Question about Sharp 32F640 32" TV
I have a Sharp 32F640 32" TV that works beautifully when it works. Sometimes when turning it on, it attempts to turn on but will not. We can unplug it for a period of time and try turning it on again. Sometimes it will then turn on and sometimes it will not. We live at the beach. Could the moisture or salt in the air be causing this? If so, what can I do to fix it and stop it from occurring?
The easiest thing to check is for loose conections because the unit is intermitant,the chassis should be check out for overheated areas and cracked solder joints in the power supply,horizontal driver and all the diodes and resistor off the secondary of the output trnasformer(flyback),if you are familiar with tv service this will help but if you are not too familiar be safe and call for assistance form a servicer.No doubt humidity can damage anything with time.
