Vizio xvt553sv main board no hdmi input...

[weezies_view]

Hi there everyone... OK, so I initially had a Vizio 55 inch led TV that went out on me. Model number xvt553sv. No power, completely dead... my first initial thought was replace the power supply board... bought one off eBay for 50 bucks and replaced it... powered right up and went through updating section and went into Vizio screen and turned on... thought it was working properly till I noticed all the hdmi inputs were not working... so I went to the main board and checked all the fuses... about 6 or so fused totaled and they all work working properly.. checked on this forum and found some people with same issue but was never really able to solve the problem without paying 160 bucks to replace the whole main board. What I found out was that all power was being cut off right where the hdmi processor was... so that has to be replaced. Now I jus need to know where I can get an hdmi processor for this board number 3655-0122-0150... I have experience in surface mount soldering so this will not be an issue for me to take it off and put new one in... I jus need to know where I can get one...

Re: Vizio xvt553sv main board no hdmi input...

My XVT323SV shows No HDMI, No Bluetooth address, NO wireless and on setup it won't show any HDMI inputs(only shows antenna, AV and RBG). It won't show any devices(Kind or brand). I can only use coax, av and maybe rgb inputs.

Is your tv showing any of my symptoms besides no HDMI inputs?
