Answers :

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

Samsung PN50B450B1DXZA will not power up. When I try to power it on, it makes a clicking sound and then nothing for 10-15 seconds and another clicking sound. The Red LED on the front flashes when it clicks but nothing ever appears on the screen. I removed the back of the TV and inspected Capacitors but do not see any that look to be bulging. When I try to power it on with the back off, I see a green light quickly flash on a logic board just below the power supply board. Are these clues helpful

I have a samsung lcd tv model LNS-4095DX/XAA. I am getting snowy particles throughout the image. The picture looks great except for the pixel looking particles throughout the screen. I have already replaced the power supply due to some bad capacitors. It was alot worse before the new part. Do you think it is the T-Con or main board that needs replacing? I checked all the connections and tried different cables to see if it got better, it did not.

I think I shorted out the power supply board on my Onkyo HT-R667. I was replacing some the capacitors to repair a hdmi switching issue. I was testing the repair with the top cover off. While it was powered on I accidentally touched the metal top to the top of the power supply board CMKM-P3X. There was a spark and the unit turned off. It won't turn back on. No lights. Can it be fixed or can I purchase a replacement board if this is even the issue. Thanks

Vizio VP322. Replaced 3 bulging capacitors on power supply. TV worked great for about 2 days. Now it wont turn on. The Vizio is lit up orange on the bottom but thats it. If I unplug the wiring harness going to the input board the screen will light up black but goes back out as soon as plugged back in. If I unplug all but the AC power cord I get 5V off power supply on one and 200 on both VS and VA. I'm not detecting power at those when all harness are plugged back in.

Samsung PS-42Q96HD Hi My Samsung PS-42Q96HD went dead one day no pic and no sound- so I opened up the back and on the psu I replaced 2 bulging capacitors.

Any ideas would be greatly appreciated. Thanks in advance

My samsung 46 inch LCD also has the problem of no picture, but clear sound. I read all the posts about capacitor problems, and have gone so far as to take the back off and the power supply cover to look at the capacitors. But they all look flat...I don't see any of the bulging noted in other posts. When I first power up the TV, it looks like it is lighting up, but after maybe 1/2 second of buzzing, the dim light goes off completely. Looking at it from the back with the cover off, you can see the

As I switch on my TV LCD Samsung (model LE37A656A1FXXC), some vertical coloured lines (semi-transparent though) appears in the left-center of the screen. After more than 30 mins they disappear and they come back from time to time. Unfortunately my warranty has expired. Someone says it's a problem with the T-CON Board.
