Samsung lcdtv la22a450c1 few days ago late start but now standby release lcd no start.replace new power supply


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.

Samsung plasma tv no picture no sound


Easiest thing to do is check out the power supply, a common source of problems. If it does not properly feed associated components they will not work properly if at all. Cross your fingers.

Samsung LCD TV 22inc Model No LA22A450C1, no picture ( white screen) only sound....


This type of failure is related to a defective Tcon board. I would suggest if you are DIY to check for proper connections from the main board to the Tcon board, if all the connections are good.. check for proper voltage from the power supply to the Tcon board. If all the previous checks are good, check for an open fuse on Tcon board.
Let me know if you require further assistance.

F01 error code


Completely disconnecting the electrical power and then reconnecting it will sometimes reset the board and it will operate properly. If your dryer continues to operate properly, then resetting the control board may have fixed your problem.
If the dryer motor continues to stop working, then you may have a bad control board. A wiring problem or drive motor failure could also prevent the dryer from continuing to run properly. A technician is normally needed to diagnose and repair this type of problem. If the F-01 returns and will not clear, then you will need to replace the control board in the dryer.

Model no.LA22A450C1 5.VOLTAGE absent


Going to be hard to trace since no schematics are usually available except to authorized service centers.

The 5 volts should come from the standby power supply which is usually part of the main power board.

If you feel lucky you may want to buy and swap the board out.

Also with set off check for a short to ground on that line.
