Re:
There are different rates at which the status light will blink to indicate various errors.

They are listed inside the front panel of the main unit. LED CODE
EACH OF THE FOLLOWING STATUS CODES IS A TWO DIGIT NUMBER WITH THE FIRST DIGIT DETERMINED BY THE NUMBER OF SHORT FLASHES AND THE SECOND DIGIT BY THE NUMBER OF LONG FLASHES. STATUS
11 NO PREVIOUS CODE - Stored status code is erased automatically after 72 hours. On RED LED boards stored status codes can also be erased when power (115 VAC or 24 VAC) to control is interrupted. 12 BLOWER ON AFTER POWER UP (115 VAC or 24 VAC) -Blower runs for 90 seconds, if unit is powered up during a call for heat (R-W closed) or R-W opens during blower on-delay. 13 LIMIT CIRCUIT LOCKOUT - Lockout occurs if the limit or flame rollout switch is open longer than 3 minutes. - Control will auto reset after three hours. - Refer to #33. 14 IGNITION LOCKOUT - Control will auto-reset after three hours. Refer to #34. 21 GAS HEATING LOCKOUT - Control will NOT auto reset. Check for: - Mis-wired gas valve -Defective control (valve relay) 22 ABNORMAL FLAME-PROVING SIGNAL - Flame is proved while gas valve is de-energized. Inducer will run until fault is cleared. Check for: - Leaky gas valve - Stuck-open gas valve 23 PRESSURE SWITCH DID NOT OPEN Check for: - Obstructed pressure tubing. - Pressure switch stuck closed. 24 SECONDARY VOLTAGE FUSE IS OPEN Check for: - Short circuit in secondary voltage (24VAC) wiring. 31 PRESSURE SWITCH DID NOT CLOSE OR REOPENED - If open longer than five minutes, inducer shuts off for 15 minutes before retry. Check for: - Excessive wind - Proper vent sizing - Defective inducer motor - Low inducer voltage (115VAC) - Defective pressure switch - Inadequate combustion air supply - Restricted vent - Disconnected or obstructed pressure tubing - Low inlet gas pressure (if LGPS used) If it opens during blower on-delay period, blower will come on for the selected blower off-delay. 33 LIMIT CIRCUIT FAULT - Indicates a limit, or flame rollout is open. Blower will run for 4 minutes or until open switch remakes whichever is longer. If open longer than 3 minutes, code changes to lockout #13. If open less than 3 minutes status code #33 continues to flash until blower shuts off. Flame rollout switch requires manual reset. Check for: - Restricted vent - Proper vent sizing - Loose blower wheel - Excessive wind - Dirty filter or restricted duct system. - Defective blower motor or capacitor. - Defective switch or connections. - Inadequate combustion air supply (Flame Roll-out Switch open). 34 IGNITION PROVING FAILURE - Control will try three more times before lockout #14 occurs. If flame signal lost during blower on-delay period, blower will come on for the selected blower off-delay. Check for: - Control ground continuity - Flame sensor must not be grounded - Oxide buildup on flame sensor (clean with fine steel wool). - Proper flame sense microamps (.5 microamps D.C. min., 4.0 - 6.0 nominal). - Gas valve defective or gas valve turned off - Manual valve shut-off - Defective Hot Surface Ignitor - Low inlet gas pressure - Inadequate flame carryover or rough ignition - Green/Yellow wire MUST be connected to furnace sheet metal 45 CONTROL CIRCUITRY LOCKOUT Auto-reset after one hour lockout due to; - Gas valve relay stuck open - Flame sense circuit failure - Software check error Reset power to clear lockout. Replace control if status code repeats. If status code recall is needed, briefly remove then reconnect one main limit wire to display stored status code. On RED LED boards do not remove power or blower door before initiatingstatus code recall. After one status code recall is completed component test will occur.
It sounds like your lamp may need replacing. Before you go that route try all of these:
-Make sure the lamp cover on the bottom is fully attached.
-If you unplug the power cord while the fan is rotating, the lamp may not turn on about 1 minute when
you plug the power cord next time. After the status indicator stops blinking press the power button to turn it back on. May have to press it multiple times.
-If your Power Light continues to blink red/green then you should contact your dealer.
Sorry I couldn't be more helpful.
Red and Green bliking with no picture means a service problem. But you might try cleaning the filters first and being sure that nothing is blocking air flow through the projector. Red status solid means replace the lamp, but that doesn't seem to be the indication.
If it shuts off and then the power light starts blinking red or it never comes on but the power light just blinks red continuously that is usually indicative of the convergence ICs (STK 392-110). You never want to replace the ICs without also replacing the resistors that are associated with them. There are usually 6 resistors, one for each of the colors and there corresponding direction, IE Red horizontal, red vertical, blue horizontal, ect. In the case of this model tv all of the resistors are 2.2 Ohm and 2watts. You will find them right where the STK 392-110 ICs are. Right in front of them. They are blue and have this color code on them. Red, red, gold, gold. These are represented by stripes on the resistors. You can get the parts from www.bdent.com They carry the ICs and the resistors. If you do not feel comfortable completing this repair I could do it for you if you send me the board. My email address is: [email protected] The cost is 375.00 and that includes parts. Good Luck.
Both power light and status light a solid red with no response to any buttons indicates the bulb timer has expired. You need to reset the timer by pressing and holding the left arrow key, the right arrow key and the power button all at the same time for a few seconds.
If there are no problems, the projector will fire up, but you must replace the bulb as it will fail soon and perhaps explode when it does.
cutta, you will most often hear a click on boot then the fans start up and lamp will then fire. The picture will start to show up....at what point does it shut off? and do you hear a click when the tv is turning off? Is it the complete tv shutting down, fans and everything that turns off? Do you see any lights on the the front panel "POWER", "STATUS" or "LAMP", what are they doing?
If you see a Power, Status or Lamp light after it shuts off the below are what they mean if there is an issue.
POWER - STATUS - LAMP - CONDITION/ISSUE:
Off - Yellow - Off - Temp. high/dirty filter/excess room temp
Off - Off - Yellow - 4000 hrs. Lamp usage warning
Off - Off - Blink Yellow - Lamp Cover open
Off - Blink Yellow - Off - Air Filter Cover open
Off - Off - Red - Lamp failure (failed to turn On or broken)
Off - Blink Red - Off - Fan Has Stopped
Off - Red - Off - Circuit failure (short) or DVI cable disconnected
If you want to check for the last "Error Code", after you first turn the TV on, by pressing the front panel ?DEVICE? and ?MENU? buttons at the same time and holding them for 5 seconds, it activates the Error Code Mode.
The ?Power LED Light? blinks/flashes (1/2 sec delay) and then flashes again denoting a two digit Error Code indicating no problem or an error has occured since the last Initalization. i.e. "Power light" blinks 3 times (1/2 second delay) and then blinks 4 times then 1 sec delay and repeats a few times. This would mean "Error 34 - Lamp abnormality". See below for error codes.....
Error Code - Description or issue
12 - No Error detected, check Power Supply
32 - Lamp Cover is open
33 - Air Filter Cover is open
34 - Lamp abnormality
36 - Light Engine (DMD or LAMP Fan stopped)
37 - Exhaust or Lamp Ballast Fan stopped
38 - Lamp temperature high
39 - DMD temperature high
41 - Short is detected
44 - DVI cable between FMT & Engine disconnected.
Sorry for the long answer but it was an open ended question.
