Ur high voltage is dying,it the FBT,the flyback transformer is cold solder or dying.The big black block of plastic with a red wire with a cap that hook to the CRT(tv tube).That the cause.

Toshiba will not boot


It needs those things to start up. If you reinstalled them in the machine and it won't start up you need to check some things:
Does the screen flicker when you power it on or does it stay completely black? If it stays completely black, then the connection from the screen to the computer itself is lost. Normally it is caused by a broken cable.

If the screen flickers and then goes black, then check the following:
Does it beep at you? If it does, then the amount of beeps is important. It will state in the users manual what that numbers mean.
If it doesn't beep, then my best guess would be that there is something wrong with the power distribution in the machine.

The controller board for the screen is going bad. check shopjimmy.com for replacement parts. It's not a difficult job to do. Once the back of the TV is removed, you'll see it near the center of the screen.

Black Screen


If audio is present, the picture should also be there. If not, check the video output section circuit for fault. Check all the solder terminals for any loose soldering to this board. Audio output board can be located at the neck of the picture tube, will directly plugged on to its back. Re-solder all the suspected solder terminals; by applying a little more solder.

I have a 32" RCA LCD tv , rlc3210 power input says


Is it hooked up with HDMI cable?

If so try unplugging the HDMI cable and re plugging the cable in, sometimes those cables work loose and if they are not tight, it will cause your screen to flicker. Happens to my TV once in awhile.

Samsung 226bw visible flickers just after it is turned on


You may have a faulty inverter or loose power inverter connection. OR
You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
