I would check to see if any capacitors are bulged or failing and replace them.

It definitely does not seem to be a problem with the Picture Tube. More like a cold solder. It is definitley not a job for a layman. Also, get a good technician to have a look, as locating cold solders is a labourous and time consuming process. It could also be possible that the main DC filter capacitor is getting dry, and may require replacement.

SOURCE: TV turns on & off

Hi there!
Exterior equipment attached to a standard tv cannot cause the set to switch on/off by itself.
I think you may have a power supply fault or else loose solder connections on the board, hence the "warming up" intro before the fault shows itself.
My suggestion would be a service technician if you are not familiar with electronics or TV's. Regards, JUS004

Norcent PT4233 no picture, black screen, but has sound. How to repair

The display (PDP - Plasma Display Panel) at the heart of this unit is a LG 42V7 model. There is a known bad solder "defect" on the YSUS board that causes this board to fall unexpectedly.

The bad news is that you have to replace all the primary boards on the display - ZSUS, YSUS and CTRL boards, as the failure can/often takes them all out.

The good news is that LG makes a repair kit for this panel. Its part number is 687VSNB03E and it contains the three boards LG6871QYH036D (Y SUSTAIN), LG6871QZH041B (Z SUSTAIN) and LG6871QCH053G (CTRL).

Hope this helps

Sylvania 6842THG won't turn on. the tv red light displays when you push the power button you hear a click and then 5 - 10 seconds it goes back off


I have been having the same issue. I unplug the TV for 10 minutes and it usually works fine. I moves all of my A/V plugs to a single power strip and that helped a lot. Since then, the TV went into protection mode only once in 2 weeks. Next, I will use a power strip that includes the cable protection.

Remote quit working.....tv comes on and goes off by itself at various times


Sometimes Buttons on remote control "stick" underneath the faceplate. It's possible the on/off button is jammed. A lot of times when a button is jammed the other buttons fail to work.

Could also be the reason you needed to replace the batteries with a button being continously pushed will drain the battery life.

Push every button on the remote and kinda wiggle each button while pushing to possibly see if its stuck.

Hope this helps.

No display/picture. Sound and power work perfectly.


Based on your problem listing I believe you have an LCD tv.
You can check your tv by turning it on to a station that normally
shows a good picture. Shine a bright flashlight and place it against the screen. Look around the edge of the flashlight for an image moving around. If you see it, your problem is with the inverter/CCFL..

LCD TV Remote quit working


Hi,
First thing, turn off the TV and unplug it for about 2-3 minutes. Remove also the batteries on your remote. Re-install the batteries on the remote and plug in your TV. Power on your TV using the remote. No luck?
Norcent may not be supported by a universal remote. If you just bought your unit new (maybe Best Buy who carries this brand) you are still covered by its warranty. Below are ways you can reach Norcent.

Fujitsu 42" Plasma Display shuts off after 20 minutes


This is most likely caused by the Main Power pcb.

See Fujitsu Service Bulletin on this problem in a similar model from Fujitsu. -see link below
http://tomtom2k5.free.fr/fujitsu/PDP-0035-06.pdf

A competent service technician should be able to implement the service bulletin.
A similar service bulletin is probably available for your model. Request bulletin from Fujitsu 'service@fujitsugeneral.com'
