My 50v710 will not power up at all. it does not even go into the diagnostic mode to give me a code thru the led's on the front. The bulb is good and the two safty switchs that are behind the bulb and at the bulb replacmrnt panel are depressed. All fuses look good and I see no signs of burnt or leaking parts. I am getting power too the first power board but nothing from the brown and white wires running to the smaller board that connects to the ballast board any ideas or does anyone know where to get a service manual for this that I dont have too pay for. I just had a son so money is tight I cant afford 9.99 hell I cant afford .99 thanks for any help

Oh boy, you are in for a learning curve. I spent the better part of a year getting to know the Nissan system of computer controls, diagnostic procedures, everything about Sentras from the mid eighties to the mid nineties. Your Stanza is very similar, fortunate for you to have a '92 with somewhat more sophisticated controls than my primitive '87 model. I even had to deal with a computer controlled carburetor-more headaches than I care to recall.

First, Jack, you have to find the computer, which is the diagnostic unit and the little LED light or lights on it are the blinkers that blink out the trouble codes. The computer on mine is under the passenger front seat. If not there, it will be behind the glove box or in the center console. So you locate it and set it in mode 4- for code read outs. That is the diagnostic mode. There are 5 modes, you can read the short paragraph about it in the link I will give. It's really easy, there are only 16 codes in all. Here is the link with all details and short description of codes.

did you hear any sounds from the tv..?or any some like problem occur before the tv does not switch on.?

A blinking yellow for this model indicates the TV is too hot, unplug & allow 30-45 min to cool before re-plugging .
OR: lamp not installed or lamp door not closed. there is a lamp door switch that may not be closing, simulating door not closed

LED Indications

The front panel Status LED provides an indication of

the set's operation and the possible cause of a malfunction.

If an abnormal condition is indicated, perform the

Self Diagnostics procedure.

Self Diagnostics

To activate, press the front panel <ACTIVITY> &<CH

??> buttons at the same time and hold for 5 seconds.

The STATUS LED will then flash denoting a two digit

code.

• The number of flashes indicates the value of the

MSD (tens digit) of the Error Code.

• The flashing then pauses for approximately 1/2

second.

• The LED then flashes indicating the value of the

(ones digit) of the Error Code.

• The Error Code is repeated a total of 5 times.

Example: If the Error Code is "23", the LED

will flash two times, pause, and then flash three

times.

Table 2-2: LED Indications

Error Codes, descriiptions and the most likely cause of

the error are listed in Table 2-3.

Note: The TV must be in "Shut Down." The LED

will probably be indicating an abnormal

condition. If the TV is switched Off, AC is

removed, or a System Reset is performed, the

code automatically resets to "12" No Error.

See the Error Code Log to retrieve a history of

errors.

Note: Use the front panel buttons, not the remote

control.

Note: If there is no response, the front panel may be

locked by a V-Chip setting. To unlock, press

and hold <ACTIVITY> on the front panel for

8 seconds.

LED Indication Condition

Off Off (standby)

Green Power On

Slow Blink Green Power Off with Timer Set

Fast Blink Green (80 seconds) > Off Power Off (Cooling fan still working, 80 sec)

LED Indication Condition

Red Lamp Failure

Yellow TV Too Hot

Slow Blink Red TV May Require Service

Slow Blink Yellow Lamp Door Open or No Lamp Installed

NORMAL INDICATIONS
ABNORMAL INDICATIONS (For details perform Self Diagnostics Procedure.)

It would either give you a an error code like F1 or the unit would have no power going to the control unit and you would have no led's lit up on the control itself. If you have any further questions message me back you can also put your unit into diagnostic test mode by clicking this link which tells how to acess the diagnostic menu http://www.ehow.com/how_5545508_access-error-codes-ge-washers.html I await your reply If you have any further questions Thanks Rick

the display will sequence to the next code
logged. The last code being displayed being
the oldest code. The up arrow will sequence
up the list one code each time it is pushed
until it reaches the top code. If there are no
diagnostic codes available, ‘00‘ will be
displayed for the diagnostic code.
There will be no multiple occurrences of
either a diagnostic code or help code generated
in the same cycle reported on the list.
But if the same code occurs in repeated
cycles, it will be registered.
To clear the diagnostic code list press
wrinkle prevent and very dry (>) for 5
seconds while viewing the list.
System Check Mode
While in diagnostic mode, pressing the damp
dry and signal (+) keys for 2 seconds, will
put the dryer into the system check mode.

This mode will allow the various inputs and
outputs to be controlled and viewed by the
technician by pressing individual keys. If no
activity is seen for 5 minutes after a key is
depressed, the control will reset back to the
normal mode. If no further activity is seen
after an additional 5 minutes the washer will
turn off. The following table lists the various
functions based upon on keys being depressed.
Membrane Pad Check

All of these tv's are board replacement only the individual parts are not available. The boards can cost anywhere form $200 - $400 each. Even if you do it yourself it is still an expense, if you get the blink code i can point you to the correct board. These sets have different boards even within the same model range. One of the first diagnostics is does the back light come on, if not then you either have a balancer error or a bad bulb in the panel. Why i suggest this is because it is the most common problem. If it is the bulb in the panel you have to replace the whole panel, the bulbs are not available as an individual part.

Have you check the power supply,that's what it seems to me.

With both LED's flashing sounds like a bad lamp to me. Not uncommon for Hitachis LCD projections to have that symptom. Cjeck your owners manual for the light flash code. Good luck..

Please put back lamp (bulb) cover properly and check as lamp cover is open/ not fixed or improper fix is also cause of LED flashing.
