Question about Samsung Televison & Video

1 Answer

I have a samsung PN43E450A1FXZA Plasma tv. I have no standby light, no power on. I do not have PS-ON voltage or VS voltage on board. Any idea which component on the power board may possibly be bad?

I have checked the PSU board and have 5.3 stby volts, the 15 volts. I do not have VS voltage on power board test spot. I do have VA and VSC voltage as well as SVT_XOUT. I do not have any voltage on any pin on plug CN1201 on main logic board going to the on/off button as well as the standby light on front.

There is an internal fuse or capacitor that needs to be replaced. You can try calling Samsung directly for assistance and see it is covered under warranty.

Samsung Plasma TV has standby power but no video


Make sure your video and sound cable is working (rca, hdmi cable etc) and your source component like dvd player or settop box is working. If cable is plug into a socket AV 3 or HDMI 3 for e. g. make sure the tv is source or input is selected the same like AV 3 etc.

It is possible for the TV to switch on or off but no picture or sound. This means the input board or tv tuner is faulty in which case you need a good tv repair technician

Sounds like it could be a bad capacitor on the power supply, or possibly on the video out circuit. Bad capacitors are a common problem in Plasma and LCD monitors and T.V.'s.

LG 42 Plasma try's to turn on but just goes back into "stanby" ?


Check to see if you get Va and Vs voltages from the power supply. There should be some wires running to the y-sus. A couple of those wires will be labeled va and vs. Are they present? There will be a sticker stuck to the panel somewhere telling you what they should be.

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.

Samsung spn4235 plasma tv


The set will need some screen voltages adjusted on the power supply board, the VS voltage is marked on the panel inside the set, find the VS test point and the VS adjustment potentiometer. adjust the voltage down at least 10 volts, if your not an experienced person in electronics, get a person that is, there is a high voltage on that board that is dangerous
