Samsung LN32C530 will not turn on. Standby light just blinks

[mmclende]

I recently got a Samsung LN32C530 from a friend because it did not turn on. When it is plugged in the standby light turns on, but when you hit the power button it just blinks 4 or 5 times and then turns off. The person who had it before me thought it was the capacitors so they replaced those and I thought it was the main board, but after replacing that the tv will still not turn on. I have attached pictures and would appreciate any help given.

The capacitors that were used as replacements appear to be general purpose, and are completely insufficient for the application they are used in.

Ok, what type of capacitors do I need?

Panasonic FC, FM and FR are commonly suggested around here and can be acquired from Digi-Key for about $10 total. The question is - did the person replace all caps correctly, so are the specifications (uF and voltage) correct? You cannot be certain...

No I can't say. I found the schematic for the board so I'll verify that the capacitors match that. Are those capacitors something that I can go to Radio Shack or somewhere to get or would I have to get them online?

That looks like where your friend got those from. Go to DigiKey if you need help post back here. Make sure about the size, diameter and height it looks pretty crowded on the board.

Looks like Digikey has a better supply of FM's. Get the uf and voltage along with sizes and you want radial type caps. Try this URL:

You should be able to get what you need. Get shipping by First Class Mail it will get there in 2-3 days

Ok sounds good. Thanks for all of your help

Re: Samsung LN32C530 will not turn on. Standby light just blinks

So I replaced the capacitors with capacitors that matched the specifications off the schematic for the board and i am still getting the same issue. Any other ideas on what could be wrong?

Thanks

What happen if you disconnect the cables to the Inverter board? By the way, does it make that Samsung start up tone?

Sorry for the late reply. If I disconnect the inverter board the screen turns on and the Samsung start up sound does not happen when I attempt to turn it on.

That usually indicates a problem with the main board but pictures are really not good enough for troubleshooting j- they should be a s clear as these

Are these pictures clear enough? I believe it is a problem with the Main Board also, but I can't narrow down the issue. I have already bought a new main board, but it is possible the new one has the same issue.

Any ideas on what I can diagnose further?

I have the exact same issue, with pretty much the same specs.

Any advice would be much appreciated.

I know there is a firmware update, but i can't apply it because i can't turn the TV on. I'm also not convinced it would do anything.

I'm curious if this was resolved. I have the same issue. Any feedback is appreciated...

I have researched this issue on the model extensively. The problem is almost always the Main PCB. So much so it is very difficult to find any supplier that has a new, refurbished, or even a used one.

Does anyone know of a shop that you can send these to for repair?
