SOURCE: I have a Panasonic TH-42PX80U TV. When I power up

Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps

SOURCE: i don't know which is right x-sus & y-sus or power supply 12/22 codes

If they are on left and right sides look from front of set--if not Google the model for a service manual which will have a pictorial showing which is which.

SOURCE: schematic diagram for power supplys LG 60PC1D-AA

I do not have the schematic, but have a testing / troubleshooting guide for the 60PC1D 1st and 2nd generation, which gives some good insight in organization and functionality of the power boards.

This is what we ourselves step on when repairing - LG often does not publish schematics for power boards and sustain boards.

contact us if interested

Acaer aspire 7736 z is not powering on


Remove main battery, and try to power up, no change, check power supply for correct voltage, if okay, the DC jack in the laptop is a common source of trouble from no power to intermittent operation. The computer will need to be torn down to address the problem.

Viewsonic n4251w power supply, no start


Power supply is first place to look:

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

Power turns on and off


Sounds like a thermal issue. New power supply might be overheating the cpu causing the thermal sensor in the cpu to automatically shut down so the cpu doesn't fry. You could try adding a case fan or two plus upgrading the spu heatsink/fan. Hope this helps.

Shot down of laptop


It can be two things. One is the adapter for the power cord in your computer has been damaged and may not fully operate or your power supply has a fault it in somewhere. Test the adapter in your laptop with another similar power supply and if it works you know its the current power supply you have, if not its the adapter and it needs to be replaced and sometimes that can mean a whole new motherboard depending on what brand and model laptop you use.

Hope This Helps
