TV Repair Questions? Ask a TV Technician
Hi,I will try to help you with this question.
Is the TV 'clicking" or indicates any kind of power-is the LED lighting?Are you able to perform some voltage checks?-or other kind of troubleshooting?
There is no power at all.
Checked the fuse at the power supply and it has continuity so i don;t think that is the problem.
The fact that the fuse is not blown,it does not mean that the power supply is working.
This is a switching mode power supply and many other things can go bad without to blow the fuse,that is in the primary of the power supply.
Are you able to check the STB 5V out coming from the power supply?
Is it there?
The 5v you mention is by the caps that are known to blow.
If you could tell me how. I could check it.
Also, I have no problem buying a new power supply. Found 1 for about 100 on parts supply web site. I just don't want to start changing parts and that not be the problem.
First you need to check the 5V stand by at the capacitor C114.
Do you have any 5V on C114?
You should have this voltage as soon the power supply is connected to AC line without any command from the main board.
don't see c114.
All capacitors are labeled CM8__.
It should be on the power supply,see below:
But do not worry ,just check the same STB 5V on the big connector going to the main board.
It should be labeled as STB5V or only 5V.
I'm still looking for it. I can't seem to find anything labeled as such.
I don't do this much.
The print screen you sent said if the red indicater light is on to check this 114.
the light is not on with power up.
Is it your opinion that the problem is the power supply board?
The manufacturers have sometimes weird way to check things.
I would check this 5V stand By first,without to look at the LED,because this voltage is the one that powers the LED,once the LED is lighting,then I would say the the 5V stand By is OK!(since the LED is ON).
Yes,since you do not have LED light at all,and nothing happens when the power button is pushed,no clicking or any other power indication-I would suspect the power board.
But to be sure we would have to check this 5V first.
let me know if you have it or not
Just post back to the same question like now,and I will be able to see it!
Did you get the chance to check the 5V stand by ?
I don't know how to check the 5v stand.
So I ordered a power supply.
I'll try that first and if I still cannot get the set to work I will get back with you and
maybe you can explain how to check the stand if I can find it.
The other thing is that I paid ALOT of money for this set $3,000.00 and have it
for only 1.5 years. Needless to saty I'm P.Oed about it.
Samsung should buck up and fix it for free.
No problem,just let me know,and I will gladly help you.
