Question about Sansui 32" TV

My Sansui 32 Inch LCD screen shuts off, after a minute. The power remains on - the screen just switches off.

I have switched the main power off and back on - the screen still remains off. After about half an hour I switch the TV back on it works for a minute and then the screen switches back off.

This may not work but i had a similar problem. My 32inch sansui LCD TV would switch off after about 10-20 minutes. I had to unplug it to get it going again. So i decided to open it as the warranty was long gone anyway. Very easy to open the back. I checked to see if anything was "swollen" as some sights suggested, but found nothing burnt , blown or swollen. Then i thought about heat? So i left in on without putting the metal backing plate back. It worked! when i put the plate back.....20 minutes and it shut down. So i just left the metal backing plate off! And no its not dangerous as the sansui has a protective plastic backing, that covers the metal one, that is better ventilated and protects the bits and pieces. Its been a week now and its fine.

Hello
Either your Sansui TVs screen voltage has gone very low, or its brightness control section inside its chroma IC has damaged. To make sure which is faulty, you have to open your tv. There is an LOT [Line Output Transformer], which can be locted on the main board of your TV, from which three wires will go to the picture tube, out of which one will be connected directly to the picture tubes upper side, look like as it is sucked by a rubber ******. Usually this component is balck in colour and will have two adjustment controls integrated with it, marked as "screen and focus". After switch on your TV, just adjust the "Screen" control preset a little clockwise to see whether there is any advance in the bright ness of the picture. If the focus voltage is less or its wire connection to the picture tube base socket gets corroid; this type of fault may occur also. Check that also. If these does not help you, the chroma IC has damaged, and should be replaced with same type and number. OK.

A couple of options. First and cheapest, you could turn off the monitor. Second, for about thirty to fifty dollars, you can pick up an energy saving surge protector. With this, it has a main plug, and switched plugs. The switched plugs cut power when the main item is turned off. I.E. PC turned off, monitor, speakers, printer all turn off a moment later.

You may need to enable the notebook VGA output. They can switch between notebook only, notebook + VGA or VGA only. You usually press the "fn" key and one of the Function keys at the same time. On my laptop, I press "Fn" and "F5". Please note that it can take some seconds for the switching to be completed so press them together once and then wait 10 seconds to see if it does what you want. (remember it may be something other than F5, look for a picture of a monitor or a square symbol).

Sansui LCDTV 40 inch goes Off automatically


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.

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.
