I had a similar problem where the TV would turn on then shutoff when bumped or over time. The clue was a "tick" sound when it shutoff. Unplugging and reconnecting the power cord go it going again for a few minutes anyway.

I took the unit apart and found the solder connection on the power supply unit was cracked where the main transformer attaches. The solder connection joins the PC board. I suspect the weight causes the joint to stress crack. This is easy to fix by removing the power supply and touching up the solder connections around the transformer. I'd check this first as it is very difficult to locate power supplies and other parts.

Tv lost picture yesterday. Tv will not turn on now


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

We had a power outage and since my tv does nothing, a tiny red light says standby but nothing changes.

Samsung plasma TV model #pn42b400p3dxza problem with no image. The TV has sound but no image. I've tried using other components on the TV like RCA jacks with a separate TV digital tuner. Thank you

Check whether Va & Vs voltage come to the display panel, from the main power supply regulator board. If not, the SMPS board [power supply regulator board] is faulty.

If the tv was made before December 2008, there is a capacitor settlement from a class action lawsuit by Samsung. Supposedly (at no charge) they will send a repairman to replace the capacitors.
