Replace power supply for mitsubishi LT-52148


see this instruction. God bless you

    • 1
      Unplug the monitor power cable. You should never attempt to disassemble an electronic component without first detaching it from its direct power source.

    • 2
      Remove the screws from the back of the monitor and along the edge of the screen. Depending on manufacturer and model, LCD monitors will have screws located on different parts of the monitor's body. Once the screws are off, use a flat-tipped tool, such as a knife or a screwdriver, to pry the monitor open by dislodging the two halves; be careful not to tear wires connecting the two halves.

      Locate the power supply unit and take its metal casing off. Once again, different models of LCD monitors will have the unit placed in different locations. With the casing undone, unplug cables running from the power supply to other internal components. Mark the cables that you unplug from the power supply--you will have to plug them back in to the new unit.

    • 4
      Dislodge the power supply from its dock. In some monitors you might have to undo screws that hold the power supply unit in place. Remember the orientation of the unit as it was placed, because you will have to insert the new unit in exactly the same way.

    • 5
      Insert the new power supply into the dock and screw it in place. If you do not have a new power supply, read the label on the existing one to order a new one from the manufacturer or from a third-party supplier. Obtain a power supply unit that is compatible with your LCD monitor; never try to use a generic spare. After installing the new unit, plug in the cables exactly as they were in the old unit.

    • 6
      Put the power supply casing back on and reassemble the LCD monitor frame. Gently clasp the two halves of the monitor shut, making sure you have reattached all cables that you unplugged to take the monitor apart. Close the casing, tucking away all cables neatly so they do not get in the way of the monitor casing.

    • 7
      Put all the screws back on. Once done, you should have no leftover pieces (screws or cables).

Toshiba LCD TV 19Av505DG how to unlock the side menu


Hello
To unlock the TV do the following:

Disconnect the AC power for at least one minute to reset the clock.
Adjust the volume to the minimum using the Volume down button on the front of the unit.
Press and hold the Volume down button on the front of the unit and the 0 button on the remote control at the same time, holding them down for at least 10 seconds.
The user menu will appear with the V-Chip cursor blinking.
Press the ENTER key on the remote control and the NEW PASSWORD menu will appear.
Enter your new password.

The V-Chip is bypassed by holding the zero key on the original remote hand unit, and at the sane time holding down the volume down on the front of the TV set. This should reset the oide so you can enter a new one.
OK.

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.

TV needs servicing CERTIFIED TV EXPERT HERE, follow this information I provided 3 long solutions to this issue/s Solution 1 Before we start taking things apart, lets try your simple remove power plug routine and power system back up. Also, please try your unit on a few different channels to see if your problem continues on each channel. Your Main Board, Power Board, T-Control Board are suspected problems at this time. Press and hold the power button for about 15 seconds, the unit should power down by itself after you have powered it on. If it does not, then do not be concerned. Let me know if the problem continues. The first link below will bring you directly to the troubleshooting guide if you need to continue forward with the same error. Additional information http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide Failed TV and Monitors: http://s807.photobucket.com/home/budm/allalbums http://en.wikipedia.org/wiki/Capacitor_plague Parts: www.shopjimmy.com 2 Lets focus on the external portion of the TV set first (95 percent of all TV problems are related to things EXTERNAL To the tv itself) Check the physical CONNECTION of all cables by removing each wire bare or RCA and reinstalling it (Each power cable as well), once you have removed one cable, check it for fraying, and if it is already bare, splice a new fresh connection for it. 5. Check to make sure there are NO OTHER uneeded radios, system nearby. these systems, when powered on, will cause electromagnetic interference and prevent more than just severe tv interference SURGE PROTECTOR Surge protectors account for more than 75 percent of electric faults to stereo equipment. Lets start with your AC Wall outlet. It is standard in america that 220 Volts from out of these outlets. This implies that each device will be using 220 Volts (From within that grid zone). If anything including an alarm clock is plugged into any AC outlet socket in the vicinity of the stereo equipment/TV, it will cause electric outage, and prevent electronics from even turning on! Your TV needs dedicated electric power. If your TV is located in the living room then unplug everything else in the living room. Lets plug the TV set into a Dedicated socket. Check all light switches to ensure that power is on for that outlet. Check the TV cable for Fraying both on the ac wall end and where it plugs into the TV. Check all GFCI outlets to ensure that all red reset buttons are pushed in, check the circuit breakers for proper connection and they are turned on. Now, lets try the TV set without it connected to any cable services, vcr, dvd, stereo system, etc. Please respond if we have found a solution. 3 When troubleshooting these units, there are always several variables to consider. First check to see what last occurred with the unit such as did the children play video games, did the electricity go out due to bad weather. You may see that there are many possibilities but let's focus on what occurred last to the unit. Once we determine what happened last, we may isolate the actual cause of the problem. The actual cause may be associated with projection issues, older versions (Picture tube), interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common with the error you have provided today. Please continue to look for anything EXTERNAL to the unit before looking at the internal components. I have been working on these a long time so feel free to follow up with me

Tv LCD RCA model L32WD22 what ic replacement can I use?


servicios,
Close the the unit up as you had before opening. Take the unit to a service centre and have them fix it. They don't have manuals to repair so, when they say, "We can't fix this" you take the work order and call1877-297-8391 and they will get you a new tv

Will not play on new RCA LCD TV tried different


Try hooking up your sony handycam to a different monitor or tv to make sure it is putting out a good video signal using an S-Video cable. Then once you know your cords are good and you have a good video signal, hook it back up to the RCA LCD unit. If it is still not working make sure that the RCA LCD is set to receive the Hi8 signal via the S-Video cable. There may be a switch or menu setting on your RCA LCD to accept the Hi8 signal or also refered to as S- Video.

I hoped that helped and good luck!

Looking for SK-26H520S Power Supply Unit


I had a similar problem where the TV would turn on then shutoff when bumped or over time. The clue was a "tick" sound when it shutoff. Unplugging and reconnecting the power cord go it going again for a few minutes anyway.

I took the unit apart and found the solder connection on the power supply unit was cracked where the main transformer attaches. The solder connection joins the PC board. I suspect the weight causes the joint to stress crack. This is easy to fix by removing the power supply and touching up the solder connections around the transformer. I'd check this first as it is very difficult to locate power supplies and other parts.

LNR-328W


90% of the time this is caused by a bad LCD panel. The other 10% is caused by a bad Main board. You may want to try and change the main board first. This set carries 2 different type of main board. You MUST look at your Version Number located on the side of the unit. (Version AM02 uses BN94-00667S.Cost $177.81) (Version 0001 uses BN94-00629R.Cost $176.14) LCD pane BN07-00194A Cost $806.49

WON'T POWER UP


I had the LCD repaired. It turns out that the power supply went out. It cost me a few hundred bucks but it was worth the repair rather than buying a new one for 3x as much.
