Re: Vizio e550vl HDMI Problems

I took a chance and bought another main board part #3655-0152-0150 (4G), the board in my TV is a 3655-0152-0150 (4A). With the original board installed as soon as I plug the power cord in you can here a click on the power board, the TV will power on and everything works except the HDMI.

With #3655-0152-0150 (4G) installed there is no click on the power board, the VIZIO light on the front of the screen does go to orange but the TV will not power on.

I thought I may have made a bad connection with the ribbon cables or...

Opened it up and took a couple pictures then closed it back up to watch the football games thru the AV cables. Could not see anything obvious around the chip. Lifted the board and looked at the back and the board looked good....

Re: Vizio e550vl HDMI Problems

Took the back off today, nothing obvious sticking out. The part # on the board is [B]3655-0152-0150 (4A[/B]) other numbers are OKM502A4V01904A AND CSD:3655-0152-0395. I found a board with part#[B] 3655-0152-0150 (4G[/B]). Does anyone know if the (4G) is just a revision and will it work as a replacement to the (4A)?Re: Vizio e550vl HDMI Problems

Re: Vizio e550vl HDMI Problems

Did the factory reset a couple times, what started out as an intermittent problem with the HDMI seems to be permanent now. Have it hooked up thru the AV cables until I get time to open it up.

Thanks, will open it up and take check it out today.

Re: Vizio e550vl HDMI Problems

Any suggestions on this? None of the HDMI's are working now. Have the Direct TV HD DVR hooked up thru the A/V cables now and TV is working fine except for the fact it is in 480p.

This TV has 3 HDMI ports, from what I seen on another thread these are basically routed thru one processor. Before I spend the money on a board has anyone else experienced this problem?

I have a Vizio e550vl that up until a few nights ago was working perfectly. Woke up one morning and when I turned it on it was showing no signal on the screen. It is plugged into a surge protector, there were no electrical storms in the area when the problem occured either.
It is connected to a Direct TV HD DVR, a Blu-ray and an audio receiver. Tried resetting the DVR numerous times to no avail, tried the Blu-ray which would not play thru the HDMI either. Swapped HDMI cables around with known good cables, swapped ports, turned TV on and off numerous times and finally the picture came back...
