I assume you checked & tested the fuse? so you have power into the supply but not out.
"can" capacitors have a triangular wedge in the top of them. If the top is swollen and or has a smudge discoloration it has been over stressed or is worn out.
Some hand held testers have a diode check on them. So you can test the diode
The IC chip may be the problem and if it is in a chip plug your in luck you can re & re it easy . If not, that will be a tough job and beyond my know how

Vizio lcd tv will not turn on but the

This is a very common issue with this model TV. The problem is caused by the power supply controller chip. This is a small 3 pin chip on the video logic board. When this chip fails the TV video board never gets the signal to turn on and display a picture. Here is a picture of the video controller board from the TV with the power supply controller chip circled, and here is a link to order the IC chip. Open the back of the TV and look at the little chip, you should be able to see that it is burnt. Replacing the chip should bring the TV back to life.

5130 no service

hello all you need to do to fix a dropping signal like it shows a signal when freshly powering up the phone then after a few second the signal lost. In this problem you may replace the PA IC. Check first the supply voltage of that said IC before replacing it. For a total No network signal shown on the device, check all the supply voltages across on its corresponding RF chips. if all the voltage readings were all okay. reply both PA and the RF chip alternaterly.

Did you check if 24v supply is coming to the chip ( through a fusable 10 ohm resistor ) ?.Look for dry solder on the sync chip ( 24 pin or 40 pin IC ).

Your partial resonance power supply IC chip with IGBT switch is bad. On your model of TV it will cheaper to replace the whole power supply module

No power to box ic is blown in power psu where can i get replacement as the top has come of chip its the ic1 or 4 chip but cant read anything from chip as no top  need to get it repaired

We can probably look up the part numbers, but we'd need the make and model of the unit. Can you please update this with that info? Also, is the IC marked on the board IC1 or IC4? Hopefully you can also indicate which IC is smoked. When we look this up, we will provide other parts that need to be checked. It is unusual for an IC in the power supply to be the only failed part.

Please update this with the above info.
