Most likely "AV Mode" button(has orange circle on it) on the remote has been put on wrong setting push repeatedly untill corrct setting is reached, I believe it will say "normal" or "standard" Hope this helps.

after turning TV on try pressing guie or menu to see if that makes picture come on.

Check on the back of the TV to see if you have a "remote in" port. It will look the same as a 3.5mm headphone jack. Unplug the TV and plug a pair of headphone into the port and then remove it. Do this several times to breakup any debris that may have gotten into it or corrosion that may have occurred in the port. If something is in the port it will disable the standard remote sensor on the TV.

Sounds like the problem could be in the power supply of the TV. Have a technican check for defective capacitors if you're not equipped to do the job yourself.

Remove the actual stand (4 bolts are hidden in a sunken down spot for them on the back of the tv.

Once the stand is out of the tv, look down to where the swivel joint is at, you should see 4 screws that are going towards the bottom of the stand, those will be the loose screws.

I just fixed mine.

The main board is having issues as that would account for the different symptoms. You should be able to get a replacement main board from www.tvrepairworld.com

The set has a problem that is likely power related===consider having a shop or a tech look at it---cannot wish it away, someone will have to open and check things to even have a chance to fix this.

You are in the wrong aspect ratio, either press the ratio button on the remote control (if you have this type), or go into the main menu & select the picture mode, then toggle over to aspect & adjust for a different size of picture. It looks like you are currently in the zoom size

I would have the power supply caps checked first. If the power supply checks ok, I would suspect a main board failure.
