Rheem classic quiet 80 it has two green light. one is indicate power on. and other is blinking 5 times and 2 second pause. then repeating this cylce like it forever. I have take the pcb out from the furnace , for seeing if there any electronic parts are burning or some cracking, but I don't see any thing unusual. this problem occured when the water heater is leacking water from the pipe then the water was spraying over the funace. because the funace is locate just one foot away from the water heater.

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.)

The blinking should be in a pattern.

Power Green On (S0) Computer on
Power Green 1 blink every 2 seconds (S1) Suspend Mode
Power Green 1 blink every 2 seconds (S3) Suspend to RAM
Power Green Off (S4) Suspend to Disk (if applicable)
Power Clear Off (S5) Computer off
Power Red 1 blink followed by 2-second
pause - Repeat
Power Supply failure
Power Red* 2 blinks 1 second apart CPU thermal shutdown
Power Red* 3 blinks 1 second apart CPU not installed
Power Red* 4 blinks 1 second apart Power supply overload (crow bar)
Power Red* 5 blinks 1 second apart No memory
Power Red* 6 blinks 1 second apart No graphics
Power Red* 7 blinks 1 second apart System board failure (detected prior to video)
Power Red* 8 blinks 1 second apart Invalid ROM
Hard Drive Green Blinking Hard drive activity
*Blinking

The model indicated has a self check feature.

If turned on and green power light comes on and a few seconds later goes out:

On front of set press and hold both the menu and input(device) buttons at the same time for at least 5 seconds and release both.

Power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it for a total of 5 times.

Let me know what error code you find.

If you unplugged the set--you will have to plug it back and attempt to turn it on--unplugging set clears the error buffer.

ok, a model number would be helpful but:

when set turns off and green power light goes out: on the front of the set press and hold both the menu and input (device) buttons at the same time for at least five seconds and let both go.

Power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it for a total of 5 times.

This is the error code and indicates where the problem may be---let me know what code you find and I will tell you what it means.

That model does not have a red light---Green.

If set powers up for a few seconds (green power light) and goes out do the self check the model indicated has:

On front of set (not with remote) press and hold both the input and menu buttons for at least 5 seconds and release both.

Green power light will blink a two digit error code like 2 blinks, 2 blinks a pause and repeat it several times.

Let me know what error code you find (if you have unplugged the set that will clear all errors and you have to plug it in and try to turn set on again---when it fails do the self check)

ONE OF TWO THINGS HERE:

set turns on and green power light goes off in a few seconds, if this is the case on the front of set push and hold both menu and input buttons at same time for at least 5 seconds and release both buttons.

Green power light will blink two digit error code like: 2 blinks, 2 blinks----a pause and it will repeat error code for a total of 5 times.

If this is case let me know error code.

If green power light does not come on let me know.

You answer will dictate a response if you let me know here.

I am expert on Mitsubishi sets and know them well.

I have this same POS model. It is not the thermostat. this model is just garbage and cant wait to get something that works right. i have been fighting this thing for 4+ years now.

Try this and let me know what you find:


Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and two blinks--this is the most common and easiest to fix.

if your set does not have a device button press Menu and Input together for 5 seconds and release. there will be a pause between blinks---2 blinks, a pause and two more blinks etc.
