Samsung LN32A330J1DXZA will not power on. Problem occurred after moving TV from one house to another. Samsung Capacitor repair came out and pronounced it a dead main board and did not perform any capacitor nor power supply board change. Is the main board worth replacing? TV is 5 years old.

Hi,
You have to check and replace the electrolytic capacitor in the power supply board of you tv. some time bad electrolytic capacitors in the power supply can cause power on problems.

Hi,
Your TV have problem with the back light inverter board. This type of complaint can occur under two circumstances.
1.Faulty electrolytic capacitor in the power supply board
2. The back light inverter board.

If you have knowledge in electronics then check the power supply for any faulty or budged electrolytic capacitor. Have adde the picture of faulty electrolytic capacitor how it will look like. check the link. faulty capacitor .

If the are no such faulty electrolytic capacitor then you have to replace the back light inverter board. There is no repair possible with inverter board because its spares are rarely available.

You have didn't mention any model number of your TV. so its not possible to add the exact picture of the inverter board.

That set had a big problem with capacitors. If you are experienced with electronics, then change out the group of caps on the top of the power supply. They should be marked as 2200MF at 10V. If you can not do this I would take it to a authorized service provider. It is a cheap enough repair.

There are probably bulging caps in the power supply, youtube are getting better at showing how to repair tv's, you can look and search how to repair samsung tv, it will give you the best result possible if you are a DIY.

You likely have a power supply capacitor(s) that has gone bad. This is an easy fix, and I suggest you search youtube for "samsung capacitor" and you should get some good videos how to repair it if you can solder. If not, any friend who can solder can probably help you repair this with a couple dollars worth of parts form Radio Shack.

Check your : - Power cord ( the presence of power) - Fuse Replace them as necessary. If booth of above working well, you need to check power circuit in your TV ( This will required advance TV knowledge).

I had the same problem with my Samsung LN26A450 LCD TV. I found the following YouTube video http://www.youtube.com/watch?v=Mm51C_RDIZE titled "Samsung TV Repair - Part 1 of 2) (also watch Part 2 of 2) which shows how to easily fix the problem. The problem is bad capacitors on the power supply board. My TV had seven (7) bad capacitors - all 7 had dark stains on the ends from leaking electrolytic fluid and one (10V 2200MFD) was blown with bulging ends. I ordered 7 new high-temp (105 degrees C) aluminum radial capacitors from DigiKey.com matching the Temperature, Capacitances and Voltage Ratings for each damaged capacitor that I removed. I followed the instructions in the video except I used desoldering braid ($3.99 at RadioShack) to remove the solder attaching the bad capacitor leads to the power supply board. Once you wick up the old solder from all sides of each lead wire using the desoldering braid, the bad capacitors are easily removed. Total cost of repair including soldering equipment was less than $50. Thanks to “The Professor” for posting the video and saving me $400.

How to fix it.....
It totally worked for me....
