I have a Polaroid FLM 373B that powers on but has a buzzing/clicking sound. I am able to access the menu but can not get any channels since it says " no signal". I replaced one bulged cap that was under the heat sink on the power board(the other caps look ok) but it did not change the problem. Anyone run across the same symptoms or have any ideas? Thanks

Re: Polaroid FLM 373B problems
You need to check your voltages on the power supply and see if they are correct. Pictures are very small to view.
Some good photo's of the power supply showing the pinout and voltage labels would be useful.Last edited by dick_barton; 10-04-2016, 10:58 AM.Willing to help but I'm no expert.Comment

Hello friends, I just received this equipment, it has a strange hum on the board. The computer works fine, outputs an image and starts Windows. But the problem is when charging the battery, a constant loop to charge. In short, it never charges the battery. When the charger is connected, the stability of the CPU is stressed and it seems that the coils make that electrical sound louder. This board is modern and I don't have a schematic. I have checked with a microscope and the pcb is completely new. Has anyone had this happen to them before? defect in driver ic?...

Hello,
on this laptop hp g72 b52sf i have screen problems as you can see with the photo joined in attachments.
the used graphic card is "intel hd graphics" and the id of the integrated screen is : "monitor/SEC3354".

Recently I discovered my SSD died (OCZ/Toshiba 240 GB). It was in a USB enclosure, attached to the Linksys WRT-AC1200 router. Since then I removed the USB enclosure and attached it to my Win7 PC (AMD 8150 CPU, 970 chipset, 64 GB RAM). I also gathered one or two other USB enclosures to figure out what is going on.
(I suspect that I lost quite a few MP3 and FLAC files I recently ripped from my audio CDs, I think I lost very little un-replaceable stuff.)
I think it is IMPOSSIBLE for Win7 to have any problems with a USB enclosure as long as Win7 knows how to speak to the... -
The PSU works, but shortly after powering on (either in the G5, or by shorting the power-on pin to ground) it begins buzzing loudly. It also makes the LED lights connected to the same circuit flicker. It's definitely a buzzing, not a high pitched whine.
The buzzing seems to come from the high voltage side of the board, perhaps from the white relay. Could the relay be bad, or could the 5V supply be bad enough that it's unable to keep the relay on? Any pointers to help isolate the issue? Thanks!

Need help to solve some problems with this laptop.
After working in bed with it one night and heating up too much (probably the cause of this problems) the sata HDD OS windows froze
After restart the original Sata HDD was not recognized anymore (but works fine in other laptops or PCs)
Tried connecting other good Sata 2.5 HDDs but not one is working in this laptop anymore (not the original nor others)
Before this had happened I observed some other problems:
When I tried replacing original mecanical HDD with a SSD HDD could not get them...
