Re: Samsung PN60F5350 - Power Supply Board?
I know it’s been a few months but I finally got around to ordering a replacement main board and swapped out the existing board. TV is as good as new now! $30 for the tv, $75 for the main board. Not bad for a 60 inch plasma!

Re: Samsung PN60F5350 - Power Supply Board?
Is it more economical to buy the eeprom for $20 (with shipping) or the whole board for $42 (also with shipping)?Leave a comment:

Re: Samsung PN60F5350 - Power Supply Board?
Which one is the eeprom?...Leave a comment:

Re: Samsung PN60F5350 - Power Supply Board?
I did some digging on google and found a few threads where the main board dies and shows these symptoms. Would the eprom be enough or are there other components to consider?Leave a comment:

Does it have to stay grounded or only grounded momentarily?Leave a comment:

Re: Samsung PN60F5350 - Power Supply Board?
There was no change in the pin 1 reading when the power button is pressed. Stayed at about 2.4v. I also did not get a reading from VS-TP (the post above the VS-ADJ).Leave a comment:

Re: Samsung PN60F5350 - Power Supply Board?
Forgive my ignorance but how do I probe the pin while the connector is attached to measure the change?Last edited by overdrive1012; 06-21-2018, 10:02 PM.Leave a comment:

Re: Samsung PN60F5350 - Power Supply Board?
I got 4.2V from the standby pins. The large caps each read 170V. Looking at the heat sink there is what looks like 3 MOSFETS that are surrounded in silicon. Is one of those the standby IC’s?Last edited by overdrive1012; 06-21-2018, 08:47 PM.Leave a comment:

Re: Samsung PN64D8000 - Power Supply Board Issue?
So, impatient as I am, I ended up picking up a TV on craigslist that had a broken panel for $30. Power supply was good so I just swapped it to this one and I'm back in business, but will eventually fix this one as a backup.Leave a comment:

Samsung PN60F5350 - Power Supply Board?
So I stumbled upon a TV on Facebook Classifieds for parts and picked up this TV for $30. The seller claims that the tech that came out to his house said it only needed a power supply board. Before I went and ordered one, I wanted to see whether it was truly the power supply board or something else, since there is not power and no indicator LED's.
The first thing I did was test continuity on the in-line fuse and it is still good. Without testing anything else yet I did a visual inspection and noted a few things that look like they could be causes.
The circuits marked... -

Re: Samsung PN64D8000 - Power Supply Board Issue?
This is the thermistor that blew. I'm going to pull the board and see if I can see any other damage.Leave a comment:

Samsung PN64D8000 - Power Supply Board Issue?
We were watching TV the other night when I heard a pop followed by the TV going out. No standby light, nothing.
Immediately, I opened the back and noticed that one of the fuses on the board (BN44-00447A) had blown. I thought I could replace the fuse and cross my fingers that nothing else was bad. I replaced the fuse and plugged in the TV, immediately the other one popped. I replaced that one and plugged back in and this time around I heard/saw a pop, which tripped the circuit breaker. This time around, a thermistor blew.
I'm thinking that before I replace that thermistor,... -
