How to troubleshoot Samsung plasma tv power supply

Relays on the power supply are clicking on and off numerous times, but it is hit or miss, meaning that it does not happen every time i plug the tv in. Also, there is no audio from the speakers, only from the headphone jack. Two capacitors have been replaced previously and none of the remaining caps appear to be bad. All fuses are good and there is proper voltage to the power supply. Checked voltage on all of the other panel connections(Vs, Vg, Va) and all appear to be as labeled. Just wondering where to go from here? Where to look next? Any assistance or nudge in any direction would be greatly appreciated.

If relays are clicking, the problem could also be the diode connected to the relay or its own power supply. Check whether the relay is getting power enough to remain activated. This chattering can also be caused due to relays becoming weak or by short circuits on its load.

I don't know about replacing a jack but BN94-01208C fits LNT1953HX is the main pcb that has all of the av inputs on it and it is a snap to change.

Since no brand etc listed here

Google the model number with 2 blinks and look at the results, you may find on another forum the answer to what it means and even a answer--error codes tend to be general in nature so do not expect it to point to a specific part.

Panasonic CT32SF wont turn on


Dont know spec of this model but if it has a CRT (glass tube) display rather than a LCD one, clicking at switch on is idicative of a power supply overload which, 99 times out of a hundred on a CRT telly is down to a fault in the power supply itself or the line output stage (the bit that generates the very high voltages in CRT tellys and also makes the picture scan left to right).
In short, not a DIY fix - take it to a repair shop.

Sony Big Screen TV Not Powering On


This looks like a problem with the High Voltage or switching power supply section of the TV set. What you need to do is to measure the voltage from the HV transformer to the Anodes of the CRTs with a high voltage probe, and check the voltage output of the switching power supply. What may have happened is a component may have shorted out causing an over-current condition with is triggering the shutdown circuit (These are the relays you are hearing). I would check the Horizontal Output transistor, and the components in that section of the TV.

In addition check the voltage test points on the HV / Horizontal and switching power supply board. This will determine if the section is working or not (most likely not). Make sure you have a schematic, and multimeter and a high voltage probe.
I hope this helps,
Thank you,
