Hello everyone, I have an Emerson tv that recently got damaged due to a lightning strike. It has picture and sound but I heard a buzzing sound coming from the back. i opened up the tv and traced it to a blown capacitor. now I have no expeirience with electronics, but the field had always interested me. anyway I am trying to find a replacement capacitor but ant find the values on the capacitor itself, I dont think. I hope the picture helps. Thank you in advance for any help or information.

Re: Emerson LF320EM4 A after surge
The values will be on the other side. CARE when handling - set off and unplugged - even then you should test across the legs with a multimeter on volts DC 600.
It is probably 100uf 400volts
They are usually glued down?Please upload pictures using attachment function when ask for help on the repair

Re: Emerson LF320EM4 A after surge
A small amount of force prying on the non-lead end should free the cap from the glue. The only caution in that is to not damage the board with the tool used to pry it off.Comment

Re: Emerson LF320EM4 A after surge
Why do you think it's bad? Those rarely fail. If it's buzzing, the rectifier may have one side out Check the voltage.
Set meter for 600V, check across the two pins. Be careful NOT to touch any of the heat sinks as they will be hot and can give a nasty shock!!Last edited by truep; 08-03-2014, 09:05 AM.Comment

Re: Emerson LF320EM4 A after surge
damaging it - just snip the legs and it might twist off the glue.
As it has leaked you should clean the area up with Ipa
Also perhaps test the rectifier - in case it has been damaged.Last edited by selldoor; 08-03-2014, 09:36 AM.Please upload pictures using attachment function when ask for help on the repair

Re: Emerson LF320EM4 A after surge
That's a 330uF 200v general purpose cap, should be easy to find and inexpensive. I agree you should check the rectifier and also check that fuse, F602.Comment

Re: Emerson LF320EM4 A after surge
200v - must be just made for the US market.
Hmm there doesnt seem to be an actual rectifier on this board it is 4 diodes
Please can you post a good clear picture of the top and bottom of the board

so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...-

by LEECH666Good day ladies and gentleman!
I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.
This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).
I think the PSU buzzing comes from one of the coils near the bridge rectifier but... -
by proxneoDear reader
I am performing a repair on a Sony ICF-SW55, which includes recapping (some) of the SMD capacitors on the mainboard. I am looking for verification of their values. At the moment, I'm 95% sure I've got the right values, but it is hard to find some official, credible or multiple independant sources on this.
At the moment, I have selected replacements based on the following list of values:
3 x 470uF 10VDC
3 x 4.7uF 35VDC
4 x 47uF 50VDC
8 x 22uF 6.3 VDC
1 x 220uF 6.3VDC
5 x 100uF 6.3VDC
Which...-

Hello to the forum.
My name is Christos, I am new to the forum here and i am posting from Greece.
So i have this old German sound card from Marian, called Trace Alpha. To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.
To be more specific in the same exact pc with windows 7 (i even tried 32bit) the one works while the other doesn't.
So i tried asking for a schematic from the company and they would not give me one. Instead they...-
