Re: Ps-50p96fd
how long is a piece of string?need more info,what have you tested,what do you have to test with?looks like a plasma by the model code,i dont do plasmas,some on here do,put up a bit more information first.
fixed so far...376 lg lcd tv's,24 onn tv;s,24 panasonic lcd,16 jvc lcd,12 marshall jcm800 amps,refurb of various disco equipment lighting,old style disco decks ,and a flymo!

Re: Ps-50p96fd

It works normaly, then i wanted to TURN ON again and red power LED started to blinking every second and TV wouldn't turn on anymore.

Re: Ps-50p96fd
Ok pictures are quite good but are off-site I and some other members would prefer if you could upload them
Welcome to the forum-
We can help a lot more if you please post good clear pictures of the whole chassis, and then pictures of each board, front and back and close up of connectors, (max resolution 2000x2000 and 2MB) using the manage attachments button, which is found by clicking "go advanced" under quick reply.
Please do not post inline and offsite as they slow down the loading of pages.
It will be useful if you can say what the supposed fault was and a bit about yourself - skills tools etc. Do you have a multimeter and soldering equipment.
The two small caps at the bottom look bulged to me and one at the top looks odd but the flash has washed it out so cant tellAttached FilesPlease upload pictures using attachment function when ask for help on the repair

Re: Ps-50p96fd
The one at the top is OK, it's just bad angle and flash.
The 2 caps bellow are on IMG117.jpg and also looks bad to me. Uploaded 4 more pics of these caps. One is definitely leaking other one looks close to it.
I've got good soldering skills and i can borrow multimeter. How can I really find out if these caps are bad or OK?Attached FilesLast edited by sekino; 08-11-2012, 06:09 AM.Comment

Re: Ps-50p96fd
Those are definitely bad. They look like Samwha caps - a bad manufacturer, I've replaced too many of those. I think the count is 23 now over two LCDs and two plasmas (both LG or Samsung - the only companies that seem to use these crappy caps.)
You should replace them with caps such as Panasonic FC/FM/FR, Rubycon ZLJ/ZLH, Nichicon HD... do NOT use general purpose caps.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Ps-50p96fd
Ok Samwha caps are not very good - closely check others on the board we would normally recommend changing any of the same make and series.
How is it in Slovakia for getting replacements - general purpose caps are not really suitable for this application and you should try and get some with low esr (obviously same voltage and capacitance.) At a minimum get some with 105 degree temperature marking.Please upload pictures using attachment function when ask for help on the repair

Re: Ps-50p96fd
What parameters should be the new caps? Same 10V, 2200 uF, 105 C? what does it mean LOW ESR? can u put some google image of good caps?Comment

Re: Ps-50p96fd
Panasonic SERIES FR FM FC
Nichicon
Rubycon
Are all good makes if you go to Digikey.com you can get details.
You may not be able to get them in Slovakia or the price may be prohibitive.
If you have a local electronics shop you will have to ask if they have any
low esr caps. - There are many threads about it on this site use the search

Re: Ps-50p96fd
I've looked at DIGIKEY for capacitators I need, but they all are GENERAL PURPOSE, what purpose they should be?Comment

Re: Ps-50p96fd
Hi - yes its a bit confusing digikey only designate panasonic FC FM & FR
as general purpose but you can ignore that - threw me for a while - if you want to post the digikey part nos we can say if they are ok.Please upload pictures using attachment function when ask for help on the repair

Re: Ps-50p96fd
Don't use them, they are general purpose caps. You have already, but don't be surprised if you have to open the TV up in a year's time to replace them.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Ps-50p96fd
Hi guys
I seem to have the same problem with my Sammy.
Is this an easy fix?
Where is the best place to get the Caps I need in the UK please?
Should I change out any other Caps whilst i'm in there?
I know questions, questions, questions

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.
Assuming... -
I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time... -
Hi everyone,
I'm troubleshooting a power supply issue with a Sony SLV-E780 VCR. The device clicks repeatedly but doesn't power up completely. I've already replaced five capacitors, but the problem persists.
Here's a video link https://photos.app.goo.gl/3Xki6yvCLn67gLX78 showcasing the sound. Based on your experience, could this be due to a transformer, diode, or another component? Any guidance on what to test or replace next would be greatly appreciated.
Thanks in advance for your help! -
Hi all, I have a problem with the following TV: I'm sure the problem is with the power supply..... in fact I tried a power supply that they lent me bn44-00473b instead of the original one bn44-00473a and the TV works normally .. .
The defect found is that the LED emits 5 double flashes and does not turn on.... can you tell me which section to check or better, what tests to do? Thank you
