SOURCE: My samsung tv model UN29F4000, has sound but no picture, no menus come up. I'm not sure if it has a tconn board or not. What is the most common problem with a tv with these symptoms

The most of this TV problem is that the inverter transformer built on the main power supply is bad, to fix it, you may replace the transformer , or replace the power supply module.

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. http://electro-medical.blogspot.com/
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.

take it to a tv repair shop and get a quote but at that age ( lack of spares) I would be considering an update rather than wasting money if the repairs are expensive

"quadratic function" diophantus , a greek


Let x be Diophantus' age when he died.

His son died 4 years before Diophantus (so Diophantus was then x-4 years old). His son lived half as long as Diophantus so when he (son) died he was x/2.
Diophantus' son was born when Diophantus was (x-4)-x/2 years old. That was 5 years after his marriage so when Diophantus married he was (x-4)-x/2-5 years old. We also know that 1/6 of his life was spent in childhood, 1/12 in youth and 1/7 as bachelor so (x-4)-x/2-5=(1/6+1/12+1/7)x.
Now you solve last equation:
  • x-4-x/2-5=11/28x
  • x/2-11/28x=4+5
  • 3/28x=9
  • x=9*28/3=84 years

Diophantus was 84 years old when he died.

Our Samsung J1455AV door won't open, just over a year old. Have cleaned the filter, re-run a cycle, turned off at wall. Help!


Hi


Thanks for using FixYa. To start with if the door lock is stuck and wont unlock then you can pry it to open, and just don’t try too hard. The issue can be with the door latch that is stuck, to unlock it you can stick a flat screw driver behind the door latch and then lever it to open so that you don’t have to pry it to open. Once it’s done, please make sure to replace the door latch assembly to avoid any further issues. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee
