Re: Philips 715G8991-C01-000-004Y
Hello. The manual shows that the Current Sense Resistor that is blown at the photo is 0.2R or 200mOhms. The colour code though tells me that this resistor is 0,22 Ohms with 5% tolerance. Do you know how many watts this resistor is and what type? Thanks!Comment

R9101 is likely a 0.22Ω 2 watt, the blue ceramic cap (C9108?) is also blown, so ic9101 will also be damaged and need replacing. R9109, R9106, R9104 are also damaged, D9102 is also likely bad, and I would also replace C9107 and C9112Last edited by R_J; 07-28-2023, 11:51 AM.Comment

Hi
I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.
1. FR950 - blown fusible resistor - 0.2 Ohm 1W
2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
3. R835 - Blown Resistor - 20KOhm SMD resistor
4. D930 - Shorted Schottkey Diode... -
Hello.
Some components have exploded and I can't figure out the values. I have obtained the manual for this power supply for 65" but comparing components there are some differences and it is not reliable.
Could someone leave me the power supply manual for this 55" model?
I would be very grateful03-19-2024, 01:19 PM -
Hi to all forum members,
Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.
Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor... -
I am curious if a 0402 resistor could go from 43 ohm to 0. In electronics class and my experience a resistor can degrade and gain resistance all the way up to not being able to conduct at all. I have never heard of a resistor decreasing in resistance and becoming 0 ohm or a dead short… that's not the direction they fail… or so I thought.
I was attempting to remove a wson8 chip on an iMac motherboard and it required a lot of heat, on one side of the chip were 3 0402 resistors that were very close. I popped the chip out unintentionally out of the tweezers and sent those resistors... -
The resistor on this waterpik blew. I changed it with the a similar spec 47ohm 2 watt yageo resistor but it still keeps blowing the resistor. Checking with the multimeter the motor, capacitor, diodes, and thermal fuse all checked normal. Will a higher ohm resistor work better? What ohm resistor will work better to repair this waterpik? This video is showing the repair with a 56 ohm resistor https://www.youtube.com/watch?v=_J7_rV7ui1Y
