I have a WS65711 - 3 months ago I replaced the Convergence - Today the TV was on then turned itself off. I have tried to turn on but it just turns off after 30 seconds

Did you do the diagnostic self check:

when green power light goes off on the front of the set press and hold both Menu and Input(Device) buttons for 5 seconds and release both.

Power light will blink two digit error code like: 2 pause, 2 and repeat it at least 5 times.

Let me know what code you find and I will try to help you.

TV turns on, then turns itself off about 2 seconds later.

set has a self diagnostic---after set does shut down press and hold MENU AND DEVICE(INPUT) buttons on front of set for 5 seconds----if 2 blinks, a pause and 2 more blinks: this is short protection error code---The set does use 2 Stk394-250 and each is protected by a pico fuse in the power supply---if either fuse is blown the set will shut down(it detects no voltage or missing voltage;) It is not uncommon for a shorted IC to cause this problem; if you locate the STK's look carefully at the resistors around them---if any are discolored or burnt---you have found your problem.

No Picture

Did you have color problems in past? Most of these sets have convergence problems. Amps goes out. But you should have seen some type of distortion from color, red,blue, green. If no color problems then maybe vertical ouput out or horizontal output bad.

Ghost images on tv

Bod convergence IC's. Try doing a reset of the TV first by pressing and holding the ACTION and POWER buttons while the set is on. A CHK screen with diagnosis will come up in about 5 seconds. Once that happens release the buttons and shut the set off and then turn it back on. If problem still is there then convergence circuit problems need to be fixed.
