I have an X7000 Lightning source de stryker, but only display standby, dont turn light, somebody can helpme
Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Well you did start out good, thats cool, now we have to define focus, Is ir blurry around the edges as well as the whole Picture? If it is, it could be the picture tube, A bad solder connection on the tube socket, and yes it could also be the flyback transformer.

if it is relay problem you can make it direct just to check.check power supply output. as you say that eht ok than it due to stand by section of system control mcrpssr.
SOURCE: Power supply fault?
Check all electrolitic capacitors at power supply area : better replace them.

There should be a small valued cap in the primary side (22ufd?) at 250V. Check that. Also, look for other small caps int he range of 2.2ufd with 200V ratings in the same general area.

.01 mf 2000 volt. in flyback circuit .it is a timing capacitor. the red high voltage block is bad and that took out the capacitor. also check the horizontal output transistor...it is probably shorted.
