I have a Westinghouse LCM 19v7 monitor that stays on for a few seconds and picture goes off. I know about the capasitor replacement but there is another conponent that I need to replace. It is the pow


Hello,

That is the correct value. That resistor just gets very hot and discolors the PC board around where it is soldered. You should be able to remove all of the old solder and scrape the resistor leg to get it bright, resolder the leg to the copper pad and you should be good to go.

Please show me value for resistance location no are 3133 and 3407


hi,
The resistor 3407 is 1ohm 2W resistor
I have searched in the circuit for 3133, but i didn't find it . can you tell me in which section you have seen that resistor.
if you send me your email id through fixya will sent you the schematic diagram.
ok

Hello bad minton 2 hi, check the common things first.
1. power cable, make sure its good. 2. AC mains outlet. 3. Loose AC port connection of the power cable. 4. Power switch.
If all is OK. problem is the main power supply board. Now you may need to open the back cover. Caution: this should be done by a pro. 1. Check the fuse for open. if open proceed if not go to 3. 2. Check now for shorts like diodes and transistors. 3. Check for voltage outputs. you need a manual or diagram for this. 4. To check for voltage readings, you need a multitester for this: 4a. check the ac 110/220 volts entering the power supply module. check the cable. 4b. check the dc output from the filter capacitor. no output, check the fuse or fusing resistor. diodes 4c. now the voltages at the VCC line after the regulator. If no readings problem with the switching circuit. Note this is not as simple as you think. have a tech guy do the work if you cant find the problem.

Black Screen One resistor is found Blown inside BWB but value unknown ! Please help !


Depending on the resistor, the values for a resistor is color coded, meaning that there are a couple of lines of colors and each color line represents a value. Do a google on Resistor coloring chart and you might find your answer. If the resistor is a surface mount one and very tiny, you might be out of luck as these are too small for the manufacturer to print the part number on. Only the manufacturer has that part number and can be very hard for you to contact them about.

I need to replace one of the fuses on the inverte board. What size do i purchase.


I use 2.5A PICO fuse, but before wasting new fuse due to short circuits you should solder in a 1/2w MOX resistor in place of the fuse and measure the voltage drop across the resistor so you can calculate the current draw by the circuits, if the resistor burns up right away, then you have shorted out output transistors in the transformer driving section. Also check the two large electrolytic caps also, if they are bad, it will cause the fuse to blow also due to high frequency oscillation.
