Is it really my problem that I do not speek Spanish / Chinese / Indonesian / whatever?

Lately there have been a few cases of customers accusing me of being rude or flat out stealing out of them.

The thing is, they do not speak English (and of course they do not read it) and any attempt to communicate to them that what they bought is not what they thought they were buying, but was what it SAID it was (in English) or any attempt to tell them that I can not understand what are they saying is, well, doomed as they do not speak English.

As you can see below one of them actually told me I *must* learn Spanish because there are 80 million Spanish speakers in USA.

Of course, considering he's the one with a problem in the first place it seems to me he should learn English although, in all fairness, I also see enough native English speakers who also buy based on what they *think* rather than what the listing says.

So perhaps it's even more important to learn to pay attention to what you are actually buying and applying common sense than learning another language.

And yet there are at least 200 million English speakers here in US and a recent study found the Hispanic children to be the largest poverty group in USA, ergo the least educated one.

So it seems to me the solution is to have everyone speak at least the official language of this country before they start accusing others. Maybe not perfectly - I myself am not a native English speaker either - but at least enough so you can communicate in the official language of the country.

If you can't then you should only blame yourself.

From where I stand I'd readily lose 80 million illiterate customers.

What do you think?

Dear huongdao2010,

I am sorry, I do not understand your English.

But from the little I understand it seems to me you have a bad buffer board.

If either of those ICs were defective you would not have gotten half an image.

When 6871QYH039B fails, should buffers be replaced too? (same for 6871QYH039A, 6871QYH039B)

Question:

Hi. My concern is should I go ahead and get the Y-buffers too. Cant a bad buffer blow the new Y-sus? How can I check the buffers without replacing the Y-sus? Do you carry the buffers? Thanks, Geo.




Answer:
With this particular YSUS, an in fact with most sustain boards made by LG (at least in the 2004-2007 models) I would not worry about the buffers when a YSUS fails for several reasons:
 
First, the popular concept that when YSUS fails one should look for the buffers is most likely coming from the Samsung designs from the same time period. LG electrical design is similar and does not have the same failure characteristics as the Samsung boards.
In the Samsung cases it's the buffer board that fails first and damages the YSUS.

With LG, the sustain actually fails before the buffer and usually does not affect it.
Second, when the LG buffer ultimately fails (because that can happen too) it does not tend to damage the sustain. It is possible for it to happen, but it is rare.
 
Instead, when an LG plasma buffer board fails (e.g. in Toshiba 42HP66 or  50HP66) it will typically cause a vertical line as explained in this previous article.

As with any failure it is not guaranteed that it will happen that way. It's just the most common result.
 
So, in a nutshell, it's not worth worrying about the buffers at the time when you know the problem is in the sustain.
It's not bad to check them, but it would be unusual for them to have failed at the same time with the YSUS.

LG 42PC5D YSUS EBR36954501 EBR39214401 question

Question: 
I am trying to fix an LG 42PC5D, no picture, does not pre-warm up the screen, the fuse on the YSUS board FS5 1.5 amp is blown, it blew again after replacing, it is connected to the STEP-UP/FLYBACK SWITCHING REGULATOR on the board, I don't have a schematic and working on plasma is new, without tracing the circuit board traces, is this something this driver chip would fix this problem?



Answer:

It might or might not, I can't promise.

That fuse doesn't usually burn when the IPM fails. It is not impossible for it to happen, of course, but if I were you I'd search where the high current to blow the fuse is coming from.

It may or may not be the IPM.
