More than 20 boards I have waited and changed same ic.....But last week only I was tried this way proud my self...but ur easily exposed .....but your videos are good ur way of teach wow nice ..keep it up
If you use a camera stand with flexi neck, your video presentation will be even better. The camera man is unable to hold the lens properly. However, your diagnosis and explanations are really good and helpful. Thanks for uploading
कितनी आसानी से अपने कर दिया सर क्योंकि मेरी भी कंप्यूटर में ऐसी प्रॉब्लम हुई थी डिस्प्ले नहीं आ रहा था मैंने कंप्यूटर शॉप वालों को दिखाइए पर उन्होंने देख लिया पर किसी को ठीक नहीं हुआ अंत में मुझे मदरबोर्ड बदलना पड़ गया 🙄
Please don't do that. The VRMs are designed to provide a variable voltage output according to the Vcc_VID code generated by CPU as per the load. There are more than 1 phase in VRM to reduce the switching load and ripple in the output. One phase means one or two Hi side MOSFETs, 2 Lo Side MOSFETs, one coil and some capacitors and a driver IC for the Hi and Lo sides. To reduce the load on PSU and to reduce ripples, each of the phases are switched on and off at different times. If you tie two phases to single gate driver output, both will switch at same time. Also the gate driver for the faulty phase is now totally out of the circuit, that means the voltage and current sensing if any done from that chip will be wrong or absent. This will cause erratic power delivery and may damage the CPU.
Also, since the CPU dynamically scales voltage and frequency, there will be voltage droop. The CPU will never get the correct reference voltage at all power stages due to the negative feedback loop that is used to correct voltage droop. This will cause the CPU to not run stable, similar to what happens when you run at high frequency and low voltage in case of overclocking. The diagnosis in this video was good, but the repair was totally unacceptable. It would have made more sense to swap parts from a donor or dead board since these LGA 775 boards are considered scrap by today's standards.
Pretty geeky . Can you help me . Cpu fan, chasis fan, turn on. But no signal to monitor, keyboard and mouse. Tried with a new ram, new SMPS, new CMOS battery. Clear CMOS also done. Took the motherboard out of the chasis. Connected just the processor , ram monitor, keyboard, mouse ( individually also) . But no signal to monitor keyboard and mouse . Ryzen 3 2200 g , on asus prime a320 motherboard. Please help .
Sir , If any similar problem occurs in future, I will not understand, which IC to connect to which IC gate. Did the jumper wire come over the motherboard ?
Jis mosfet se aapne jumper wire k through connect kia h... Wo mosfet and jis par kia h wo mosfet same output produce krte h... Aur agar ha to ic jo dono mosfet se connect hai wo over load se faulty ni hogi?
It would be appreciated if you could put close caption on this video. I have several dead boards that I would love to find out what is wrong with them but I cannot find a step by step video on how to trouble shoot and follow from the beginning in English motherboard repair. Does anyone know where you can get gigabyte schematics for their motherboards? I can't find any and when I thought I had found a site I got a virus. Thanks for any help.
Hamare city mein toh repair wale shorting hone par seedha poora motherboard hi change karne ki advice dete hai.. Aur apni mehnat bachate hai... Aur customer ko 2500-3000-3500-4000 rs tak ke motherboard laga k dete hai... Customer ka nuksaan karte hai... Voh bolte hai ki shorting ka koi illaaz nahi hai.. Aap board change karva lo

राजकुमारजी आपने इस वीडियो मे जो मदर बोर्ड लिया है. ऐसा ही मेरे कम्प्यूटर का बोर्ड है. कम्प्यूटर on नहीं होता है और display भी नहीं बनाता. और RST विभाग मे दिया हुआ led glow करता है. आप इस की वजह कृपया करके बताना
Mera computer 1-2 minutes ke liye display deta hai uske baad display chali jaati hai. Yadi turant use fir se on karo to bar bar on-off on-off hota rahta hai. Yadi thidi der rest ke baad on karo to fir 1-2 minutes ke liye display aata hai. Kya problem ho sakti hai.
