    lp156whb-tla1 Burned U21

    I have this LCD panel with U21 burned at Tcon.

    I can't seem to find what it is to look for a replacement.
    Can someone help me identify it?

          Thanks! I'll try to find a replacement and check if I can find EDID dump too.

              It could be close to a M24C16-WMB6TG in a UFDFPN8(MLP8) package. I also see similar ic's marked 464F 8420

                      Need help to replace burned resistor in 350w atx psu
                      by mikey5791
                      Hi to all forum members,

                      Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
                      The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.

                      Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
                      Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor...

                      Magnum IA.100 Amplifier Switches on, No Output, Possible Input Side fault?
                      by flibidy
                      I have here a Magnum IA.100 which belongs to my parents.



                      The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.


                      Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.


                      What Ive done........

                      Where to find a very small fpc connector 0.3mm between 2 pins ?
                      by corrize
                      Hello, I search this connector (oxydated).
                      It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
                      I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
                      I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?

                      Do you know how to find this connector please ? What is the exact name for find it ?

                      This Dell computer is a pain in the a** because of it only has one memory slot this computer only had 4 megabytes of memory and slower than shit I found a 8 megabyte memory module and it is better but still slow as shit the maximum is 32 megabytes of RAM but I was not able to find one I found some that are 16 megabytes but they are 1600/128000 type and I am not sure if this computer will work with this type of memory or not

                      Dose anyone knows where I can find a 32 megabytes memory module for this computer because the battery still works fairly well still I would like to use it on my...
