Check all high voltage caps with Mfs less than 10 . For example a 160 volt 2.2 cap or 200 volt 1 Mf or 250 volt at 4.7Mf etc. Always substittute with a higher dgree cap. Like an 85 degree cap to a 105 cap! And be sure you always have good solid grounds on anything with heat sinks, transistors. mosfets,vertical,powerline regs etc. Thanks for asking!

My tv when turned on goes to a black screen with 3 color strips of lines going across the picture then goes to a snowy picture but only shows on half the screen and then shuts off

This sounds like a vertical problem. It could be just a bad solder joint or it could be a IC that has failed and surrounding componets. Hope this is helpful.

I have problems with this 27pt5445/37 philips tv when I turn on the screen with vertical problems and within seconds it turns off and replace some capacitors and no improvement

Did you replace cap 2465, 100volt 10Mf to cure the vertical problem? and You may still have a bad cap at location 2415, 160 or 200volt 2.2 at 85 degrees. Check this out! When the tv tries to come on does it make a very good effort with the picture tube cracklin on and then shuts down? If this is true you may need a mosfet, located at 7404. Part# 934054713215. Good Luck! This is a smd!
