Re: Haier 42EP24S plasma

well don't know whats in the kit...
sounds like nothing a new TV wouldn't fix the problem
(yeah I know bad joke...seems for the money they ask for these things they should come with 10 years free repair regardless of fault)

found this post on what the kit consists of but I really have no idea

Haier-42EP24S-42-in-EDTV-Ready-Plasma-Television

Haier company did make a, what they call, 'Upgrade Kit' (TV-3940-01) to permanently repair the television and keep it that way. The Kit consists of the following:
Control Board
TV-5210-39, Y-SUS
TV-5210-35, Z-SUSj
TV-5210-37,
New EPROM Chip 2006 version TV-2455-03,
Upgrade Label TV-4050-08
Haier Service Bulletin SB-TV-0003 containing the instructions to replace the boards yourself. Really isn't very hard. All you need is one tool, a screwdriver

it was a personal ad so I just posted in the relevant bit.

found this from gonzo's link on the upgrade code

HTH

I will like to know with part is the damage one .I dont think that all of the parts are damaged.i have some pictures so you guys can observe and tell me wich one i should replace.

Re: Haier 42EP24S plasma

Wow... they actually used decent caps in the power supply. Dunno about the other boards though, can't really tell what they are.

Re: Haier 42EP24S plasma

R207 looks like its had a hole blown in the side of it, which if so would indicate a PSU fault. Other than that its imposable to tell from just photos.

Re: Haier 42EP24S plasma

I have absolutely no idea on this TV so the below is just my observations on the situation.

You would need a tech who actually know what the actual damage was that was done
it sounds like it might be common mode of failure if they made a kit for it.

you have with this also,
some faults may have the same root cause but its possible the damaged components might not be the same.

so you would have to hope that it causes the same component to fail to do a blind replacement of parts.

Unfortunately since they are doing it as PCB replacements
(which is the way a lot of things tend to be done repair wise these days (Sadly) )

As Harvey said from photos you just cant tell,
depending on the fault (or possibly faults here)

A component can fail and LOOK fine

Without Electronics knowledge and skills in trouble shooting
your best bet is the PCB kit (probably refurbished PCBs)

Sometimes things are just lemons and come out with faults unknown to the manufacture at the time

Since the kit mention a possible service note there could be a few component circuit changes on the PCB.

not that I am any guru on PCB manufacture
but the PSU doesn't look to be a crap built unit.

Please bear in mind were R 207 is in an area that you can consider as "deadly" as your house wiring
(some respects more so)
That cap is a 450V

I cropped and turned the image on it side and double the size



it looks like it to me too but that not to say it is only testing will for sure decided this
This could only be the start of your problems, you could have dead mosfet(s) and maybe that resistor saved it from burning up but its still faulty I don't know.

If you did managed to repair it "as it is now" there is obviously the danger that it will happen again anyway
This appears to be why the kit was release to solve the issue (or issues)
once and for all

it sounds to me like a PSU problem but from the kit things must run deeper then that only.

But then again I don't really know what involved in the kit

It sounds to me like you trying to save a few bucks by going to component level and there is nothing wrong with that idea
but you really need to know what you doing when you go to that level.

Without know exactly what needs to be done you might be better if you want to get it up and running buy a kit to repair it

Good luck

Re: Haier 42EP24S plasma

Your most probably faulty part is the hybrid IC on the ZSUS board. At least for similar TV`s this is the most common problem.
You can check this out by doing a continuity measurement between GND and SUS_Out or VS and SUS_Out. The associated pins should be labeled on the board.
You can check the fuse on the ZSUS board prior to this, if it is blown you may have an short at the 180v rail, either caused by the hybrid VR or by another component.

Sadly, the needed replacement parts don`t make it into most western countries.
Any way, this topic:

http://forum.iwenzo.de/reparatur-fla...82dbe89968fed1


in a German forum explains the basic schematic of a similar hybrid and how to rebuild it with more common components.
It was original for an YSUS board, but the hybrids are may be not that different.
At least the schematics should easily be understandable for any non German speaking people.

Re: Haier 42EP24S plasma

EDIT:
The YSUS board is similarly build, it could may be the cause for your problems too.
All what is said about the ZSUS board is applicable to the ySUS board too.
