1 Answer

Hitachi 61UDX10B My tv will not turn on it just blinks a red light on front and has a clicking noise with it. No picture and no sound. I have unpluged the cord and that still has not solved the problem. Is there a reset button on it somewhere. hitachi 61UDX10B replaced stk392-110 with stk392-150 went to do a manual DCAM.after a few minutes trying to do the manual DCAM tv shut off red blinking light on front panel and 1 red light on in the back of the middle internal board and 2 green blinking lights and 1 green light thats on. all on the same middle board.

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.

Check the resistors near the Ics especially the 3.9 ohm 1 watt resistors often one or two will be open then when you install the higher wattage Ics which run cooler you can actually wipe out all the convergence resistors which are 3.9 2.7 and 4.7 ohm 1 watt resistors

Hi,
TV needs lamp replacement as existing lamp got weak or has been reached to end of its working life, please note that lamp is not dead or broken so that is why lamp lit is not lit at tv front.
Hope these info will help you.
Thanks.

Hitachi 51UWX20B no sound, no picture, blinking green LED


The 392-150 is a higher current device then the 110---you can use either--this is normal in the hitachi sets---I usually replace both with 150's---check the led that does not light---should indicate which voltage source is bad---if it is one of the 2 voltages for the convergence ic's(one is a positive and the other a negative voltage) then the convergence Ic's may be bad---look for any discolored resistors around the ic's---one way to tell if it is a convergence ic is to de-solder both ic's and see if the set turns on(the convergence will be out the window) but if it comes on change both and do the alignments with the Hitachi remote. By the way----the led should have a location number printed on the top of the circuit board.

TV SHUT OFF WHILE WATCHING. UNPLUG AND THEN PLUGED BACK IN. RED LIGHT CAME ON IN FRONT FOR A SECOND AND WENT BACK OFF. TV WILL NOT COME ON.


power in the tv has nothing related with the DVD. The tv has to have raster (white screen) even without signal (cable, DVD, others) if the tv alone is just having the led flashing and neither sound nor video (black screen) The tv has a short circuit in some of the boards that are part of the tv system. the blinking is part of a protection when the tv was created in the factory. Refer to the technician to repair this problem.

Hitachi 53uwx10ba turns on & off when off red flashing light/clic


Same problem. Replaced both convergence ICs about 5 months ago. Worked fince since then and just recently no sound, no video, blinking red on front panel and clicking sound. I suspect that the ICs went bad again and blew a resistor or two. I used cheap Chinese ICs instead of the Sanyo ones and thing this is why. I'll be looking at it again and post solution.

Replace Both of your STK ICs they are your convergence ics they are big black ICs will have Part# on them for example STK392-110, if they are 110s use 180s, if 020s use 040s other wise replace with exact same number. To get Parts call Electronix 1-800-223-3205

Flashing LED
<< Back to Quick Fixes Page
If your set all of a sudden won't come on, e.g., the screen is blank, but the LED on the under the screen next to the on/off switch keeps flashing, then there may be an internal fault on the set that needs to be reset.
To force the reset, try this:
  • Unplug the set and wait a few seconds
  • Replug and see if the video returns
Whenever the set senses an internal fault through its monitoring circuitry, it essentially shuts down the set. The flashing LED provides the indication that a fault has been detected. Removing power to the set resets the monitoring circuitry. When plugged back in, the circuitry again does a check of the system. If it finds that there truly is a problem, then the set is shut down and the LED will again flash.
