    Its an 02. No pulsation, the light comes on and stays on untill I turn it off. The only sounds I hear are standard strartup sounds, no buzzing.

    I have replaced the IC's on a Phillips 47" before, would bad IC's or resistors cause the same prob? About 6 mo. ago someone on here had the same prob. I cant seem to find the conclusion. Can you check that for me? Thx.

    could the bulb be bad, and where would that be located?

    I have no picture or sound. the red power light comes on and stays on until I turn it off. All the green leds are on in the back (1 red and 5 green). The only noise I hear is your standard strartup noises. I have replaced IC's before on another tv, could this cause those cause this prob also? What about pip fuses? Any help would be appreciated. Thx.

First check Pico Fuse 05 they look like resistors but will be Green or Yellow and Check Q777 which is Transistor.
Another thing that can cause this is the STK ICs if everything is on pc05 and Q777 then replace both STK ICs they are big black ICs and will have PN# on them STK392-110s
Mats Electronics has them 1-800-628-1118 also CK RK42 3.3ohm resistor, RK46 1.5 ohm resistor they are near the STK ICs.

    Ok this is Normal for Hitachi for STKs to go bad and will shut TV down. these ICs are Covergence and startup for high voltage you need to replace Both ICs.

LEDs lit in the back? Do you mean CRTs?

    CRT means Cathode Ray tube. The three tubes at the back that project image onto the screen and hence the name CRT rear projection tv. Are these the the ones you meant by "3 LEDs at the back"?

  • eagle338
    eagle338 Dec 01, 2010

    Ok. When the red LED comes on, does it blink or does it stay solid red? If it blinks then how many times does it blink in between each pause. I have a feeling that this is a power supply issue, but just need to confirm.

  • eagle338
    eagle338 Dec 01, 2010

    If it just stays on and does not blink it is definitely a problem in the power supply circuit. I would start by looking for shorted components in the same. How good are your electronics/soldering skills?

  • eagle338
    eagle338 Dec 01, 2010

    Ok. In that case ask them to run a continuity test on all the power supply components(other than capacitors, transformers and coils) and see if any of them are shorted. Let me know what you found.

Hi,

When you turn it on, does the red light sort of pulsate on and off?
Do you hear any odd sounds (a squeal, perhaps, as the red light flashes) coming from inside the set?


How old the unit is?

Let me know,so that we could proceed.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Thanks for your response!!

    This is an internal failure and needs repair. Unfortunately, there is no reset for the same other than getting it repaired. There are few probabilities that you need to inspect.The Hitachi TV are known for having problems with cold solder joints,
    resistors and capacitors in the power supply circuitry of the TV. The TV
    has protective circuitry that when it detects a problem with the
    electronics of the TV will shut at down and will not allow it to be
    turned back on, until the problem is corrected. This is not a DIY
    project since it requires testing the circuitry and soldering in the
    replacement parts. One part can often cause another part to become
    defective. Not replacing all the defective parts will result failure
    very soon. This is not a cheap repair. Most rear projection TV repairs
    will be in the $400 ballpark for cost. Most rear projection TV sets have
    early failure of parts due to heat buildup.Other than the power board, it could be a bad ballast.

    Could be a bad connection , make sure the lamp is all the way in and all wires tight
    could be a bad solder connection on the ballast printed board , may be worth a look at its belly.


    If you wish to repair it yourself, revert and i could provide few pointers.However, in these cases, it is advisable to call a tech as we could get a refund of a part which might not solve the problem.However, you being an home owner, would not able to replace the part if that does not solve the purpose.

    Let me know,if needed further assistance.

    Hope i helped you.

    Thanks for using ' Fixya ' and have a nice day!!

Our 2 draw dishwasher stops mid cycle once or sometimes several times. The red light comes on and it bleeps until we press the start button then it will continues the cycle.


The red light and beeping indicates a fault. The fault code number will be indicated in the display or by other LEDs being lit. If you post back with the details of the display we may be able to help you.

Where light is for controller port four its flashind red and xbox will noy work?


hi, this is what that code is telling you, also do you have a code on the screen when switched on let me know if you do if you dont ill tell you at the end of this post how to get an error code so i can tell you exactly what the problems is.

Section 4 is flashing red
- Hardware Failure
/ \
\ /

The Specific Type of hardware failure can be determined by the error code displayed on the screen.
If the screen is blank or you would like additional information follow the instructions for determining the secondary error code in the section below


here is how to get the secondary code for me.
The specific type of hardware failure can be determined by a "hidden" error code

* Turn the xbox 360 on, and wait till the 1 red lights are flashing.
* Press and hold the sync up button (the small white one), while holding that button press the eject button.
* The LEDs will now blink the first number in the code ( so 1 red light may be lit so write this down).
* Release the eject button and press it again.( it will then change the red lights and maybe 2 will be lit up write this down also)
* The LEDs will now blink the second number of the code.
* Release the eject button and press it again.
* The LEDs will now blink the third number of the code.
* Release the eject button and press it again.
* The LEDs will now blink the forth number of the code.
* Release the eject button and press it again.
* The LEDs will go back to the 1 red flashing lights.

so what you need to do is this, when the 1 red light comes on hold down the little white sync button and keep holding it down all the time, now whilst your holding that little white button down on the front of xbox press the eject button but keep holding the white button down now write how many lights are lit up and this is the 1st number in the code, so keep holding the white button down dont let go of this white button then press and let go of the eject button again and write how many lights are lit up whilst still holding the white button down, now do this 4 times all together and you will end up with something like this written down
4402

once you have this four digit code send me a message back with the code then i can tell you exactly what the problem is and what you can do to try and solve the problem

let me know how you get on or if you need further assistance ok

not a solution but i have a 50gx30b doing something similar, no picture no sound, 3 green leds are lit up on the main board and then one red led lit up also on main board, front panel red led stays on for about 30 -50 seconds and then it all shuts off, I then have to unplug and replug to get the same results.

43FDX15B No picture, Power light stays on


Just a thought, but check all of the pico fuses for a blown fuse. The pico fuses look like a small yellow resistor. Some Hitachi's are famous for having a blown hi-volt ceramic capacitor and a blown pico fuse.
I think the red led on is a short protect indicator, but I could be mistaken.

Hello repko,

This looks like a problem related to your High Voltage Protection circuit. This circuit shuts the TV down when it senses a high current condition (a short in a vital circuit). It may not involve extensive repairs, but it will involve some repair work. I can give you a better diagnosis if you do a few things for me.

1) unplug the TV and take the lower rear panel off
2) look at the back of the panel or in the TV for a chart showing you the diagnostic LEDs
3) Look at see if LED D912 is red or not (this may differ in your model, if so write down the numbers of all the diagnostic LEDs and there condition on or off red or green.
4)post these in a reply to this topic.

Once this is done I'll be able to give you some idea of how extensive this may be.

Thank you,

I hope this helps,
