How do I flip the picture after replacing the main board?

Go to service mode and there should be an option to flip the picture, not sure why this should happen when selecting reset as its more common when replacing the main board

Fault to the main power supply regulator section. 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. Surf the site with patience. Pull up older posts.

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.

Flip the TV over! Just kidding!! When you installed the main board was it identical to the old main board? If so, you might want to look at the old board and ensure there are no jumpers that needed to be set on the new board. Some companies make generic control boards for tvs but have different jumper settings for different models. The jumpers are just little black blocks that connect different pins to each other on top of the circuit board.

Configure Windows "video" properties to have Windows "rotate" the picture 180 degrees, i.e., make Windows produce "upside-down" output, and the screen will "flip" that output.

Hi,

there is nothing wrong with your screen, the problem is from the flex that connects your screen to the phone's main board. This flex must have worn out that's why your screen is not displaying any picture.

The problem is common with flip and slide phones. The flex gets worn out as a result of constant opening and close of the flip or slide phone.

I would urge you to replace the flex and I am assuring you that your screen will display picture again. You might also be lucky to find out that the flex is not well fix, that is, it may have loosed contact.

If you cannot change the flex yourself, maybe you should take the phone to a local repairer within your vicinity, so that the flex can be fixed/replaced.

Take care.

Good luck.

Either the flip assembly has a problem with the ribbon cable and needs a flip assembly replacement or the LCD screen is defective, replace the flip assembly if not its the main board, either case the phone has to be swapped or replaced ( flip assembly first if not then whole phone or main board.

Good luck and please rate and vote for me if I was of any help. Thanks.

A technician would need to replace the main board.

its pretty simple

1. remove 4 screws in the back of phone.
2. remove back cover
3. unclip lcd connector from main board
4. remove main board
5. reassemble with new flip
