This Samsung LN52A750 had a heat shield over the PSU. Should I put it back on or not?

Re: Replace PSU Heat Shield or Not?
It's not a heat shield, it is an EMI shield. It's not critical and it may run cooler without it, but it will not be FCC compliant any more. I doubt it matters to you.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Replace PSU Heat Shield or Not?
It's not really if it matters to me. It's if it matters to whoever buys the tv. I'm selling it to a close friend of mine and I'd prefer that it doesn't hassle him.Comment

Re: Replace PSU Heat Shield or Not?
It may matter if your friend or any of his neighbors use medium wave or shortwave radio receivers. The shield will reduce the emission of signals that may cause harmful interference to these receivers. This would include receivers for the AM broadcast band, shortwave broadcast bands, amateur/ham radio bands, and citizens band.Comment

This shield probably just added a few dBs attenuation and got them into the OK band.Last edited by tom66; 04-04-2014, 07:27 AM.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Mounting and Handling Guidelines for TO220 TO220F TO247 Cases / Packages
The TO220, TO220F and TO247 are the popular packages for power devices because of their versatility and ability to dissipate moderate amounts of heat. This application note describes the basic guidelines for handling power MOSFETs in TO220, TO220 and TO247 packages shown in Figure 1. Please note that only mechanical and soldering guidelines are covered here. Additional precautions are required for isolating high voltage rated devices to meet safety regulations.

by acedogblastThis is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
by jordanaudio1Trying to learn electronics repair as a hobby. I have no formal training in electronics, circuits, etc. Everything I know, which isn't much, has been learned from watching youtube videos, reading books, forums, etc. This means, sometimes I have a hard time understanding and interpreting what's important when I look at datasheets, and such.
My brother has a TV that I'm working on now. He said he was watching it, he heard a loud pop and it went off. I used my DMM to check the fuse, it was blown. From watching lots of hours of electronics repairs on youtube, I figured that was just a...07-07-2025, 07:38 PM -
by harpdetecting heat with IR LED receiver
I have some dark IR led, and want to know if it is be situable to detect pure heat (not visable glow ir radiation) in well lighted desk?
So, if I put hand over it in near distance like few centimeters, that detect rising heat, not covering it from light.
Something like termal camera, but in one spot, any simple circuit?... -
by ludovikHello everyone,
i was reballing the power manger of a moto g84, after applying heat i tried to power on and it wouldn’t.
i injected 1.5v to some capacitor that seem in short because both side beep if tested.
when i inject i feel the cpu burning;
since the cpu is exactly on the other side of the board, is that possible that the heat from the reballing damaged the cpu? do you know where i can find schematics or what can i do?
i know this is not enough to explain the situation so if you need any other info ask me please!
Thank you very much in advance11-08-2024, 02:13 PM - Loading...
