Hi I recently got some time to work on this TEAC DV-28E laptop optical drive. The drive reads CD's and DVD's fine but it doesn't get detected. Tested it on some laptops and on an DELL optiplex gx280. Already tried to reflow the chips, but that didn't work. Any ideas?

Perhaps a silly question, but why was this video card getting re-balled in the first place? If it's because of artifacts , forget it - despite running hot, these old GPU won't run hot enough to crack the solder on the BGA package over time. And the GPU chip itself uses die bonding wires rather than …

What temperature did you set to remove gpu? The pcb is looking burned a bit 😀 Re flowed it many times using 360 C. To remove, i also used 360 C and 100 C from the bottom. As much as I like repairing stuff id look for another riva128, they start at $10, exact same Asus is $40-50 Buying a new card …

It would be better to take measurement without the cpu in the socket, there are some weird readings in your post, source of high side mosfets is connected to drain of low side mosfets and you say they have 2.4 and 4 ohms. also source of low side mosfets is connected to the ground and you say it has …

So it's getting the enable signal but there's no cpu vcore. Are you using the right cpu for this board? some of these boards don't work with willamette P4, only Northwood and Prescott. the next step is to check the mosfets, you need to measure the resistance between the gate leg of each mosfet to …

The resistance on standby 3.3v is pretty good. about the cpu is not getting warm, have you measured the 2 the inductors near the cpu socket to verify that you are missing vcore? if you are getting under 1 volt on those inductors, it could be the vrm pwm ic is not getting the enable signal or …

680μF 10v will most likely work just fine. What does the power good from the PS do? Power good signal, when mobo is on is 3.7v. If i jump start the psu without any load, it shows 5v. I will replace those caps and let you guys know if it did anything. Under the Intel logo is where the chip usually …
