Re: Lenovo ideapad 5 14alc05
Hi! This programmer should be compatible with your BIOS chip [U]but you also need the 1.8v adapter / converter[/U] or you risking damaging your chip!

According to service manual (link [URL="https://www.badcaps.net/forum/showthread.php?t=118879"]here[/URL]) the PL602 is on 0.75V ALWP rail and not on 1.8V rail, so your problem in not there...Re: Lenovo ideapad 5 14alc05

Re: Lenovo ideapad 5 14alc05
Your BIOS chip is probably 1.8v device.
Did you use an adaptor to read it?

Re: Lenovo ideapad 5 14alc05
Thanks.
Mine is 14ALC05 not 15ALC05. Same motherboard?
Also this file and all files on this thread are very different from my backup.
Are these files suitable for flashing directly to the chip by using external programmer or are only used for software flash?...Leave a comment:

Hi all,
Can someone help me fix my bios?
Not sure if the bios is the problem but is the easiest to check.
Symptom is black screen with backlight on

Re: LG 37LS5600 blows main fuse
Ok found it.
Both measure 200 one way, slowly rising to 1600 from the other way.Leave a comment:

Re: LG 37LS5600 blows main fuse
Can't find D201 and D202. Maybe you mean D501 and D502 near ic501?
If yes they are reading: D501 with positive lead to cathode nothing.
With negative lead to cathode: 478
D502 with positive lead to cathode nothing.
With negative lead to cathode: 479
There is also D503 near: with positive lead to cathode nothing
With negative lead to cathode 476Leave a comment:

Re: LG 37LS5600 blows main fuse
It's about 3,5MOhmLeave a comment:

Re: LG 37LS5600 blows main fuse
Ic501 is 3BR4765JZ. There is very low resistance between pins 3 and 8 (2.3Ohm). I believe it's ok as per datasheet and created by R510 and R511 resistors.
Of course don't know if the chip itself is ok or not...
Optocouplers also not shorted.Leave a comment:

Re: LG 37LS5600 blows main fuse
Are you sure? It's between live and neutral. 10 Ohm it's almost short circuit......Leave a comment:

Re: LG 37LS5600 blows main fuse
Checked. Its not shorted. Reading 1.2MOhm in circuit.Leave a comment:

Re: LG 37LS5600 blows main fuse
Q601 and most, if not all, transistors and diodes are checked and are not shorted. Not checked all resistors yet, its a little bit difficult to read the color code but I will do it.
I know about the trick with the lamp, maybe I will try to build it if I can find a incandescent lampLeave a comment:

LG 37LS5600 blows main fuse
Hi all,
Need some advice to troubleshoot this TV.
PSU blow the main fuse F100, 3.15A.
I replace the fuse with another 3A (but not ceramic) and blows it again [U]after few seconds[/U] when i plugged in to the wall, with nothing connected to PSU, just the power cord.
I checked with DMM for dead sorts but didn't found any.
Checked bridge rectifier and seems ok.
Also check main filter cap with transistor / cap / esr tester (the usual cheap transistor testers from ebay) and found ok.
PSU p/n is EAX64405901... -
