I have a Sony Bravia LCD tv an it won't turn on at all the standby light is not even there I've tried turning on an off and leaving unplugged for an hour still nothing.? Help,


You either have a problem with your power supply board or main board. I would start with having the power supply fuse checked as well as the power supply board!

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.5_14_2012_1_18_09_pm.jpg

Please check on the main fuse box for the fuse to the turn signal as this can be the fault. If not check the voltage on the flasher unit to confirm if the unit is faulty.

I have a 2004 Silverado 1500. The rear lights won't turn off, pulled all the fuses associated with lights and they still don't turn off. In addition my right turn signal doesn't flash, both the...


Not sure, but I've heard a bad hazard switch can cause strange problems.
Also, if your truck has a body control module that controls interior and lights, that may be your problem, too. Good luck.

It is a fuser error.

Try resetting. To reset a Rank A error follow these steps:

1. Turn OFF the Main Power Switch.
2. Turn Main Power Switch ON while pressing the Utility/Counter key.
3. Touch [Trouble Reset].
4. Check to make sure that [OK] is displayed and the it has been reset.
5. After turning off the Main Power Switch, turn it on again more than 10 seconds after and check if the machine starts correctly.
If the error recurrs then do the following:
1 Check the Fusing Unit for correct installation (whether it is secured in position).
2 Check the Fusing Unit, PWB-M and PU1 for proper connection and correct or change as necessary.
3 Change Fusing Unit
4 Change PWB-M
5 Change PU1
