Re: The HDMI connector broke loose from its mounting...
Hi there, you can just re solder the points onto the board once more without buying a completely new board. just remove the board and solder the contact point back on the board itself.that should fix it up for ya. thx for using fixya:)

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
I would also just buy a new board .BUT keep the old board for parts! This way if anything goes out you can compare components on the board etc and figure out what's wrong and also use the parts for repairs when you need them. Some of those boards HDMI ports have the tiniest solder joints and you can easily bridge them make the board useless anyway. These things are way more fragile than the old CRT tv's. Just be a little more careful next time.
Its part of the tuner in most cases and not real easy to replace for a novice---sometimes the tuner will have to be replaced as when it broke off it may have damaged the circuit board inside the tuner.
there is a possible way around this: With a box of any kind being used that has the Audio/video jacks for output of signal you run cables from them to a set of matching inputs on the rear of set, leave set on that input and change channels with the box--bypass the tuner completely.
If the tuner and board it is only sold as a complete unit it will be expensive to repair.
The most likely explanation is that you have strained/damaged the connecting board or cable end at the rear, or less likely a cable has come loose inside.
If it s getting it's feed from a cable at the rear hold the tv perfectly still and move ONLY the cables concerned one at a time. It may just need a new cable or plug if not...
Try prodding / tapping around to see if you can localise it further. Either way you will probably need to dismantle if all connections are ok.
I hope you didn't use screws that were too long when it was wall mounted as that may have damaged a circuit board or cable inside it
HDMI is not a module. It is part of the small signal circuit board on most of these TVs. If it has an separate HDMI connector board (inside the cover), this is the most likely cause of the fault as a broken connector is 70% of all HDMI failures. There is still over a thousand volts inside one of these flat panel sets. Be very careful not to void your OWN warranty... You can order the part from Sony, BUT, you should know what you are doing. Just picking up the circuit board wrong can blow the board out before you even get to use it...
This problem will have to be taken or shipped in to a service center for repair or replacement of the cable connector on the main board. The telephone number for Insignia customer support is 1-877-467-4289. and the website is www.insignia-products.com. You can also call the Best Buy customer support telephone number. 1-888-237-8289. Give them you make and model number of television and the problem you had with the broken cable connection.They will be able to tell you how you can get service for your television. I hope this information helps you with your problem.
It is possible for the HDMI connector to be re-soldered back on. However as the pin connections are small & delicate it is possible that some of the pads on the board may have been damaged, if this is the case then a new board would be required.
