CD Players/Drives are disposable. It will cost you much if you want to repair it (labor & parts).

It is more practical to buy a new one. Now a days, it is more cheap.

thanks for your responce. but i think you have thought that it is a computer cd rom but it is not. it is seperate ,it has no need of computer. it is idivisually plays cds.

I never found or hear about this problem. i think maybe it's a kind of updating firmware. everyboard should be have a firmware. maybe u can try look at ur cd player manufacturer website for asking ur problem.

the player is of not perticular manufacturer . it comes on many companys names of the same basis of function. i have just got some information about it. i heard that it is like ic writting like computers bios writting. can i know the instument name so that i write any kind of data on 15 pin of ic . thanks!

mangesh, if you live in India...the cd-player is available for as low as INR 2500...my advice...go for that...no local technician will be able to repair it by reprogramming the IC...

buddy...he doesn't say his cd rom is not reading the CDs...he says that the front contol-panel comprising of buttons is not working fine....get it??

When i bought a new player i have got this board. After some time this board get damaged and thats why i have to buy a new one . So I bought a new one which was cheaper than the orignal one. The problem is this board is not working with the front panel of the player. So i want to programme rom ic so that i can make use of front panel. If you know the producer how to programme the rom ic so that i can use front panel. Please tell in detail. I aslo want to know which ic programmer is best for ic writting . In Ic prog i have not seen the ic no 27c020 . I aslo want to know which hardware is the best as i have seen many hardware in the market.

maybe (as you did not give more info, neither on nerd-out forum hehe), this if for you h**p://[Only registered and activated users can see links]
Goodluck in youR trouble, if i may say so (i say it, so i may) :lol:

mangesh...dude...i merged both of your threads....perhaps you forgot that you have already created one thread asking same question... :)

man in my place cd roms are only 2,6 usd something, dvd 2nhand are arround 10,5 usd, why bother headache repairng that??

may be its short circuit problem. if you have a electrical tester you can actually find out if the electricity going to the front panel is good or is having a problem

thanks for your reply Kirketchel, but this discussion was over long back :)

closing the thread now.
Thanks to all for their suggestions.
