Philips (37PFLG777K/12) LED TV do not turn and do not show the Standby LED. 3,3V Standby can not be meassure.


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

LCD Turns Off after colors go crazy (inverted colors)


If the 5V are 3.3V then either
1) You are not measuring it right
or
2) The problem is at the power board, not the SSB; swollen caps on the power should be seen with ***** eye if that's the case
or
3) The problem is on the SSB board where the 5V are used for bunch of things, including step-down conversion to 3.3V used by bunch of the main processing ICs and likely a step-up conversion needed by the video decoder. Any one of those could be overloading and causing the drop.

But everyone with pro skills with a 2 channel scope should already know all that, wouldn't they?

I'm looking for a USB connector for my Fuji DX-7.


Your camera is intended for serial connection.
You can get RS-232 to USB adapters, but I'm pretty sure that they wont work with your camera. DX-7 was originally equipped with 5V Smartmedia cards. Newer (!) type cards are 3,3V. You can get a card-reader for 3,3V cards but not for 5V cards.
You can tell the difference between 5V and 3,3V by the missing corner of the card. Seen from the "golden side" 3,3V cards are missing upper right corner, while 5V cards are missing upper left corner.
I don't remember if DX-7 could use both types.

Toshiba Satellite a-100 can`t power up


The RAM could be faulty.
Try and get the RAM tested in another laptop or at your friendly computer store.
Also can you hear the hard disk spinning.
Maybe it is booting up but you can't see anything on the screen, there might be a slight image on the screen, look at it at an acute angle.
Connect an external monitor to the laptop, power up the monitor and then the laptop, if you see a normal image the the problem is the backlight on the LCD screen.
Get back to me if this is the case.

2)Take the hardened steel needle or watchmakers screwdriver and clean (scrape) both contacts off any visible residue till they are shiny. aaaaaaaUce dust blower to get rid of scrape-offs.
3)Make sure the contacts are touching the corresponding battery side only and not shortcuting the battery.

Do not forget to rate please.
