I took IC602 out, but I still can't see the number.Attached Files -

You may have to buy a replacement kit (both boards for 70$) at SJ, look what that IC is, then sell the kit.Comment

I have found an IC that may be can replaced this.
Thank you for your suggestion but this behavior is as same as cheating. I myself have been working so hard for the happiness and well-being of all mankind.
Sorry I can't do that.Attached FilesLast edited by capwizard; 01-09-2019, 06:33 PM.Comment

Re: Sanyo FW50D36F no STB voltage.....needs the IC602 part no:
I have found an IC that may be can replaced this. It is a current mode PWM IC of which was designed for 3.3v STB.
In theory, if I put a 18650 3.7v battery. tv will work.
But problem is customer needs to charge battery from time to time.Last edited by capwizard; 01-09-2019, 06:32 PM.Comment

Strange phenomenon....after I took out 8 pin IC. tv has no 3.3v STB voltage. But tv still consumes current 0.051A .Attached FilesLast edited by capwizard; 01-09-2019, 06:44 PM.Comment

Have you tried cleaning the ic with alcohol to see if there is a partial number?Comment

Re: Sanyo FW50D36F no STB voltage.....needs the IC602 part no:
I see the picture of ic601 and it does look like most of the top of the ic is there, It looks like there is still some of the coating they use on the ic covering any number.
Sometimes if you look at it at a different angle you can see the number or whats left of it.
Also what is Q601, that might help in identifying the icComment

It might be a FA5640N, Page 36 has the schematic and it does look close.Last edited by R_J; 01-10-2019, 11:32 AM.Comment

Today I am the happiest man in the world.
I'm blessed and I thank God for every day for everything that happens for me.
I grabbed a LG plasma tv jurk board next to me. Pic1
took out the part. it is a PWM ic for 180v converter....replaced with ic601.
and I pray for the Gods....yes tv works.
Ps. The circuits are for both 13v and 3.3v STB.Attached FilesLast edited by capwizard; 01-10-2019, 12:52 PM.Comment

Is'nt that ic601? So what number was on the ic you used as a replacement? looks like it could be a NCP1200Last edited by R_J; 01-10-2019, 12:28 PM.Comment

Re: Sanyo FW50D36F no STB voltage.....needs the IC602 part no:
sorry. my bad. It's ic601
you are a genius. Yes I replace with 200D6 = NCP1200D60R2G.
TV has been working for an hour.
So the principle of pwm IC is probably similar.Attached FilesComment

Hi There!
I'm trying to help my friend who owns a restaurant be just bought.
He has a very long LED strip running along all the walls and columns. The strip is attached facing down 2in above the floor, using a wall panel that ends in a metal rail that finishes the panel underneath
It's stuck using, I guess, the 2 sided tape that comes with the strip
The issue is that like 1/2 of the full length, including 1/2 one wall, another entire wall, and one column, flickers after 4 or 5 minutes ON. Particularly it flashes staying OFF most of the time and flashing ON for 1 tenth... -
So My iPad was not charging and booting up . i went to a local technician and he checked with thermal and this Part marked in 1st Photo is Short.
So then i went on to boardview and downloaded the schematics and identified this part in 2nd Photo. Now i am confused what exactly is the part called ? where should i get this from ?
i contacted my technician and he sent me his BoardVIew screenshot in 3rd Photo. In his Boardview the part is called X2826.... Something
SO My main concern is what part should i order what should i search the name for ?
on Ipad... -
In the Panasonic service manuals, both in the board schematics and in the part listing, the part numbers that are given are Panasonic part numbers instead of the actual part numbers.
This is especially annoying for small SMD components like diodes and transistors when you only have 1-3 digits printed on the component body.
For an example, look at the attached PDF.
Do you have a way to cross reference the Panasonic part number with the actual part number?
Thanks....07-03-2023, 08:16 PM -
Hello guys. I'm a complete noob in electronics. I'd like to repair my child Lunii's (a "story box"), basically an audio player that allows the childs to choose between several options the places, characters, objects of the story, and then play a story according to the choice of the child. There is a screen that display the selected option before each choice. The Lunii fell and the screen is now broken.
I'd like to repair it (probably just have to change the part, because the lunii still works perfectly fine) but I can't manage to identify the part/order it online. Do you have any...02-17-2025, 01:16 AM -
Hi i have a smd part with probably mark "QO 11" or "Q0(zero) 11" on it, and its package is SOT89, i doubt its KTB1260 PNP transistor, but in measuring with diode mode of multimeter it shows number 1.4 between emitter and collector pins and its not open circuit, and .59 from collector to base and .8 from emitter to base , and these numbers doesn't match a pnp transistor, i couldn't find any part number and datasheet for it, does anybody have information for that part number?
I've attached pics of this part
Thanks...
