Repair oxidized board

On Samsung, a palm-swipe will save the image on the screen as an image file, which can be printed.
On iPhone, briefly pressing and holding the power button and then the menu button simultaneously, will do the same.

if powers on and has no video and no audio could be the main board, but first try this :

take a flashlight, turns on the tv and try to "see" the image while light up the flashlight against the screen , if you "see" something you have a bad back light inverter board.

below the posible parts number :

MAIN BOARD : Sharp 9JY0140CTJ05100
POWER SUPPLY/ BACK LIGHT : Sharp 9JY0940CTJ05000

TRY TO LOOK FOR AT :

or ebay

thanks

do you have sound? what color is the screen?

It will be almost impossible to repair a digital board. Will be better to replace it rather than trying to repair.

The phone needs to be reprogrammed / reflashed with the original software.

you need to obtain a rom image of the phones program and then place it on a storage card that fits to the phone.

Then you need to start the phone in boot loader mode to flash the program.

you can also try the recovery mode and see if allows you to fix the issue. more information about programming the phone here http://wiki.xda-developers.com/phpwiki213/index.php?pagename=HTC_Dream_overview_and_useful_information

if you require a rom file for the phone you may be able to find one from http://forum.xda-developers.com/wiki/index.php?title=HTC_Dream

if you are unable to get the phone to function contact your dealer or take it to a repairer.
recovery mode Hold Home button and press power button In this mode you can open shell/flash image/perform backup etc. depending on which recovery image you have on the phone. Press CALL+MENU+POWER buttons simultaneously to exit mode.
bootloader mode Hold Camera button and press power button In this mode you can install new system image (DREAIMG.NBH) from SD card by just pressing power button again.

Hello,

The flickering problem you have is caused by a failing power supply. There are parts called capacitors that are failing and causing the power supply board to put out pulsing voltages until it can stabilize. We have a repair guide posted on our web site at: http://www.ccl-la.com/blog/index.php/samsung-214t-repair/ If you can soldethen you should be able to do the repair yourself. If you don't want to do the repair we offer a repair service for this unit. You can get details for that service here: http://www.ccl-la.com/blog/index.php/service-request-form/

I hope this helps, If so please rate our solution.

That tester uses 2 (two) LR44 (1.5 volt) batteries.

See p.143.

If it's just this one button not working, or a group of buttons (depending on the model) it could be due to:

1. Door switch or temperature sensor problem preventing the oven from "starting" -acts like the button is bad but is being locked out by some other problem sensed by the control board.

2. Bad keypad
- We sometimes see a problem due to oxidation or corrosion on the keypad membrane connector. If you are comfortable working on such things, we posted a procedure that you can use to clean off the oxidation. Here's the link, check under the "Ovens" section:

3. Control board problem.
We repair these at www.fixyourboard.com

If you want to email us the full model number at [email protected] maybe we can help you pinpoint the problem.

You have a short in your button board in your camera or a bad button board. Send into Nikon to repair. You can also look on Ebay for the part if your technical skills are up to self repair.

I Can Assure You That This Problem Is Associated With 2 Capicators On The Power Supply Board.
