Re: HP W2408 - no live, no reaction
Yes - it's audio amplifier. I remove chip - and when power is ON screen is RED GREEEN BLUE . Over and over again. No reaction to plug VGA cable or other. So i think MB is dead. I think about T-CON, but when it shows the colors rgb think it is OK?
I would buy a universal MB (google: V59) and connect. New MB costs ~40$ - it's too much. I do not know pinout's from MB and inverter.
Maybe someone knows? The supply voltage of the inverter, which is pwr_on to start PSU?

Re: HP W2408 - no live, no reaction
Ok i know it's TDA 8496L. Can I unsolder chip and turn on screen witout TDA? Why chip expolde? Ehh...

On the main board damaged the chip. Unfortunately, I do not know markings chip
I do not know why it happened. short-circuit was not .
if anyone knows indication of this chip ? I read only TD ( A ) ....

Re: HP W2408 - no live, no reaction
Now I know how to upload pictures
It does not look good Exactly, scheme is not available anywhere.
As I wrote in the next week, I check these elements and write.Leave a comment:

Re: HP W2408 - no live, no reaction
Thank you for your answer!
I've seen these places. What could be the reason?
I would like to fix PSU. Next week I peak up transistor, diode bridge and
I'll check. What else should I check? Whether the cause could be the capacitor next - its capacity has decreased and sailed a higher current?
Once I heard about this case, but I do not know if it's true.Leave a comment:

HP W2408 - no live, no reaction
Hi everyone, at the beginning I apologize for my language - I'm Polish.
I got the monitor from a friend. When using the monitor went blank. No LED blink, no reaction. He carried to the site, and he heard only "PSU is broken".
Technician tried to fix something - I see flux.
I not picked up the elements (i don't have now solder - was in the house)
I opened the monitor and took pictures. I measured transistors. For me - 3 have shorts. (Red on the foto have shorts between all three pins). Green don't have shorts.
Diode bridge is short (+ and -). I think,...Last edited by bartex; 03-21-2016, 12:49 PM. -
