Asif2011 & NotSure;.....

I've spent about 30-45 mins searching the web for that IC including datasheetcatalog.com....NO LUCK...
There are a ton of websites that claim to have the datasheet for that IC , however when you get there , it can't be found OR it's for a different IC...

Good Luck with this one.... Sly

This link goes to an ""akira tv 21WHS/3B SERVICE MANUAL"" which is NOT in the original posters post...
http://www.scribd.com/...n-Chassis-Uoctda9381

AND the correct IC IS in it !!!!
EXCELLENT work jts , I NEVER would have found that...
I have NO idea HOW you did that , but that's AMAZING !!!!

As for;...
http://www.datasheetarchive.com/TDA9361-datasheet.html
The top line shows a TDA9361 , but you scroll down a bit & you get 2 downloads for a TDA9361 which actually turn out to be TDA935X/6X/8X instead....
That is for a TDA935X/6X/8X & is NOT the same IC as the one above this link...
(I found this data in 5 sec since I have this website bookmarked.)

So you have one positive & one negative which makes this neutral.... Wink

STILL GOOD job tho.....

Have a GREAT day & weekend....

Akira was 2nd on Google's list. They also list some others that use same IC.

What datasheet actually reads is: TDA935X/6X/8X PS/N2 series. Which I intrepret as the "X" can be replaced by any number. Both PS/NS series are covered.
That Datasheet is good for the following TDA's (page 4):
(TDA) 9350 9351 9352 9353 9360 9361 9362 9363 9364 9365 9366 9367 9380 9381 9382 9383 9384 9385 9386 9387 9388

When I Googled for the IC yesterday (TDA9381) , I got a ton (~48,400) listings , all of which I looked at said they have the datasheet , but instead are websites that want to sell you the IC , have links to other websites that also do not have the datasheet , have the wrong info etc....

I DID go to that website !!!
When I saw 9361 on the top line , & proceeded to the download & saw TDA935X/6X/8x on the opening page , who in their right mind would have proceeded to open that up & gone to page 4 but jts1957 !!!
Those wrong numbers to me were like red flags...
Who'd have thunk that that IC would have at least 21 different numbers but the same configuration ????

scribd came up , but since I'm on sloooow dialup , scribd takes a loooong time to load..
I gave up waiting because I thought "Who names their chassis after an IC ???"""
Another listing screwup , I thought....

Why build a different TV chassis for bottom & top of line sets? Just use the one chassis for both with more or less parts as required.

I guess that because that set is made in China , they want to keep it CHEAP , so they use only one chassis & keep it cheaper by naming it after the micro...Wunnerful.... Unsure

Not a sign of genius...
RCA did a similar thing with some of their chassis , (CTC169 comes to mind) but , they did NOT name them after parts inside...
Like "Flyback xxxx"...

When you are online , are you using IE , Firefox , Opera or ????

Right now I've only set up the speeddial buttons, one-button logins, etc. with Firefox. I'm pretty sure I'll go back to Opera once I start setting its speedials, etc..
On Firefox, when I try to edit a previously posted post it gives me all that html gibberish (example: <img src="http://smileys.on-my-web.com/repository/Respect/respect-055.gif" border="0" /> <br> <br>). I can restore then add to a short post easy enough, but I don't experience that problem at all when I'm on Opera.
IE is only used as a last resort. Rick also loaded Chrome, but I haven't ridden on it yet. Wink

I really don't expect a thank you, I do this for the fun of it, to kill time, show off, etc.

I had Firefox quite awhile ago & had glitches with it , so at the time I went back to IE-6...(Oh yeah , that long ago..)
Now with a newer computer & OS , it's time for me to give Firefox another whirl...THANKS for the info...

I do this for the satisfaction that I know I've helped someone fix their TV or helped them in one way or another...
I , as you , do not expect a "Thank you" , but it is nice to see one every once & awhile....

Dear Ron,
the problem is that i have bought this IC and now i am failed to place it in TV bcz there are other version of this IC that differs in code typed after N2. This IC is very costly and now i have to use it to get rid of this loss. U got my point Ron?
take care and Have a goood day

What was the complete number of the ORIGINAL IC?
I am assuming the REPLACEMENT IC is TDA9381psn23i0478.

What is the IC being used in? (Brand & Model number)

You know , had you given us that & OTHER info SOONER , we most likely would have given you different advice...
You did NOT say what info you wanted on that IC OR what it was FOR , just asked for help about the IC...
Had you told us "WHY" you needed the info , we'd have gone in a different direction...
We would NOT have wasted time & gray matter tracking down pinout info etc....
The IC is pricey because 1)..It is a microprocessor ...2)..It is made in China (I know that sounds odd , but..>>)..3)..Because it's ONLY used in a few CHINESE sets , they have you by the short hairs...
When we see that type of question , we think you are asking for a pinout on the IC for troubleshooting purposes...
U got my point , sir ???

My new questions are;=>....
Are you a TV tech ???
WHY did you buy the IC ???
Did you INSTALL it in the set YET ????
WHAT is/was the problem with the TV that made you buy the IC ???
Is the code info on the "original" IC different than the code on the one you bought ???..
I'm guessing it IS , but I want a definitive answer...

For better help , please answer ALL my & jts1957's questions....THANKS... Sly

Sly

.....

jts1957;...
As you UNDOUBTABLY know...
The numbers after N2 are the programming code...
This is a microprocessor IC...
Each model that uses this IC has a different code referring to features etc it is programmed to do....
Remember the older "TMP" ICs ???
Same deal...

Dear ron I am sorry that you are misled and i got your point. I answer your all ques.I am son of TV technician and Have degree of MSC telecom. MY father doesnt know the english language there fore he is not known to technical language of latest Digital CRT TV and not know the computer knowledge. I know english and some knowledge of technical lang of general digital electronics . My father have been repairing the TV since 18 years. He knows very well the old TVs but now in case of revolution of digital tech, programming lang creates problems. As my father is technician and seller of TV parts so that he buy the IC (TDA9381psn33I0478) for a LG TV, in which IC(tda9381psn23I0861) is used. But when he place this bought IC(TDA9381psn33I0478) in LG TV then problem was not solved. after placing the same original IC(tda9381psn23I0861) then TV did function well. Then he checked the difference b/w these both ICS and find the difference in code now those ICs(TDA9381psn33I0478) are not bieng sold and not we can use it in any TV. again I am sorry to u. I was considered that you will solve my problem by giving you early information. now U r cleared Ron and 1957? and this time i am known to that this code difference is due to programming difference. thanx 1957.
Thanx a lot
