Celebrating 10,000 happy customers on record

We reached a 10,000 positive reviews on eBay milestone today:



We have many more than, of course, just like anyone on eBay where feedback ratio varies anywhere between 1:3 to 1:20 depending on your niche market, follow-up procedures, volume and what not.

We also have seen companies come after us and reach that milestone way faster than us.
And that's OK.

We also have those (at the moment) 1.5% bad reviews of people who thought we were scammers, rip-offs etc - I've covered a few of those in previous topics already.

Yet 10,000 public, independent positive reviews from all over the world, accumulated in the course of 10 or so years of operation are a clear vote of confidence and confirmation that we are getting something right.

To us it is more than that, though.

It is a proof that the world is still reasonable and sane, with people facing and resolving problems through communication and mutual work and not blames.

Thanks to everyone who was part of that process!

Repairing LG 60PB5600-UA 60PB6650-UA no image problem - bad EBR77186101 only hint

Just posted a video yesterday discussing a unique manifestation of otherwise common problem we've seen and documented in LG buffer board EBR77186101 found in LG 60PB5600-UA, LG 60PB6650-UA and possibly others:


Presently we do test and service the buffer boards through the LG YSUS board EBR77185601 repair service listing or through the whole LG EBR77185601 / EBR77186101 / EBR77186201 trio exchange service.


Only the capacitor that tends to go bad was bad; the other two were not.

Also, the other two have different values, even though they are in parallel; must be because they are designed to suppress different harmonics.

Also, just a reminder that this is the first time we've seen ONLY the buffer board fail; 99% of the time we've seen a problem with those sets it's because of a failed YSUS board.

Note the capacitor from the buffer is now included in the repair kit for YSUS EBR77185601 .

LG 55LX6500 / LG 55LX9500 main board repair services now offered

We've launched a number of LG main board repair services over the past month and I thought I'd use the blog to update web crawlers and anyone else who cares:

LG 55LX6500 main board repair service:
http://www.coppelltvrepair.com/p/1612/ebu60962901-ebr69488901-main-board-repair-service-from-lg-55lx6500-ub-led-tv

LG 55LX9500 main board repair service:
http://www.coppelltvrepair.com/p/1614/ebr60963101-main-board-repair-service-from-lg-55lx9500-ua-led-tv

The most common issue for those boards is coming from the main processor, which is an LG branded and enhanced version of the 3549 multimedia processor platform found in many TVs from same time frame , but enhanced with LG proprietary stuff, so no regular 3549 can be used in place of the LGE3549XS or LGE3549XSP  ICs.

The issue is not with the chip itself, actually, but with the BGA underneath it, which corrodes and gets detached eventually.

One problem with those boards that was stopping us in the past - and is still a concern for everyone working with them - is that they PCB itself is very tiny and prone to warping under heat.

Now we have a high-end automatic professional  BGA rework station - can be seen in some of our videos - which allow for much more precision and reliable operations than before.

As such, it allows us to provide repair services we didn't dare to offer before and at a cost that is actually lower than what we would have done before.

If you want to know if we offer repair for a particular board, just search for it at www.coppelltvrepair.com !

Condemnation and praise for Coppell TV Repair LLC in one day

A significant and quite unpleasant part of my job is to talk to upset customers.

Today I spent well over an hour exchanging pleasantries with an eBay customer who refused to accept the fact that eBay refers to every repair service listing as an "item" and shows, without vendors being able to control that, the words "Items available" on the page.

I learned, along the way, that my use of English language is bad, that our offer is fishy and that my statements are contradicting, so beware - what I say may or may not be correct and if it sounds fishy it might indeed be!

Oddly enough, eBay sided with our version of the story this time and rejected customer's claims, so we had to take care of his issue manually after he learned from another source he was wrong...which we did, of course.

Just for the record, here's part of the exchange, before it got messy:



 The reason I am making this post in the middle of a fairly busy Monday is because literally half an hour after we were done with that customer (hardly winning his heart, but being fair nonetheless and not making any money of him!) I received another feedback, from another customer and it looked like this:


Much shorter and easier to process, wasn't it?

What I find ironic is not the mere coincidence that we received condemnation and praise in one day.

That is not uncommon.

What I find ironic is that both customers have no feedback on eBay, which makes it logical that both of them are brand new there and have not had past experience dealing with eBay and repair services.

The first customer accused us in misleading him and making false representation of a repair service due to the term "Items available" placed on the page by eBay (not us!); he also accused us to be profiting from misleading people like him.

The second customer, who used practically identical repair service offer, apparently had no such issues and is now apparently happily enjoying his or her TV at a faction of the cost of a new one.

Where do you think the difference in their experiences comes from?

If it was up to you which customer would you rather be - the ones who sees problems everywhere, but not in himself or the one that reads offer descriptions and follows instructions?

It isn't black and white, I know, and I do not ask anyone to trust us blindly.

yet the public fact is that roughly 98% of our customers on eBay find us of value.

That must mean something, right?

How to test LJ44-00144A / PS-506-PH Samsung power supply on the bench

Just made a video for a customer how to bench test the power supply LJ44-00144A used in Philips 50PFP5332D/37.

The board was returned from repair and thought I'd post it in the blog as well as we often search here for videos we've made before:


As noted in the video this is not a 100% reliable test in regards to the board's functionality.

But it is easy to do, fairly helpful when it comes down to isolating a problem and, for the most part, fairly reliable.

Related repair service(s) for the board:
