There are no LCD or Plasma tvs schematics out there,the tv corporations don't release them.U want to troubleshoot the power supply board must do it with ur own skills.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Power flashing on/off when plugged in


general info first and then some photos---

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

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signs of 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 the problem.
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 generic ones like Radio Shack). Many fuses are special even aside from amperage--Don't put 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 a standby power supply that runs 7/24 and a main supply (some are combined and some not.

Here aside from checking fuses you want to examine all the filter caps on the power/standby to see if any are puffed up or buldged up in some fashion--I attach a photo of a good one---top should be silver metal and PERFECTLY flat and 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 runs 7/24 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 buy and 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 this photo.

The standby runs 7/24 and to save money they use caps close to the actual voltage---not too smart but saves money when making and the get hot and dry out inside---hence the puff which is really nice as if have that 95% of the time if replace the caps (slightly higher working voltage please) you have a working set.

ls this part itself a filter cap or a fuse? If a cap it will have value, voltage rating and plus/minus marked right on it.

Dead set or what?

A big hum of 100 c/s in the output,i need the schematic for repair


You must be on 50Hz power. You don't really need a schematic to repair the unit. Since the hum is twice power line frequency, the likely cause is the electrolytic filter cap for the high voltage has failed. The cap should be obvious in the unit. It will be near rectifier diodes and have a voltage rating above 50 volts. To test, bridge the one in there with another cap observing the correct polarity. If hum changes, replace the original cap.

I do not know the exact value but if you trace out the copper trace from the rectifier output, it should go to the first filter cap and then there will be an inductor and filter cap after that, you can figure out the voltage rating from there. You can get the parts here: http://www.shopjimmy.com/catalogsearch/result/?q=ViewSonic+N3260W

OK changing the caps only resulted in proper filtering and voltage smoothing and did very little to solve your problem. Now what swollen caps are a sign of is an over voltage condition. what I would suggest because you may have a bad voltage regulator, is that you have to get a schematic and measure the voltage levels on the power supply to determine if they are correct or not. This will tell you if the regulator is bad or not. You do have a power supply problem you just have to determine where in the power supply. This can be done with the schematic and a voltmeter.
