Is there a IGBT that would be suitable replacement for all 3 ? And if there is can you just replace the bad transistor/s or would you have to replace all as a set to match ? Thanks

hello.
I have two power amplifiers, both having their IGBT blown on the PSU.
The original mounted IGBT where marked with IRGB20B60PD1PbF and the gate driver is a IR2156STRPBF.
I looked at mouser and digikey and could not find any available IRGB20B60PD1PbF and somehow ended up using a Bourns BIDW20N60T.
I replaced the gate driver, the gate resistor and both IGBT. But as soon power is turned on, both IGBT shorts out completely (gate, emitter, collector) and the fuse on the AC line gets killed.
So I though i missed a capacitor or diode. I removed... -
Hi guys,
I have a LG Plasma that went bang one night.
Long story short, I took it to a "professional" shop to repair the YSUS board that was shorted and they did a half ass job.
I'm a long way down the path of teaching myself component level repair, but not 100% confident in everything yet, hence what might be a basic question.
The repair shop replaced 3 transistors on one of the two heat sinks and fixed one short, but the second set of transistors on the second sink still had a short.
So I removed this sink... -
taken from my thread about car alarm siren here: https://www.badcaps.net/forum/troubl...rm-siren-issue
there are 2 caps which im looking to get replacements for.
Branded as Gemcon
single 100uf 16v 6.5mm x 11.5mm
single 100uf 50v 8mm x 11.5mm
lead spacing is around 3mm
there is space for 16mm tall caps
rs components is good place for me to go since its close by, what replacements do you suggest and do these need to be low esr?
the caps have... -
Hello everyone, I have this ups/inverter IGBT 1450VA which was working great until it started showing short circuit on a small lcd screen, I opened it up and started troubleshooting it and indeed I found some fault transistors, I decided to get rid of all of the transistors next to the shorted ones and it worked for some minutes without a problem, but then I heard a relay tripping off, and now it is showing that 2 batteries connected in series have no power at all, and if i disconnect the 24dc in then the battery are showing they are full (28vdc) with another inverter, they are working great no...

I found my old Xbox 360 in storage and opened it up to see if there was anything that broke since it was built in 2006 (launch era Xenon revision, never red ringed, never been serviced) and didn't want to find out by releasing magic smoke. Upon moving the dust bunnies out of the way I was greeted by a bunch of capacitors with crud coming out of the top; it doesn't seem to have leaked onto the board so at least I have that going for me.
I'm posting here because I want to try to source replacement caps myself from Mouser or Digikey instead of braving eBay or waiting for places to have...
