51 samsung won't power up

Does the on screen menu work?

not likely as if set was on or powered on later there may not be any usable parts---consider listing it on EBAY?

hi, i have the same problem, with display port cable, sistem not working 100%, any help? thanks in advance and sorry for my english.

If i remember correctly ten blinks means a high voltage error.
The only thing you could try is unplugging the power cord then plug it back in and try turning on the tv. If it still won't turn on try unplugging the power cord for five hours or longer and try again. If it still won't turn on it would be best to find a local repair shop that works on sony tv's and have them repair it for you.

Try a factory reset:

1. Press and hold "Menu" and "Channel+" on the TV. (do not use the remote)
2. Using the other hand, press the Power button.
3. A small screen should appear in the top left part of the screen.
4. Using the remote, select "Memory Recall" and Enter.
5. Power off and reboot the TV and Computer.
6. Run channel auto-scan to regain the picture.

Sounds like you have a convergence problem. If you go into the setup menu of your TV, there should be some settings to adjust the red, green and blue hues and re-position them so each color matches up. If this does not work or if you don't have a menu, your TV *might* have a circuit board with several plastic screws on it. These adjust the picture and it's a very tedious task to re-align each hue correctly.

My projection TV is an older model from 1995, which is probably why it has this circuit board in place of a convergence menu built into the TV.

If adjusting the convergence still doesn't work, you might need to purchase a new convergence chip.

j ai le probleme sur la mienne , cest qu oi la solution

Check video source like DVD Player has power, check connecting cords, cable connections etc.
when TV gives menu on screen that means TV is fine and problem could be hooked video signal items.

your power supply is out
