Samsung HPS5053X/XAA Distorted picture. Y Main?

[r2digital]

Hello guys. Forgot i had this tv laying under the bed anyway, i plugged it in and this is the picture that i get. What would cause such a crazy distorted picture? I've replaced the X and y Sustain boards along with the X and Y buffer boards(2 years ago), Tv worked fine for about 2 years before it gave out again. also have replaced the logic board and main board recentlywithin in the last year or so. Also the boards tend to make make a very distinct Buzzing noise. With X main and y main plugged in, the noise is pretty loud, generally coming from a tiny transformer on the Y MAIN. Not sure if thats an indication that the Y main has died again? Any help on this is greatly appreciated, thank you

This is probably a main board problem. I know you replaced it but replacement parts can still be faulty.
To confirm it you can follow the steps indicated here:

I did all that, all i get is a white screen now. Any idea what that indicates?

The pattern should change after a few seconds, does it? And it'll cycle through each test pattern, like this:

nope, i waited about 60 seconds, still stays completely white.

May be different on this older model. I guess on full white it's hard to see the pattern?
Did you remove the LVDS?

If this does not work the test patterns may be available from the service menu.

LVDS is unplugged completely. I can give it a shot from the service menu. I read somewhere if i installed the wrong mainboard IE version B instead of version A that it originally came from

I can't seem to access any of the menus on the tv. Any idea what the issue may be ?

Some Samsung TVs require an input to let you access the menus.
Try powering off TV into standby, then press (on remote) Mute, 1, 8, 2, Power.
Service menu should appear once set boots.

wtf??? I put it into service mode and now everything works fine?????

Sounds like the main board has a problem, perhaps intermittent and coincidental with accessing said menu.

I also swapped the logic board and mainboard( I had purchased new ones of each in the past) and vice versa to accessing the service menu. One of them was defective i forget which one. But all is well. Everything is working have had direct tv running for about an hour now in 1080p

Well, enjoy... I'm not sure if it'll last though.
