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) -
Re: Sil9187 Replacement
Replaced with Sil9287B. Working great. Thanks a lot for the quick response!Comment

hello everyone,
I don't normally do tv repairs but this is a case with my personal TV which got fried together with many other electronics in my house after a thunderstorm.
The TV is a Philips 65PUS8518/12 which had no power. I measured and concluded that the main board was probably fried through ethernet or hdmi. I found a board with same number 715GD328-M0F-B00-005Y (I had G) but from a 55PUS8518. The TV starts but the image is doubled, distorted. I need to set the panel code which is 016 according to the sticker on the back but I can not seem to do it.

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... -
Philips 8200 series 65PUS8204/12 stuck at Philips Logo, it does not reboot it just stays on the logo.
It does power up when pressing the power button.
I already try the power button while plugin the plug with no result.
Also put the latest firmware autorun-TPM191E_R.001.004.100.000.upg on a MBR/FAT32 USB stick at USB port2 with no result either.
Could this be an PSU or eMMC issue ? -
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...
