Question about Hitachi 51SWX20B 51" Rear Projection Television
Hitachi m# 51swx20b
dont know if happend by qoincidence but i used my cell phone for a light to hook up some cables for dvd and at the same time heard a clicking sound and now no pic have power .
The diode led / diode GREEN is flahing d967 - d940 TOWARDS FRONT OF SCREEN ON CURCUIT BOARD its the middle boars of the 3 . and the same for the RED led / diode d912 - d915. this one next to I902 located in the back of the board.
is this a simple replace these 2 parts or just a where to trace down warning o\f some kind?

It's possible that the Convergence IC's are causing a shutdown of the power supply. Also on this model, there have been problems with: C707 - 1000pf @ 2kv Cermaic Disc Cap (normally a small blue one) Hitachi Part # 0244211. I901 - A STRM6811a Reg Ic and E994 - 2.0 Amp Circuit Protector (Pico Fuse) having a high failure rate. If the 2 amp pico fuse was good, and the capacitor looked OK, then I would check the convergence circuit board. There are many other parts that can also cause shutdown problems, however.

I would check for burnt resistors as the 150s are interchangeable with the 110s however in alot of hitachis I have seen resistors blow after upgradeing to the higher wattage ICs. I Usually switch out the convergence resistors whenever I go to a higher wattage IC just to be sure. If you need more help let me know.

C603 is a polyestor capacitor 0.068UF-FEB 50V part number 0880047R S901 is the power relay ALKS329 the part number for the relay is FJ00142 . I recomend checking the pins on the ICs to make sure they are not bridged. If you need more assistance let me know. Vance Baldwin should have the parts if not you may have to order through hitachi

Over the years of servicing these sets and others for Convergence issues, I have on several times gotten defective Convergence ICs. In your case where a Resistor is now open, (Probably a 1.5 ohm 1/2 watt), I would suspect you had gotten a hold of a defective IC. I would replace them both again. Make sure to use Heat Sink Compound between the ICs and Heat Sink.(Just a thin coating on the metal area) You can get the heat sink compound from Radio Shack. They should also have the Resistor you need.
