Samsung plasma tv does not power on consistantly

My tv for the most part will not power on the first time. It may the second time but sometimes it takes numberous attempts to get it to power on. I changed the power supply board and it did not correct the issue.

I doubt that moisture damaged the SMPS bd.
There are many circuit boards in your set and it will take a trained samsung tech to find the problem.

SOURCE: Which Replacement Power Board for LNT4665F Samsung LCD TV?

Howdy,
It would be a lot cheaper if you just replace the two caps that have gone bad. Just get a cheap solder pencil from the store and about an inch of solder and you are in business.
The Power Supply Board is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thaks for using FIXYA, BIG IRISH.

You can't see if a cap is good or bad jus looking at them they have to be measured>They loose their capacitance because they dry overtime.
I do sugest that you replace you power supply module or replace all caps.Possibily you may have a broken line in the PCB

I have a 50 inch samsung plasma. It is getting lines all the way across the screen. I'm up to 47 lines is there anything I can do to fix it?


Several things can cause problem with plasma TV's. You may be getting electrical noise from an appliance or lighting such as halogen or florescent, dimmers, bad electrical connections and outlets. Also, bad cables can cause problems too; have you tried switching those out? Appliances like vacuums, fans, regrigerators, anything with a motor can cause lines and noise on TV's. Have you tried connecting the TV to a noise suppressing, surge protection power strip? Do the lines come and go, or are they consistently in the same place all of the time? When did you buy the TV and is it still under warranty or an extended warranty? Do you have problems with any other TV's in the house? Look at each of these solutions, try them one by one to narrow down the potential source of the problem. If you've tried everything I've mentioned, it may be a bad TV. It does happen, but not often. And as a former Samsung dealer/installer, I know Samsung products have really good track record. In fact, every TV and smart phone phone in my home is Samsung. Hope this helps.

Samsung plasma 50in PS50B550 clicking noise


The clicking could be a loose connecction of the power plug or frrom the main power unit of your TV. Remove your plug and see the ends for burn outs, if so clean and use a different outlet. If not open the set after disconnection and check your main power supply unit for loose connection particularily in the surge protector, the main capacitor, the main drive, diodes or connectors. Wait to hear the sound and use a long insulated rod as a probe to confirm the origin of the sound. Solder or replace the damaged item. Hope this helps . Good day

Samsung 50'' Plasma TV won't turn on anymore


If your tv is within the one year warranty period then call 1-800-Samsung for warranty repair. Look at your tv purchase receipt for the Purchase Date. You have one year from the date of purchase to get warranty repair.

It related with Power Board(50%) or Y-Main(50%).
But, if you use the power bar with surge protacton, need to check
the power bar's lamp when the TV is turning on & off.
