The color on my 32 inch sansui flat screen is xray like dark.
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.
