DVD player ICs -- surprising values

I've been attempting to assign rough values to ICs found in consumer electronics.
To do this, I've been google searching the the IC part #'s and comparing prices on multiple parts supplier sites. Here's a recent curb find.

Pics from the disassembly of a Panosonic DVD Player.

Surprisingly, several ICs seem to have significant spare parts value.
I was very surprised, considering the sum of the ICs values seems to be far greater than the value of the DVD player. These ICs seem to be various types of microcontrollers. Perhaps they have broad spectrum applications or perhaps scarcity is responsible for the price.

Some examples:
1) Panosonic MN677511DE (price range ~$130)

Could you cut around the chip and send it attached to the board for the customer to detach themselves? If they are good enough to solder it they are good enough to unsolder it. They might prefer it that way so they know it's not heat damaged.

Just a thought.

Parts like http://www.flickr.com/photos/4886509...57629419048066 you will not get off a board without damaging it. No matter how careful you are, you will bend or break off pins.

We are a toss away society. How many people are ACTUALLY purchasing parts like that to repair items. I live in a community of 125,000 people. We have two repair shops that do board level repair, and mostly only on LCD.LED Tv's. Everyone else swaps out a board, or the consumer replaces a whole unit!

@ Thortek. I too am wondering what is the market for these ICs. I imagine there must be a market somewhere. I say that because I've been checking many different ICs from various low grade circuit boards derived from CRT TVs, CRT Monitors, DVD players, etc. I've found quite a range of prices for various chips -- ranging from $1.50/chip to $18/chip for the microcontrollers from an old CRT Monitor, to the $130/chip for the Panosonic DVD microcontroller listed above. Presumably, if there were no active market, prices would gradually drop until they equilibrated near scrap value. The range of prices suggests to me that there are either varying levels of demand or varying degrees of market supply cornering.

Here are some other examples mentioned in an earlier post from a CRT Monitor Breakdown....

The integrated circuit shown in this picture (see links below) is made by ST microelectronics and it sells for $18 from a spare parts supplier.

The chip is a deflection processor: http://www.datasheetdir.com/TDA9103+XUnsort

This other integrated circuit from the same low grade board (see link below) is made by National Semiconducter and it sells for $1.79 (+$22 for shipping) from a spare parts supplier:

The chip is a RGB (Red/Green/Blue) video amplifier -- further details: http://www.alldatasheet.com/datashee...C/LM1281N.html

@JPete,
Thank you for your input here. Those are really good points that you raised. I wondered about precisely that sort of thing. I wonder if these various IC parts suppliers (there seem to be quite a few all over the US, Inida, and China) are buying unused parts new and in bulk and then sitting on them for years. (I believe Mechanic688 had a friend who did that with CB radios).

I have seen a few parts suppliers mention that their non-socketed, punch-through chips have been pulled from boards and then stored in static free bags (see the item description in the ebay link below). Whether or not that's the norm seems unclear to me. Perhaps it varies from chip to chip depending upon the scarcity. But I guess if you were selling pulled chips, then you would need to establish a good rep for doing it properly (thermal profile, solder removal, etc) to soothe the understandable concerns of any buyer for used ICs.

This doesn't surprise me at all. I am a Lionel train guy, and I used to buy and sell on eBay.
There are postwar cars that you can't get 5 bucks for, BUT if you remove the trucks you can sell them for 10-12 bucks a pair, and
then you can get 5-10 bucks for the car body itself. Makes NO sense!

For $130 I would just send them the whole board.
