Re: looking for diagram...please help..

Here's the schematic diagram:

thanks for the effort sir...

the power board image shows on you've givin to me was not the same here at mine..

sorry for the mistake sir..

its my fault..

here is the model again:

brand: acer
model: X193HQ A
version: X193HQ Ab

this model here does not have a builtin speaker..

sir if you have another schematic can you upload it here sir?

thanks again..

 

[mister_rf]

Can you take some picture of the power PCB and the IC802?
Maybe we can solve the problem without a dedicated schematic.

here is the picture...

good day to all

There are some circuit’s to fit that application.
e.g
TOP223/TOP224
By the way there’s a missing pin? :-D
See also:
TOP245/TOP246/TOP248/TOP249/TOP250
TNY280
In order to determine the correct replacement need to have a clear picture of the PCB solder area. (or you need to compare the diagram to the IC pinout examples I have posted).

 

[bonskie3k]

thank you very much again sir...

try to buy first if there is in market here that has the same number..

lcd monitors here at phillippines are hard to find one..

wish me luck..

 

[mister_rf]

Have you already decided about the circuit type used for that monitor?

Also need to check for :
VIPer12A, VIPer22A, TEA1521, TEA1533, FSD210, FSDM0365, FSQ0365, FSQ0265, DL0165R, FSDL0165RN, ICE2A0565, ICE2A0565/165/265/365/765I/765P2, ICE2B0565/165/265/365/765I/765P2...

here is the solder area bro...

this ic would bi fit and the only available here at my location bro..

TOP245

 

[mister_rf]

Maybe that’s not the TOP245 circuit…

One more question, the IC has in a total of 8 pins (including the one not connected)?

sorry bro upon reading again the circuit i found out the the right one for my power board was TNY280..

yes sir it has 8 pins including the 1 that was not connected

In order to find a suitable replacement and solve the problems, you need first to have a complete diagram. As long the green paint cover all the PCB area, it’s impossible to get a clear image, so try to lit PCB from below and take some photos of the circuit.

 

[bonskie3k]

i found the exact number of ic802..

TOP258PN

what would be the replacement for this part?

here in my location i can't find one of this..

 

[mister_rf]

Take some pictures as I have requested and provide a list with all available SMPS circuits in your area. (e.g. VIPer12A, VIPer22A, TEA1521, TEA1533, FSD210, FSDM0365, FSQ0365, FSQ0265, DL0165R,FSDL0165RN, ICE2A0565, ICE2A0565/165/265/365/765I/765P2,ICE2B0565/165/265/365/765I/765P2 / TOP223/TOP224/TOP245/TOP246/TOP248/TOP249/TOP250/TNY280). In my opinion that’s the quickest way to find some replacement.

Hi everyone!

I need a scheme for Acer LCD monitor, model V203H C. board: TU08q98 IC601

 

[Marko Zmej]

Hi

I see that no one responds.
I have a Acer LCD monitor, model V203H C, lightning struck and board TU08q98 exploded IC601 and q601 and can not see labels replacing them. So if anyone has such a scheme or board to read the label, I would be very grateful!

thanks

 

[Marko Zmej]

It the board where I can not see the numbers on IC601 and Q601
