Question about Sharp Televison & Video

TV will not turn on. I have put in service mode and it shows a lamp error #4. I reset it to 0 but it still will not turn on. Now I can't even get it into service mode any more.

    Was looking for a more technical answer and perhaps something I could do myself rather than "perhaps you should contact your service provider". With the TV in standby mode (1 red light) you press power on the remote. The red light turns green and the normal sequence is that the second light then lights up green and you get a picture. Now, the red light turns green but before the second green light comes on the 1st green light turns back to red and starts blinking and then no picture. I know how to start it up in service mode. Power off, volume + channel- and power on. Then I usually go to lamp error which is an error code 5, set it to 0, power off, wait, power on and everything was fine. This time it was a lamp error code 4. Set it to 0 but that didn't seem to work. Now having trouble getting it to start in service mode at all. Let it rest for 30 mintes and it started all by itself but would like to know what is going wrong.

Hi, your TV is experiencing Lamp problem...

How Can I determine if my TV has a Lamp?

If your TV is a projection type TV such as DLP, LCD, HDILA, LCoS, SXRD it probably has a Lamp. CRT type PTVs and Flat Panel type TVs do NOT have Lamps or they are not replaceable. Most TVs that use a lamp have an LED (light) on the front panel labeled "Lamp".

Where is the Lamp located?

Do NOT open the lamp compartment unless you KNOW that the TV is unplugged from the AC power. Most Lamp compartment doors are located on the rear or side of the TV and they are somewhat obvious and usually labeled. Other TVs have the lamp compartment in the front behind a bezel that may be secured with thumb screws in the back. See your Owners Manual if you are unsure or better yet -Request a Free TV Repair Estimate.

What tools do I need to get the Lamp Assembly out?

Consult your Owners Manual. DO NOT attempt to remove the lamp if it is hot! Some TVs use thumb screws and require no tools, but most only need a common Philips and/or a medium flat tip screwdriver. Some TVs use a HEX wrench. If you are unsure or do not have the correct tools - Request a Free TV Repair Estimate.

How can I determine if the Lamp is Bad?

Do Not attempt to remove the Lamp if it is hot! Do NOT touch the face of the lamp. Look into the lamp and see if there is broken glass in it or if the glass tube is discolored at its base, if so then the Lamp is Bad. A lamp may look like new and even light for a while and still be BAD. There is NO reliable way to test a lamp that looks good. If your TV's Lamp Error indicator says the Lamp is bad, then it most probably is (BUT not always).

Can I replace the Lamp myself?

Most manufactures design their TVs so that you can replace the entire Lamp Assembly yourself and these instructions are included in your Owners Manual. Other manufacturers intend that the lamp be replaced by a technician only. And some models the Lamp must be replaced by a technician. BEST ADVICE - Purchase only the original Lamp Assembly listed in the Owners Manual if you plan to replace the Lamp yourself. Substitute replacement assemblies or Lamp only replacements (without the "cage") can prove unreliable at best and dangerous at worst. If you are not sure - Request a Free TV Repair Estimate.

I installed a new Lamp but I still have Lamp problems!

Did you use a factory original part? If not, this could be the problem.

Most TVs have a timer that must be reset when you replace the lamp. The instructions for this procedure are located in the Owners Manual or come shipped with the new lamp. Some manufacturers do not publish this information or may even require a special "service" remote control for some models to reset the lamp timer.

You may have a defective Lamp Ballast (electronic power supply for the Lamp) or other problem - Request a Free TV Repair Estimate.

I guess that will do..

Take care....

Error h4-00 code on AR- 5127. please what can i do to reset it. Thanks. It also says call for service even though the machine is new.


Hello,
this error occures if:
The setup temperature (about 90°C) is not reached within the specified time (about 17sec) from turning on the power.
When the temperature of main heater lamp thermistor falls below 140°C in the standby mode or printing.
When the temperature of main heater lamp thermistor falls below 50°C in the pre-heat mode.

AS POSSIBLE CAUSE:
Main heater lamp thermistor defect
Main heater lamp failure
Main thermostat failure
Control PWB failure

Check the heater lamp blinking with SIM 52.
When the lamp blinks normally:
Check the thermistor and the harness.
Check the MCU PWB thermistor input
circuit.
If lamp lights and stays lit:
Check for disconnection of the heater lamp
and thermostat.
Check the interlock switch.
Check the power circuit and the lamp
control circuit on MCU PWB.
Clear the display of self-diagnostics with
SIM 14.


To clear, enter sim mode:
1) #/P key (program) ON ? Asterisk (*) key ON ? CLEAR key ON ?
Asterisk (*) key ON ? Ready for input of a main code of simulation
2) Entering a main code with the 14-key ? START key ON
3) Entering a sub code with the 0-key ? START key ON
4) Select an item with the scroll key and the item key.
5) The machine enters the mode corresponding to the selected item.
Press START key to start the simulation operation.
To cancel the current simulation mode or to change the main code
and the sub code, press the CUSTOM SETTINGS key.
* Canceling the simulation mode to return to the normal mode
1) Press CLEAR ALL key

if clear with sim 14-0 doesn't helps, choose sim 52 to check the lamp, or call service!

I have a 42inch sharp aquos LCD tv and there is no power. The power button keeps blinking. There is no picture and sound. What is the fix to this problem.


Power problem are cause by many reasons, i.e Power supply circuit, Lamp driver circuit and most often the TV detects an error cause by power surges. To protect TV from further damage most LCD TV have protection circuit built internally. If this is the reason of your LCD TV not powering On, an error data must be reset back to zero.
To change data you will need to access the service mode and change the value of lamp error code to zero (0). Entering service mode requires a trained TV technician. Changing data can cause more problem to your television. If you are not qualified to service your television, please do not go to service menu codes. Moreover below are the process, pls do so at your own risk.
* Unplug the TV * Press and hold the {VOL -} + {CH+} buttons located on LCD TV unit (not in remote control) Note: If above didn't work, alternately use (VOL -) + (TV/AV input) buttons located on LCD TV unit (not in remote control) * While holding the above buttons, plug in the TV. * The TV will turn on with the "K" or "K123" appears om screen. * Use {CH+} {CH -} buttons to go and display the service menu. Note: If above didn't work, alternately use (VOL -) + (CH -) buttons. * Search for "LAMP ERROR menu" from the displayed service menu by using "up or Down cursor" from remote control, or alternatively use "CH - or CH+ to select "LAMP ERROR" * change it to zero (0) value, using {VOL+} or (VOL -) on remote control. * Turn the set off to exit the Service Menu.

C 0 e 0 0


the C000 code is a fuser error code on this machine. It can "sometimes" pop up after a power surge/spike/loss event, and needs to be reset in service technician mode. If it doesn't reset, but rather comes back, you probably need a sevice call for something defective in the fuser (lamp, fuse, thermister).

IF YOU'RE GAME, here it is...

To enter service simulation: press"Additional Functions" to enter "User mode". Press # key. Press </> to select a menu item. enter new data using number keys. Press "Set/OK" key. Press Stop/additional functions to exit.

Note: To reset E000, E001, E002, E003, go to service mode 4. select SET, go to "#7 PRINT-ER," in service mode. Then press Execute "#4 PRINTER RESET." Power the unit off/on.

Kyocera KM 3050 - error C3300


Error C3300 is a CCD Automatic Gain Control issue.

It could be poor contact in the connector terminals from the SHD PWB to the CCD PWB.

It is more likely a defective exposure lamp or inverter board that powers the lamp.

Try lifting up the Document feeder so you can see the optics frame through the platen glass and turning off and then on, the main power switch to see if the green exposure lamp illuminates.

A better, but more complicated way to check the lamp is to enter the service mode and run the exposure lamp test simulation. I will outline this procedure below. BE SURE NOT TO MESS WITH OTHER THINGS IN SERVICE MODE OR YOU COULD RENDER YOUR UNIT COMPLETELY UNUSABLE.

To Enter Service Mode:
Hit the "Status" button

Hit the following sequence on the numerical keypad:
1 0 8 7 1 0 8 7

You should be in service mode.

Use U601 by typing 6 0 1 and then "Start"

U601: Turning the exposure lamps on
Description: Turns the exposure lamp on.
Purpose: To check the exposure lamp.
Display:
CCD: Main Exposure Lamp
CID: Document Processor Exposure Lamp (inside the feeder)
Method
1. Press the start key.
2. Select the item.
3. Press the start key. The selected lamp lights.
4. To turn the exposure lamp off, press the stop key.
Completion
Press the stop key. The screen for selecting a maintenance item No. is displayed.

After checking the lamp(s) operation hit "reset" a few times to back out where you can type 0 0 1 "Start" to Exit Service Mode.

Comment by Soulvisitor, posted on Jan 03, 2008 Service mode info

Enter Service Mode: With the TV powered off (make sure it's off for a few minutes before trying this, or you'll wait for the customary cooldown period before anything happens if you turn the set off and try this stuff immediately), press and hold both the "VOLUME Down" button on the TV itself and the TV/VIDEO key on the remote control simultaneously for about 7 seconds (they say over 5 seconds in the manual). The TV will be turned on and it will have a screen full of status data atop an active TV channel.

Next, press the SWAP/STOP key on the remote for more than 5 seconds.

You should be taken to a screen that has " LAMP/FILTER/IIC" as a selectable entity. Press the Action key to select it and move to the next screen of info.

You'll see a status screen with the number of Service Mode Resets of the Lamp run time (I inadvertently reset my Lamp to 0 hrs after 95 hours of initial operation, and I'll show you how to avoid that in a minute). You'll also see Total Time, which I assume is total TV run time, Lamp Run Time, and Filter Time, all in hours.

You can backchain to the the prior screens with the Recall button on remote.

To exit this service mode entirely, you must turn off the TV.

You can also enter a different service mode menu to control a number of parameters, as I first learned from Doug McDonald at this link >>
http://www.avsforum.com/avs-vb/show...hlight=pt40lc12 when I was trying to learn how to perform service mode color adjustments.

Depress the "Volume Down" button on the set itself while concurrently depressing the "Recall" key on the remote for about seven seconds, and you'll be taken into "Work Mode". At this point, you can press the Action key, and select "Information", where you'll not only see Input mode (as usual) but also Lamp Run Time (but not Filter time or total run time).

You can enter the more advanced service mode menu by pressing and holding the Volume Down button down on the set itself while concurrently depressing the SWAP/STOP key on the remote for more than five seconds. -- This displayed a Factory Adjust menu, with bunch of settings. See Doug's message for more details. (Do not press Vol Down on the set and PIP/PLAY on remote simultaneously, or you'll reset the Lamp time to 0hrs as I did !)

Unfortunately, the service manual does not describe all the tweakable settings in the Factory Adjust menu.......

I did the following 'press and hold both the "VOLUME Down" button on the TV itself and the TV/VIDEO key on the remote control simultaneously for about 7 seconds (they say over 5 seconds in the manual)"

Will in the service screen I selected the number of hours of the lamp with the down arrows and the action buttons. Then I simply pressed and held the "down volume button" on the remote until the number of hours was 0. Then I turned the TV off, then back on and the message was gone. This worked for me.
