Having same prob with my soyo, 4 months old. it will just go blank after at any time. sometimes stays on for hours, sometimes cuts off every ten minutes. only 'work around' i've found is to disconnect/reconnect power cable because the remote and buttons on tv will not do anything after tv shuts itself down.

Turn tv on watch it for 20 mins. screen shuts off but green power light is still on. turn it off manualy wait a few mins. turn back on watch for anouther 20 mins or so then screen shuts off again


The reasion your set is shutting off is because the power supply is dieding, and you need to replace the electrolytic caps on the power supply, or purchase a new one, go to www.partstore.com sand check to see if they have your power supply.

It turns on, runs for approx 20 mins then shuts off. when you turn it back on it shuts off in approx 12 min and so on and so on. is this a bad power supply?


possibly, it sounds like there is a capacitor in the power supply not holding charge anymore. Or it is loosing hold of the charge once it gets warm.

Hi I have Prima lv 3228p tv and there is no volume it was working fine yesterday andtoday no volume


prima lv-3228p lcd tv-after 15 mins of play the screen goes funny and there is still volume but the remote will not function. you cannot even shut the unit off, only by disconnecting the power supply. If you wait 15 -20 mins and plug the unit back in it will work for approx 15 mins again- then it will start acting up again?/

This is most certainly a capacitor in the power supply that has gone low in value, hence a low startup supply rail voltage. I would be looking in this area. Tell tail signs of faulty capacitors are from their tops bulging up with possible brown liquid discharge, or if their plastic base inserts give first with the pressure, these pop out from the can.

My plasma turns itself off for about 10 20 mins


It seems that your unit has some sort of Thermal PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. After it shuts down and the faulty component(s) cool down, it restarts again until it once again goes critical and shuts down again only to repeat the cyle.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.
