P43TD PRO Shut-down at 0.5 Second -Mainboard repair
1.Shut-down at 0.5 Second .
2.Check W83627DHG-A Pin71 O_PWROK SIGNAL
3.Low Impedance ,change IO WORK
GA-945PL-S3 IO affect DDR18V Voltage -Mainboard repair
1.GA-945PL-S3 DDR18V only +1.3V
2.Check DDR18V_OV1~3 Signals from IT8718F-S
3.Bad IO ,change OK
3VSBSW# signal affect FSB-VTT(P5G41-M) -Mainboard repair
In this P5G41-M
1. O_3VSBSW# come from IO (W83627DHG-A) Pin 91
usually S0 enter S3 state, this signal pull down to 0 to cut Major voltage supply.
So normal operation it is +3V.
2.In this case,resistor arrays defective causes P_5V_DUAL_M_# signal not been pull down to 0.
3. The high voltage level P_5V_DUAL_M_# pull down +1
.2V_reference to ground,
LM324 could not produce +1.2V (FSB-VTT)
GA-EP43-DS3L 2seconds & 12seconds reboot experiment -Mainboard repair
The new board characteristic
1.take off DDR2...... C100 00C1 12 seconds Reboot
2.short Cpu HD51# & HD55# Signals .....2 seconds Reboot
MS-7267 Can't power on due to CLR_CMOS and SLP_S3# signal fail ----motherboard repair----
Because CLR_CMOS jumper short and SLP_S3#(ICH7 F71882FG MS-7G) signal fail.
So the board can't power on.
KBPWR jumper erosion cause C7C6 C7C5 (P4P800 SE) -mainboard repair
1.KBPWR jumper supplies +5V and +5VSB .
2.If IO can't detect the pull up voltage(for kb ms signals ) 5V then pause at C7 code.
P5KR W83627DHG-A defective causes shut-down immediately - mainboard repair
In this board not like usual one ,the S_SLPS3# is not switching. While plug-in ATX the signal always holds on +3.3V ,so we pull up the pin 73 of IO(W83627DHG-A) to see its condition.
NF-6150LE-N-A2 Build in VGA fault signal VSYNC_5V compare (MS-7298) -Mainboard repair
1.Build in VGA Fault.
2. Compare abnormal & normal signal -VSYNC_5V
3. NF-6150LE-N-A2 malfunction.
4.Reball useless , change OK.
504F +BAT_3V OL(open line) (M2A-VM) -Mainboard repair
1.SB600 +IT8716F-S characteristic.
2. +BAT_3V signal to IT8716F-S Pin69.
3.Open line causes SB600 hang on code 504F.
Power Lost After 1 second -Means Main voltage Not ready( Vcore +1.2V VDDA +1.8V......)
Power Lost After 4 second -Means power up procedure executing error (signals error cold solder joint)
EXPERIMENT:
1.TAKE OFF CPU: do not power lost due to power up procedure not yet implemented.
KBPWR jumper erosion cause C7C6 C7C5 (P4P800 SE) -mainboard repair
1.KBPWR jumper supplies +5V and +5VSB .
2.If IO can't detect the pull up voltage(for kb ms signals ) 5V then pause at C7 code.
1.reset signal ---square wave
2.bios CS# SO CLK measure
In this case ,bios data error send a wrong signal to SB.
If you dismantle bios , the reset signal regain
1.Debug code -3837.
2.Hang on Logo.
3.Hang on USB Initializing.
4.ICH7 (NH82801GB) defective -reball or rebga are useless.
5. change ICH7 OK.
The new board characteristic
1.take off DDR2...... C100 00C1 12 seconds Reboot
2.short Cpu HD51# & HD55# Signals .....2 seconds Reboot
1.Shut-down at 0.5 Second .
2.Check W83627DHG-A Pin71 O_PWROK SIGNAL
3.Low Impedance ,change IO WORK
1.SB600 +IT8716F-S characteristic.
2. +BAT_3V signal to IT8716F-S Pin69.
3.Open line causes SB600 hang on code 504F.
