Probably "man yong", which means literally "10,000 use(s)".

Prices IIRC are about 12-18 USD per chassis, with the lower figure for simple 19-21" (they actually list them by mm) chassis. The chassis come with remotes and batteries! Here's one aftermarket company offering them, albeit these are Sharp chassis:

http://www.lasertec.com.mx/chasis/chasis_universal.html

Funny thing is, you can't readily identify the parts on them. One Chinese chassis has a HOT that reads HY109-19 - nope, it ain't Hyundai. No logo, either. Fix it? I think not...

The same magazines offer portable CD players for about 5 USD in 2K+ quantities. Name your brand and they'll imprint it, adding about 18 cents per CD player.

Cheers
It says those lasertec chassis' are made in Japan. I highly doubt that.

1) It's a special building block style TV chassis for the repair market

2) All of the parts are connected with the cables,it's very convenient to change and repair

Heres a brand new modular Chassis:

Whats the point of a modular chassis if you cant buy new modules?

Isn't it funny? We're a capatilist country, yet many of our business's are setting up shop in China, a hybrid communist country. They're setting up there because the cost of parts and labor is cheaper. Our country can't match that low cost without sacrificing wages and worker safety. China's labor laws aren't as strict.

Economics makes some strange bedfellows and contridictions...

Reading through trade magazines from the fifties you can see ads for companies that sold used tv chassis in bulk and grade 'B' picture tubes (or were they lower than that?) which were just dusted off and relabled used tubes. Then there were companies that took receiving tubes-"pulls" or seconds-and relabled/reboxed them. Nothing is really new-China is just 50 years behind us!

At some flea markets and lower rent discount department stores they sell refurbished electronics. These are usually in a plain white box with a name brand stamped on it. The local Roses typically has some Emersons or Samsungs like this. Warning on the box that what's inside may differ from the display. Might not be so bad, might have really been fixed at their US facility where an expert tech fixed the bad solder joints. But who really knows? Thing is that the price is usually about in line with what Wal*Mart charges for a brand new one. It is hard to believe how cheaply they can produce things. A non-electronic example: a local company sells supplies to airlines, hotels, etc., including washcloths. These used to be made locally but are now imported from China. One enterprising fellow buys bundles of cloths from them and then goes around selling them to people for shop rags. I bought some from him and they serve the purpose just fine. I paid him $20 for a bundle of 2,000 all cotton terry cloth washcloths. Once you cut out all the middlemen, how much do you suppose the girl who sewed them got paid?

I know, Im just suprised they'd go through the trouble of making a disposable chassis modular.

The CRT failed and someone replaced it with one from an old monitor?

In fact, they're almost impossible to repair as they're fitted with weird Chinese custom made ICs and transistors you just cant get for love or money...

Turkish and Indian made sets are exactly the same kind of junk... or even worse

Few people want CRT based computer monitors anymore, and maybe someone had a warehouseful of VGA CRTs to unload. And some TV makers love to score a bargain...

I didn't realise it the other night but that modular chassis has Funai all over it. Worst shit I've ever seen.

Most of the cheap Chinese sets I've seen use a pretty standard selection of parts. Sometimes the ICs in the Chinese sets have nonstandard part numbers, but I've been able to find an equivalent by googling the unknown part number. Often I'll end up in the pages of some Chinese forum, but the part numbers are readable. Every Turkish Vestel set I've seen is full of Philips parts.

So far the only odd parts to completely stump me are the Russian ICs I found in a Teac set.

The most common faults in the ones I find are horizontal output transistors (which are easily subbed), bad capacitors, and power supply faults caused by power surges (usually takes out the rectifier/diodes, chopper transistor and some resistors).

Well... some exaples of sets i had to scrap due to unavailable components.

Turkish made Goodmans (Beko): the controller chip was made by Micronas and was absolutely unavailable as a spare part... landfill

Indian made Hortz: the switch mode power supply was based on a 5-pin power IC, absolutely unavailable... landfill

Chinese made United: same SMPSU story as above... landfill

You can't even get any kind of schematic or service literature for them... they're even nastier than plasma or LCD TVs...

On the other hand, the schematics for most European and Japanese sets are readily available.

The first Beko I've seen just came in the other day. I haven't looked at it yet and I already get the feeling it's scrap (no remote and no access to AV or menus via the front panel makes it unsaleable). I've yet to see an Indian made set, but for some reason I expect they're worse than the Chinese ones.

I suspect most of the cheap Chinese sets here come from the same factory regardless of what brand they have on them. Most of them have very similar chassis. Strangely, I did find the schematic for one set in it's box. I don't know if it was supposed to be in there, but it was. I've also found a couple of phonebook sized Chinese electronics magazines full of copied schematics. Maybe it's time to learn Chinese.

I have pretty much given up on the local parts suppliers for ICs. If they do have it they want way too much for it. I recently needed a convergence IC for a Philips rear projection TV. The local price was $71 each, but I could order it from the USA for $9.99. Others with better connections than I have order their parts directly from China.

I can almost guess which 5 pin SMPS IC you're referring to. That's one I have encountered and I couldn't get it either. The USA supplier I normally use listed it in their catalog, but it was backordered for a month and I couldn't wait that long for the rest of the order.

I salvage most of my parts where possible. Most of the sets I find wouldn't be worth fixing if I had to buy the parts. The sets that aren't worth fixing (bad crts, badly damaged cabinets, parts unavailable, etc) get scrapped and their chassis go into the pile to provide the parts for the ones that are worth fixing.

approx 12 years ago,i went to a sale at the sun tv warehouse building. i purchaseda daewoo 25 inch set in the box for 69.00. got it home and the crt was shorted. i took it back under warranty and the tech told me the tube was rca . it was shorted because it was a used tube in a new set. he said that many overseas manufacturers were recycling old tubes and thats why they had a high failure rate.they replaced it after 3 trys of making adjustments. very bad service-led to their demise. they installed a used tube also,but for 69.00? it is still around ,in my daughters home ,used by her kids.

Penn State University Salvage has multiple pallet loads of CRT monitors of all sizes every time that I go there. There are literally hundreds of them all stacked up every which-way and shrink-wrapped waiting to go to a wholesaler, then on to who-knows-where. (After reading this thread, I wonder if they are coming back across the pond to a WalMart near you?) These are not the 13" and 15" monitors from long ago. They look like they are all name brand large screen CRT monitors that are no more than a couple of years old. Sometimes there is not enough room indoors for the pallet-loads of them so they sit outdoors. There is a constant stream of monitors and pretty recent looking PCs that pass through that place. In my shop I still use a perfectly good 17" CRT monitor that I paid good money for at least five years ago. Heck, the old PC runs Windows 98, but it still gets me to Google and most importantly it gets me to AK whenever I ask it to.
