Most of these sets (I have seen about 12 with this problem) have a problem on the Power Supply board inside the set.

With set unplugged and back cover removed follow power cord to the power supply---it should be a fairly large board as you look from back on the far right side---facing the back of the set.

What happens mostly with these sets is they were among the first to switch from regular leaded solder to LEAD FREE solder and over time they develop bad connections on the bottom of the board

Every one of them I have seen, with the board removed from set and completely soldered by hand----came back to life and had no issues.

I have the entire service manual for the 610HD which is similar to your set.


If this told you something you did not know and you want more help, rate this solution as very helpful as I do this here for free.

Hisense 50k22dg should i replace led strips first or power board


I would inspect the power board for mushroomed caps and brunt traces. A edge lit led screen has two ribbon cables coming from the power supply, I would unplug one at a time to see if one side lights up. Both led strips rarely go bad at the small time. The problem is most likely in the power supply.

LED TV screen has flickered momentarily and faded to black. I have sound and power buttons light up. LED solid black, not lit. Bad LED Driver board?


Sounds like Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. 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 inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I have a LG 50LN5600 LED Smart TV w/sound no/pic Have replaced the power supply board and t-con board. Main board only one left and research says that this would not be a main board prob. Any help?


If the LCD panel back light is not lit you have a bad LCD panel. If the back light stays lit when the set is turned on then you almost certainly have a bad main board since you have already replaced the power supply and T-con.

If you take the back off you might find a couple of bulged electrolytic caps on the power supply board that need change, or just buy a new power supply at www.partstore.com

Replaced drum on Dell 1720dn printer. Where is


This should fix the drum light being on that 1720

Turn off the power using the switch on the back of the printer. Open the front door of the printer. Hold Continue button down, power on the printer, and continue to holding Continue down until the LEDs begin to flash. When the LEDs start to flash, release Continue button. The LEDs will continue flashing until only Error LED will be lit. Close the front door. Continue, Ready/Data, Toner Low and Load Paper LEDs should be lit. Wait till the printer completes the POST process. POST is complete when fan noise and rollers stops. After POST wait for 5 seconds Press Cancel button 4 times slowly until the Toner Low LED is lit. This is the procedure resetting the counter. Press and hold Continue until all LEDs begin to cycle in sequence, then release Continue. Now only the Toner Low LED will be lit. Cycle the power of the printer: Remove the power cable - Wait for 5 seconds - Plug the power cable back to the printer - Power the Printer on.
