Hitachi 43fdx no sound no pics has red light NEED YOUR HELP

SOURCE: Pulsating power LED. No picture. No sound

Either the main smoothing capacitor or the voltage regulator are faulty. You may find that the power LED will stay on after pulsating for several minutes, at which time you can switch the TV on.

SOURCE: Hitachi 43FDX01B convergence red line wont move

probably need to replace STK IC on convergence board and possibly associated low value resistor

SOURCE: 53WUX10BA no power/sound/video but power light is on.

With KG02 removed, the short lies in B+ 115 V1.

SOURCE: HITACHI 50UX10B AP23 CHASSIS NO POWER

please check all the lights that are in the chassis hitachi puts led in the chassis so that if one of the lights are not working then u know that circuit is bad. now there is 2 things that hit has wroung in the units and that is a 2kv hv cap of the horiz output transistor that burns up and kill the power supply look for a small black or brown fuse it will not have glass on it it is rt behind the reg ic in the center of the chassis it allwas opens up because of the hv cap doonot run the tv without out that cap it will overload the horiz drive and will burn upo the horiz output but u have a very good ctv ther if u fix it will last u a long time and it is a very easy tv to trouble shoot.

SOURCE: TV Want Power up

This tv have different causes for no power.
Can you tell me if any light on the chassis is off?, if so, let me know the location part number.
Common problem is IC output ( short) or convergence STKs ICs.
Thank you
