There is usually an identical resistor somewhere else on the circuit board, so if you cannot read the colors of the burnt one, you can read the colors from an identical resistor on the same board. If you just replace the resistor, it will probably just burn out again or damage another component, you have to find the cause of the resistor burning out, most likely an electrolytic capacitor failing. Look for bloated or seeping capacitors and replace those as well. Also look for broken or burnt toroid coils.

Rad-5 LCD has no picture


Hello,

This usually means the power board is not putting out the correct voltages to run the monitor correctly. The power board can be repaired if you can solder parts. Check out the pictures on our web site at:
www.ccl-la.com/badcaps.htm Now open the back of your monitor and check for parts that look like the blown capacitors in the pictures on our site. Replace any that you see and you should be back running again. The values you need to purchase will be marked on the sides of the bad ones that come out of your board, it will be marked like 220uf, 470uf, 1000uf etc and a voltage value. Be sure to order a high quality part not like from Radio Shack, also use a high temp replacement 105c marking. If you don't want to do the repair yourself we do offer a repsir service for $35 plus return shipping. Let me know if you have any additional questions.

I hope this helps, if so please rate our solution.

Light bulb bad?????


You may have a faulty inverter or a faulty CCFL lamp.

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.

My solution:
Open the monitor. Take off the mainboard. There´s a supply board for the backlight under it.
Replace the two purple capacitors (150uF/25V). These are from a bad batch.

Also replace fuse F1 (lightbrown SMD-component) on the bottom of that board (near the long side).
It has blown as a result of the bad capacitors.

In my case the values were dropped to 25 uF. And the internal resistance (R) was more than 2 ohms.

That´s it. Hope it helped you.

LCD Monitor goes off after 2 sec.


Check all cracked solder joints and resoldered and check two smd transistors near the inversors good luck

Picture problem


You might want to try another smaller value of resisters I guess. Before you do that, check and adjust image setting using the screen buttons.
