I have a Vizio 65in TV model E650 B2. It will not power on. I have replaced the main power board.


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Diagram emachine wiring


There is no specific wiring for eMachine. your wiring goes from power supply (big box with fan) to motherboard (large board with many components) to hard drive, cd rom, fan, etc. pretty easy to figure out if you look closely

The picture is clear but the colours are distorted like a sort of heat sensor is on the figures. Images of green and purple like shadows on the people in the picture


Are you using the component input. This is 3 wire video. If all 3 wires are not connected color will be off. This is very common. Cable may also be bad. How does the tv menu look? Press menu on tv or LG remote. Is picture bad on all inputs?You need to determine if problem is the source or the tv set by trying various video sources and inputs. If the tv is at fault but the tv menu is ok I would suspect the main board. If the the menu is also bad i would suspect the t conn board.

F-20 has sound but no picture, on VGA, or TV cables. Power looks ok. where can i find more info on testing for the problem and fixing. Thanks


Sound but no picture usually implies a faulty backlight. It may be simple case of replacing one or more electrolytic capacitors in the power supply or on the backlight inverter board. It may be that one or more inverter transformers has gone open circuit or short circuit, causing the inverter board to shut down. If this is the case then you can replace the inverter board with a universal inverter board but you will need to figure out the wiring. In most cases there are only three wires required - 12V, 0V and switching wire.

so you are saying the fan was hard wired to a nokia charger ? WOW... if you can't figure out how to rewire it then I guess you already know the controller board has to be replaced.

I am trying to install a new convergence board on my rca d52w19 tv. I cannot figure out where a couple of the wires go. Can you assist me on this.


if you are putting in the whole board, you just have to unplug everything off the pld board, then there should be 4 screws holding it in, if you are doing the convergence IC's (there little black chipd, with about 20 wires on it), you will need 2 of them, and you have to turn the boart over, and unsolder the old ones, and solder the new ones, not an easy task, but not real hard eather, thats why service centers charge about 5 hundi to do it
