Part RJP30E2 IGBT replacement part

[tech2014]

I found 4 shorted parts on a YSUS board in a samsung plasma TV. I cannot find this part at digikey. Is there a replacement part I can use for this?

might be something here check specs first

Re: Part RJP30E2 IGBT replacement part

possibly, have you rebuilt this particular type of board before? what board is it?

Re: Part RJP30E2 IGBT replacement part

its for a YSUS board from a Samsung PN42C430A1D , Board part number LJ41-08592A, LJ92-01737

I have replaced IGBT in other board before but parts usually blow again after installation. The customer is a cheap skate and doesn't want to pay more then $100 to fix. I would rather order a new board but sometimes people are cheap and I don't want to turn away business. I read another thread where people were successful replacing the IGBT and tv worked after.

I actually have the FGPF4536 parts in my stock. Only problem is these parts are not insulated so I will have to find something to insulate.

Funny, this is the series I had in my mind where the ybuffer, y and x can be all suspect and the x is known to be an issue which can take out the y.

I tried replacing just the blown IGBTs on one of these and it was a fail in fact i think my tinkering killed the Y. end result was new y & X needed, buffer in this case was ok.

Then firmware upgrade. TV had a whole 1200hrs on it from memory.

Maybe the customer needs to be realistic. What happens if it goes bad? Who's footing the bill for the wasted parts and time spent?

anyway hope it does work out for you but there's a bunch of driver ICs and who knows what else under the board. that resin they put on is tough to get off to read the chips, that's what i found.

do you have a link to the successful repair as I'd be interested to read it.

Interesting , I was wondering if full plastic or not but datasheet says it is but then maybe there's other versions?

images of it show full plastic, ebay items also are FP.

can we get a pic of what you have?

Could use insulators.

Re: Part RJP30E2 IGBT replacement part

Its actually plastic, I was going by the pic shown on digikey, which is wrong. I actually replaced the IGBT and diode on the YSUS board and the TV powered up and no clicks. Before I added the XSUS to the circuit, I decided to check the IGBT on XSUS, good thing I did because I found 3 shorted parts on XSUS board. There are 2 RJH30E2 and one part number on part is 45G122. Is the RJH30E2 swappable with the FGPF4536 as well or not.

Does anyone know a part replacement for 45G122. I am only seeing these parts in China.

So ysus and xsus shorted is that the deal? I see this blowing. that's what i had and a straight IGBT replacement just blew all these bits.

What do oyou mean by powered up? vsus stayed up or not? unusual as any board disconnected will not let vsus stay up on these.

or do you mean you heard the startup melody?

would probably work but the H has a built in FRD, don't ask me how important that is probably for protection.

is the 45G122 shorted, do you have any other 45Gxxx Toshiba IGBTs around say from panasonic SC board repairs?

Re: Part RJP30E2 IGBT replacement part

I heard the startup melody and yes the 45G122 is shorted.

I can't remember now the layout but if the other 2 IGBTs are removed and this is shorted so be it.

I may have replaced it with a 45G128 I had but only because i was keen to have a go like you. Academic really because it all popped on me.

Re: Part RJP30E2 IGBT replacement part

Hi guys if been doing some testing on a 42 Samsung plasma that had the same problems,did some testing on the y subs and the x sus .on bothe boards the RJP30E2's are all pooched .all across gate collecter emitter are all short .. This don't make no sense at all .. Cheep design or what .there should be some other IGBT better then this to replac it with

Nothing wrong with the allocated parts or design--not 'cheep' as you put it--they are fine for the jobs they do.

Like ALL modern semiconductors this lead-free RoHS crap literally Wear Out!
--not much you can do about that--Except replace 'em!

Re: Part RJP30E2 IGBT replacement part

Ali I beg to differ, the parts that are failed get stressed badly in these especially when displaying white/bright screens. If Samsung would have added about 3 more of the same device in parallel or heatsunk them better these sets would last longer. These Tv's give a bad name to Plasma reliability wise image wise they are ok well when they work

Re: Part RJP30E2 IGBT replacement part

Nah--Probably the Timing in F/W causing thermal stresses/shoot-through/latency issues...
(Just like the Hideous Sams. D/E series sets, but less of an issue with these)

The Devices are well up to the job they are doing in that chassis if you consider their P-Diss and I/p. As I recall, they are paralleled two devices per 'side' of the bridge...
--They certainly get Hot--But no hotter than the old Panasonic PZ80 series said to be the most reliable plasma made--Now--They run HOT!...

Nah--I reckon--like the later series--F/W timing is the issue, which we cant alter as they didn't specifically issue one for this issue like they did for D/E series as far as I know...

They Are about 6-7 years old now--Very good by todays standard!

Re: Part RJP30E2 IGBT replacement part

Is it posible to replace them with FGPF4536 ?. The data shit seems puretty close ?

[ReeceyBurger123]

Re: Part RJP30E2 IGBT replacement part

Lol sorry but "data shit" haha made me laugh Also yes that would work. Maybe add a small fan over or under the heatsink to help them cool a little better ?

[Kokey]

Re: Part RJP30E2 IGBT replacement part

Lol pretty close

[Kokey]

Re: Part RJP30E2 IGBT replacement part

Yes shit lol 😂
