Having problems with your NEC /5V 073-20674-14.5A Rev51 VXi VRM (07320674145A) ?

The tv i bought at a garage sale it was working when i got it. I took it home and pluged it in and now it wont come on, it sounds like it is on and the little green standby light is on but shows nothing and no sound.


Answers :

Un-plug the TV, wait at least 30 seconds, now turn it on again and close your ear to the back of the TV while turning it on, pay attention on hearing a hogh pitching sound coming from the back of the TV, the sound may be quick and go from a lower frequency to a higher frequency really quick if this sound is present then it means the switching power supply. if you don't hear any noises then the power supply is bad. It could also be a bad horizontal driver transistor, it depends on the model TV you got.
