Good Day, Gil;
Your problem is in deflection circuit (115+v) check these: FP05, DP15, Q777, QH01, TH01, T701, etc. BUT suspect C707 1k pfd, 2kv, and check all the pico fuses (brown) 2" to the right of cap. Good Luck, big IRISH.

SOURCE: No Picture & No sound. Red LED, Green LED, Red LED.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

SOURCE: Dynex DX-PDP42-09 Won't power up.

The main board is faulty. This is the common problem to most of the dynex TVs. As you know there is no repair to this board. Replace it as card basis is the only remedy to this fault.

gopakumarg43_84.jpg Replace this board, rather than making surgery to it and wasting your precious time and money. The cost of the board come around $95. OK.

Vizio d55u-d1 power light comes on then fades off. No sound or picture. Replaced power supply board, nothing still.

Chances are you have a main board issue, you should have run some voltage tests before replacing the power board, its sad how many people order boards that aren't bad because they don't do the necessary testing prior to ordering boards.

I have a Vizio D50u-D1 and the picture flickers and seems to push the picture on top of the current picture. I have a video of the screen if that helps

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size./

Power Shutting Off on Vizio D50U-D1

Start with the power supply board first. That usually fixes the problem. No need tor the T-con board.
