My Vulcan VC4GD will run and come up to temperature but fails to maintain temp. The red fail light is on and the ignition board led is flashing 3 times for ignition lockout.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Hi,

if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.

• A flashing lamp light means the lamp failed to ignite. It could be a lamp driver problem or lamp failure. Replace the lamp to resolve the issue. If the issue is not resolved, then service the projector.
• A flashing Temperature light signals a fan error. Turn the projector off and allow it to cool down. If the light is still flashing after the projector is turned back on, service the projector.

Goodluck..

It is helpful to have the sequence of the blinking red light. This may help:

3. Error Code Operational Check

Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Operational

Check. When the TV is switched Off, the code automatically resets to "12" No Error.



Pressing the front panel "DEVICE" and "MENU" buttons at the same time, and holding for 5 seconds,

activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem

has occured since the last Initalization.



Note: The front panel buttons must be used, NOT those on the Remote Control.



• 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 LSD (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.



4. Error Codes

The Error Code designations indicating malfunction, or no malfunction, are listed below:

POWER

Off Off Red Stby Lamp did not turn On

Off Blinks

Red Off Low

Abnormal LED Indications

Error Codes "DEVICE" & "MENU"



Error Codes Description



12 No error detected

22 Recovery from Reset

32 Lamp cover is Open

34 Lamp abnormality

35 DM Fan failed (Chassis Fan)

36 Exhaust or Lamp Ballast Fan failed

37 DMD Engine Fan failed

38 Lamp temperature abnormally high. Remove Lamp to check filter.

39 DMD temperature abnormally high

41 Short is detected (Standby Power Supplies)

42 Lamp Fan failed

44 DVI cable between Format and Engine disconnected

46 DMD Temp. Sensor not detected (check DT connector))

47 DM Temperature too high

48 Engine power supply short detected

51 Speaker Drive circuit short detected

52 HDD excess temperature (V30+ & V31 only)

55 HDD Fan Stopped (V30+ & V31 onlyt)

check transformer....... then spark module cable for spark. if none, need spark module

Chances are it is the igniter go to Searspartsdirect.com

Error Codes
A green LED indicates system faults
Steady On: System OK
Steady OFF: Board control fault or no power applied
1 Flash: Ignition failure (control in one-hour lockout)
2 Flashes: Pressure switch fault, fails open (switch is
stuck open)
3 Flashes: Limit switch open (main or auxiliary)
4 Flashes: Pressure switch fault, fails closed (switch is
stuck closed)
A yellow LED indicates flame status
Steady on: Normal flame is sensed
Flashes: As flame weakens, frequency of LED flashes
increases
hope this is helpful.

Power LED flashes orange 1 x 5 secs. = 1 of 3 fans stopped. TEMP LED flashes 1 x 5 secs, = Temperature error. Lamp LED flashes 1 x 5 secs. = lamp ballast error. (check lamp 1st.)
Hope this helps.

HI, this is a failed power supply board. simply replacing the failed power board will fix this issue.

STBY LED flashes

2 times pcb X SUS TEMP (DD CON

3 times pcb Y SUS TEMP (I/O Block)

4 times Center TEMP

5 times Digital 5 volts

6 times PANEL FAIL (PDP)


try unplugging it for a while, from other forums looks like they sent them back to sony for repair
