Best approach is to replace them ALL. what hasn't failed yet will do so in the future and come back to bite you. you can change out all the caps in an afternoon if you don't get interrupted.

My 98 jimmy is not starting up . Engine turns but will not start


Pretty sure I know what is causing this. common issue in GM's. Your security system failed .this has happened to me before I found a module that can bypass it and your car will run again and its very inexpensive and you can do it yourself. check it out see if you think its it. your car make and model are on the list for this issue.

The set has the 3 strikes and you are out rule built into it.

Set will attempt 3 times to come on and if fails enter shutdown mode.

A short or an issue almost anywhere in power supply or high voltage circuit will cause this.

The only common cause is the set may have developed bad or cracked solder connections where the high voltage transformer solders in.

This happens because of poor soldering and expansion and contraction of the board happens when set gets hot and then cools off.

see attached photo of a high voltage transformer also called a Flyback Transformer.

I need the user manual for panasonic ag-ds555


I can't find one online either but the AG-DS850 manual should be extremely close if not the same (I can't see any differences in the front/rear controls except the model#): You can download the 850 manual here: ftp://ftp.panasonic.com/provideo/om/agds850_en_om.pdf

Defective monitor samsung 740n no display how to fix it?


Common failures are due to bad DC filter caps, look for caps with domed tops first.
If you are going to DIY and already try the monitor with another PC, and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/
Post back what you see inside so we can guide you further and it will help out other people in the future also.

What causes E74 on xbox and what can be done to fix this issue?


hi there,
E 74 is basically caused from the xbox overheating. This is a common problem with the older xbox's. What happen is that heat builds up inside the console due to poor heatsinks and poor air circulation inside the xbox, thus causing the video/graphics chip thermal glue/paste to become unseated and causes your xbox to stop working giving you the error code. There are a number of ways to fix this, 1 would be to send back to microsoft if you dont know anything about the console and do not wish to fix your self. 2 the cheaper way :) is if you are handy with technology you can do this yourself and save some money in doing so. The best way to show you is by video guides, rather than writing it down here and trying to follow the steps. There are loads of video guides out there (youtube,360 sites/forums etc..) Just google E74 fix xbox360 and you will find plenty of guides,tips,solutions. Hope this helps

Very poor quqlity image and the image doubles


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

Hi there,pleace i need help.i have a panasonic dvc20,and during recording the message always appears : press the reset button.when i rest the camera,after some seconds of recording the same message appears...


the dvc20 performs a self-test routine which includes testing the operation of the mechanical deck. if one or more tests fail, the "press reset" comes up. most common problem is a poor connection to one or more motors in the deck; oxidation or dirty connectors causes this.
