Hello. I found out a Sil9187 shorted on a philips chassis. Is it possible to replace it with Sil9287( have it on hand) or should i order the exact chip?

Re: Sil9187 Replacement
The following multiplexers can be used:
• Sil9187A (does not support “Instaport” technology for fast
switching between input signals)
• Sil9287B (supports “Instaport” technology for fast
switching between input signals).
The hardware default I2C addresses are:
• Sil9187A: 0xB0/0xB2 (random: software workaround)
• Sil9287B: 0xB2 (fixed) -

Replaced with Sil9287B. Working great. Thanks a lot for the quick response!Comment

Hello, this is my first post on this forum, and my first attempted to repair a TV.
My Philips 58PUS7805/12 stopped working recently. It is not that old, about 5 years. We were on a trip for a few days and when we came back, it had stopped working out of a blue (Perhaps our house was hit by a lightning strike? Don't know.)
Read from a guide that I should test if the screen shows picture with one of the T-Con cables disconnected. Did that, it showed perfect picture (first on left, later on right side).
Read also that we should test what happens if we... -
Hello everyone!
This is my first post, but not my first attempt to repair a TV.
So a few days ago I got this Philips TV (TPM4.1E LA), which produced weird symptoms.
There were no 12 and 24V, which was caused by a shorted schottky. I replaced that, the voltages are alright everywhere, but it still refused to turn on or even produce a standby light.
Thats when I removed the cover lid from the U4201, turns out that it badly burnt through, thanks to that replaced diode. It's an MTK MT8222TMMU, and I already found a replacement for it. However in the service... -
Hello guys,
I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.
I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow... -
Hello,
Not sure if this is the correct section, but I have a PS4 controller that I am trying to fix. It developed stick drift on the left stick and the usual simpler methods did not fix the problem.
So I went on eBay and ordered some replacement potentiometers. https://www.ebay.co.uk/itm/174967976757 is where I got them from.
I took the green potentiometers off the replacement sticks and soldered them onto the PCB. Assembled the controller and ran some tests. The drifting was somewhat fixed (not fully in center, but way better than before). However,... -
i have a 2020 macbook pro 13" A2251 with 820-09149 logic board so i found an issue with chip labeled U6903 according to schem. boardview using flexBV software, so i removed it from the board and the issue im having is that the chip says "07A08FI ELC180" on top of it but when searching for a replacement chip, i can find tons of identical looking chips that also have "ELC180" printed on them but the first set of digits is never the same so im trying to find out if i need this exact chip with these same numbers as mine and if not which ones are compatible as a replacement?...
