Red light lit on front panel indicating a bad lamp

The red light is lit on the front panel.I replaced the lamp but the red light is still lit.
I suspect a power supply( capacitor) problem. where is the location of the power supply board?

Thank You
Neal

    I figured that the power supply board would be close to where the power cord is.
    I have the back off the set but how do I get at the power supply board?
    It cant be too difficult. According to the posts others have done it.
    Techman may know the answer to this.
    THanks

    I need to know how to get at the power supply.

    I have the back panel and the rear plate off.

    I can see where the power cord goes but how do I disassemble whats in front of it?

    According to the posts others have done this but they dont say how they got at the power board.

    If I can get the power supply board out I can check the caps.

    Techman has the answer,he answered most of the similiar posts.

    Thanks

    I know I should check the power supply and I know where it is, I just dont know what to take apart to get at it.
    Im assuming here that the lamp is bad so I would like to check the power supply and dm boards before I invest in a lamp which may not work.
    I have the service manual but it does not show what to take apart to get at the boards.
    Thanks

    If I can get at the supply I can check the caps.

First check F9A06 this blows at times. If not the problem you anc do This model is equipped with a keyboard lock feature, this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds

It'll likely be right behind where the power cord from the TV comes from.

I changed the lamp on my pt44-lcx65 panasonic tv and everything comes on great but red lamp light is still lit


Turn on the television.
  1. Press the volume down button on the TV display (not the remote!)
  2. While pressing the volume button, press the "split" or "PIP" button on your remote.
If it works, you'll see a message like this, an the lamp indicator light will turn off. Success!

I have two monitors. One Samsung SyncMaster 2233 an one Samsung SyncMaster 2243. My problem is that the SyncMaster 2233 for some reason is totally black. I'm usually not terrible with these things, but my...


hello Gabriel

Could you check your SyncMaster 2233 for me and tell me your findings. If this monitor is connected from your computer and when both switch on, did the led indication lamp from your monitor lit steady green? or this lead indication lamp lit green then turns red?

1. If the led indication lamp lit steady green then there is nothing wrong with the settings, configurations, driver or hardware on your computer. The problem would be the backlight inverter lamp in your monitor is busted. Or it could be the inverter board that supplies high voltage for the backlight inverter lamp that is bad. You can replace the backlight inverter lamp located at the upper and lower part of the monitor with a replacement part you can purchase at shoppejimmy.com. Inverter board repair can be risky if you don't have the skill. Even opening the back cover of your monitor and replace by yourself the inverter lamp is risky too, could inflict more damage. you can bring it to a local professional service man.

2. If the led indication lamp lit green then turns red, then if not the video card the power supply section from your monitor is bad, you can replace polarized capacitor with same value. Just inspect and those with blown or leaking capacitor. You can also check the terminals and solder joints for the 15-pin vga terminal connector where vga cable is connected on your monitor. Resolder the terminals.

3. If the red indication lamp did not lit at all. Power supply section in the monitor is bad. You can check the output voltage from the power supply section. +5VDC is supplied for the main board and +24VDC is for the inverter board. Replace leaking or blown capacitor with same value.

Just remember, this should be done when computer and monitor is turn off
Post back if you have more questions. I am willing to give you assistance.

How can i tell if the lamp is bad. The t.v tries to come on but it never comes on. A red light flashes next to the bulb sign on the front panel


The indicator light next to "lamp" flashes when the projection lamp needs to be replaced, take a quick look at your operators manuals "troubleshooting" section for help on what these "warning lights" on the TV mean.
Good Luck !

It is an indication that the projector is in sleep mode. Press power button and check for any changes on the led indicators. If the power turns red, it means unit is hot. check if the fan is working and if the air filter is clean or needs cleaning. If the lamp turns red it means the lamp is busted, You will experience this since lamp is clearly blown. But if both lights are red, it means that the unit is busted and will require service.

If you just replaced the lamp then there's something wrong in the power circuit or you have a bad lamp. If you can I would take the back cover off and look at the board where the power cord connects and lok around it for swollen capacitors. Let me know if you find anything.

Tv went off while watching a program power standby red light blinks 6 times then pauses then repeats tried unplugging unit waiting a few minutes then replugged same results nothing. can anyone help me ?...


Here's an excerpt from the Sony Manual online. And the link - http://esupport.sony.com/US/perl/webtree.pl?template=EN&mdl=KDF55XS955&content_id=68&category_id=11&problem_id=52

The POWER/STANDBY (red) indicator flashes three times
If your power/standby indicator is flashing in a pattern of three flashes, this may indicates that the lamp cover is not attached securely. Follow the directions in the Operating Manual under changing your lamp that related to closing and securing the Lamp Cover. Ensure that the Lamp Cover Door is securely fastened by tightening each screw.

The POWER/STANDBY (red) indicator flashes continously
If your power/standby indicator is flashing continuously, and the lamp cover has been secured, your TV may be in need of service.

The POWER/STANDBY indicator is lit up green (not flashing)
A sustained green light indicates your TV is on.

The POWER/STANDBY indicator is lit up red (not flashing)
A sustained red light from your power/standby indicator simply indicates that your TV is in standby mode. This shows you that your TV is ready to be turned on with the remote.

Is it the power light and not the lamp light? If the lamp light is flashing then replace the lamp.
