The dvd player works, but no tv stations. Tried to go to the tuner and auto program to add channels, but will only delete the channels. I can't figure out why the TV picture won't work. Any ideas?
There is a memory IC, a very small one having 8 solder leggs, that stores the channel conditions and all other details of picutre, such color, contrsat, brightness, sharpness etc;. Eventhough it small in size, the function with it when the TV works is great. If this IC ahs got damaged, no memory function will be there. From this memory IC, all data are retrived to the main system IC when we switch ON the set after a switch OFF.
When we switch OFF the set, all data at that time, will passed to this memory IC and will be store there. This is a non-volatile type IC [that is even the power to it is switeched OFF, the data stored in it won't lost. And when power comes, the data stored will be retained from it and passes to the main system control IC to process. I think that I've made an idea to you, about how this IC works and how its damage result in working of the TV.
This IC can be located very near to the system control IC, direltly soldered to the circuit board. You have to replace it with same type and number. Insist on same type and number [the number will be printed on it], as this is a very critical component. Won't cost more thatn $4. It can be purchased from most of the electronic spare part shops at your town.
I think that I've made the problem to your Tv somewhat clear to you.
Don't hesitate to rate this solution. Best of luck.
