My Samsung SP-R4232 has some type of power supply issue. I called a tech who came out and verified it. He thought it was the main power board, but wanted $400 to fix it when I found the part online for $75.00. Part replaced. Blue light surrounding power button went from only four sectors lighting up for about 10 seconds to all, but one sector lighting for about 10 seconds. Same intermittent clicking sound continues. Any ideas?

Plasma TV does not use inverter back light board, you may have power supply or x/y driving board problems.

My samsung plasma tv went out and it just makes a clicking noise and wont turn on i replaced the power board but it still does the same thing help anyone!
It was not your power board, Thought the same on several repairs.Found out it was the main board. The clicking was the tuner relay. I bet you own a SP-R4232. If so,The part you need is BN41-00574A. Also might be under BN94-00669A. Hard to find. Try Shop Jimmy/Or Encompass Parts. Not cheep tho. Hope this info helps.
Have a happy new year. Todd

SSP-R4232 Plasma TV, blue light on, but tv wont turn on.
At this point it appears that your main board is probably bad. You most likely have a 5 volt scource going to the main board but its not powering up the set. The main board is part number BN94-00796A.
You might want to have a technician look at the TV to verify this as the issue before purchasing it. Please take a few moments to rate my answer. Thank you.

SP-R4232 does not turn on, makes clicking noise
Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. Or, something simple like a blown fuse inside the TV. The most common board to go bad is the Backlight Inverter Board. It what supplies power to the screen. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:
1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.
3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.

I hope I shed some light on the subject for you.

Remove the power supply cable to Y Main board, check Vs on power supply board when you turn on tv.
1. If you have normal Vs, replace the Y Main board. If still not work, replace the Logic board.
2. If you don't have normal Vs when you try to turn on your tv, just replace the Power Supply board.

Audio but no video
If the screen is not illuminated this can be from the screen power supply, the main screen driver board, or the screen itself has failed. The service rep will change boards to service this, and adjust as necessary.

The set will require factory level service.

Electricity went out in town, tv won't turn back on.
On this type of problem, the first thing I check is the AC line fuse on the power supply. Follow the Ac plug wire to the power supply board and where it plugs in, you will find the fuse. If: Then: It checks bad. Replace it. It goes out again. Call a Servicer. It is good. Check for the five volts that goes to the Main PCB. No five volts, change the power suppy (SMPS) Five volts is there, more than likely the Main needs replaced and SMPS. For a Samsung Servicer in your area: 1-800-SAMSUNG
