Hi, I have a Yamaha RX-497 receiver, and one day I came home to a burnt smell and the breaker was tripped. Upon opening the receiver, I saw extreme damage to the main power board. C254 was exploded, R261 was burnt, D255 was shorted, Q254 is open circuit, D261 (bridge rectifier) is also open, traces to IC252 (TC4013BP) are vaporized right off the board. Not sure about any other damage, I'll have to desolder the flip flop to test it. Also the transformer T251 is getting hot when plugged in. What could have caused such extreme damage just sitting plugged in? Only repair that was done in the past...04-18-2024, 05:54 PM

I bought 2 of these supplies off of Temu , it said they were original for Samsung phones and I bought them cheap so I thought I got a bargain. Looked inside and they are definitely not original. Could you provide any pointers about safety, other characteristics etc. I cannot identify components 5433q 349DJB (what is that?) and it seems it has normal resistor instead of fusible resistor. Is it a fire risk. Lots of questions. Thanks for any time spent on this..Today, 12:56 AM

For those in 220V locales, anyone power their SMPS with DC, and how high of a voltage is okay?
What kind of PSU?
I suspect that 240V * sqrt(2) = 340V DC is probably fine because that would be about how much the the primary rectifier ends up with peak voltage. Just wondering, other than input capacitor voltages, can one go up above this 340V without damage? Will that input capacitor be the upper bound?
Wondering if exactly that, can I feed near 400VDC into bona fide specced at 220V SMPS without damage?
Currently have a 120/220V switchable SMPS I want to see if I...Yesterday, 08:03 PM -
Hi as you can see from title, I have a samsung tv here that will show the smart tv logo and then no picture after that even hitting input or menu on remote and shows nothing but the backlight still appears to be on. The tv will turn itself off after a minute or so automatically. I'm somewhat confused if this is either a eeprom problem or a bad led strip problem. The power supply makes a pretty noticeable humming sound when it's turned on leading me to believe one of the leds are shorted but idk honestly. Any of you guys have any help for me? I have a good multi meter and can take pictures of whatever...04-13-2024, 10:05 PM

I would like some help and advice which will be much appreciated, I am looking at a mac Macbook Pro A1990 board 820-01814-A. When I connect the USBC meter via external Power Supply I see Power cycling between 5v.040 A to .468A then it repeats.
After doing some diode tests I get a complete Short on L9530 which is the output inductor for PP1V8_ssd1.
I have given the screenshot here, I would like your recommendation and advice if anything I need to test get this issue sorted Or is it SSD short , Your help on this will be much appreciated...04-20-2024, 11:41 PM

Hi people, i have an acer nitro 5 with motherboard model gh51m la-k861p , it came with the resistor pr103 blow up, i repaced that resistor, i check the coils plb2, pl301, pl501 and has no short to ground, i conect the charger and it doesnt power at all, i check pqb3 on pin 5 to 8 and its 19v, pin 1 to 4 its 0
so i repaced, pqb3, pqb4, and makes no change, still no acdrv, i replaced bq24781 and makes no change, still no acdrv, if someone can help pls, thanks, this are the schematic and boardview

So I'm having difficulty finding line drawings for this motherboard NM-C53. My charging port was broken. So I replaced it with a terrible solder job. Problem is pin 3 on the drawing I saw on here has it listed as adapter-id. Now I checked my other pins and I have continuity (resistance check from power to ground). Pin 3 shows nothing. Now I boot the computer and it says to use a power adapter with the proper wattage and won't charge. I have read that pin 3 is usually tied to a resistor that identifies the charging power thus disabled the ability to charge if it fails the check. I look at my board...Yesterday, 07:27 AM

Hi.
My Hp G6 laptop died while using it.
I opened it up and used a thermal camera on it to see if anything was getting hot. The RT9513 chip (EQ ED B1Y) which is supposedly a battery charger ic was getting hot. I ordered a new one and replaced it but its still red hot. Where should I look next?04-20-2024, 10:02 AM -
