Have a look at this photo, pretty clear.http://www.shopjimmy.com/vizio-080gl...-led-board.htm -

The resistor probably went short and gave too much voltage to the cap, causing it to pop, and then short, and when it went short, it blew the fuse.Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.
My computer doubles as a space heater.

It is the high Voltage snubber ceramic cap for the PFC MOSFET, it is connected between the S and D pin of the MOSFET, ceramic cap fail's mode is shorted circuit., common failure in other power supply boards too.
Best to go with higher Voltage than 1KV.Never stop learning

Repair manual part number 702_58300000148618_ara_en_a
It took way too much effort to find this manual so I am sharing it here so the next person can find it easily. Also, I am mad at Bosch for not publishing it on their website, so they deserve to have it leaked....07-14-2025, 07:36 PM -
Hi Dear Friend., I am working on a Apple MacBook Pro A2338 820-02773-A. The history was that the AON Rail on the Trackpad connector JT400 was burnt. After I removed the burnt connector, I tested with the meter & no shorts. Connected the USB C power & all booted fine, no problems at all. I soldered a New TP connector put in the old trackpad with a brand new Flex cable. The laptop beeped in the start but no display. I removed the connector & the display was fine again. USED a known good Trackpad & a Flex cable, even with this still the same problem. I checked the connector whether... -
I picked up this used Bose Acoustimass 10 IV speaker system. Speakers seem to work fine, but the subwoofer does not make any noise. So I took apart the unit and found some obviously failed (burnt) components:
- 1x 3.14 A @ 250V main circuit fuse
- 1x bridge rectifier GBU601. there's actually two of these on the board, one is obviously burnt and the other does not seem to have any anomalies like shorts. However I figure may as well replace both.
- 2x diode. This is tricky because the only markings I see on it are: "617 402". No current rating or anything else.... -

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
