Technika LCD19id - No power to internal fuseMy LCD 19id-107 tv turned itself off and will not come back on. I have power to the 3 pin power connector at the rear of the tv. However i have no power to the internal fuse or main tv on/off switch. (It may be me but the fuse appears to be on the Neutral connection, following a continuity check. ??) Does the power go straight to the swith/fuse or through components first. Any help appreciated, as typically just out of warranty, Thanks Steve..

    I have the same problem. Technika LCD19ID-107 switched itself off, and will not turn back on.



    If you feed power in, nothing happens. But as you remove the power, the tiny red light on the front flickers, showing that power has been trying to get through.



    Anyone help?

Wont come on


I am assuming that you checked the power cable to the wall and the back of the TV. Most TVs have a three pin CEE22 type connector at the back for the power inlet. Sometimes this can work itself loose and come out a little disconnecting the power. Try wiggling it in until is home. You may have done that already, if that did not help it is more than likely the power supply or a fuse in the power supply is blown. Generally fuse is not accessible without taking the back cover off. Usually it is on the power supply board. Hope this helps.

Hi, My TV has been turning off by itself and


Good day!!!!

If your TV turn ON/OFF itself without sounds..The possible problems are voltage drop on power supply,overheat/overload,loose/cold solder of power supply or bad T-con board..

If you already inspected all capacitors on the power supply and all looks fine but it doesn't mean that your power supply board works fine because sometimes bad capacitors not look like bulged or looks fine visually but the value change its either lower/higher capacitance value.In that case you need to use capacitance meter to find bad caps..But before we do that,I have a procedure to minimize/eliminate troubleshooting.In this procedure you need a multimeter tester to perform voltage data check..

In this procedure we can determine where the fault came from..

This are the steps:
  1. Open the back cover.
  2. Look at the power supply board (it is usually connected directly to power cord).

3. Find the 3 long connectors near the aluminum heat sink.Those connectors having voltage marks on each pins so you can easily determine where did you get the voltage..

4. Point the black test probe to GND (ground) and the other probe (red) to 5vdc,12vdc/15vdc,24vdc..Let me know if you find any voltage drop or voltage lost..

5. If all voltages are works fine..The possible problem is on T-con/logic board or main board..But in that case the common problems is on T-con board I found it online $34..

Hope it helps..Just keep on touch to fix your TV and works fine again..

Sharp Model LC-37BD60U : There was a thunderstorm in the area. The Direct TV receiver is O.K. but the TV will not turn on. I have 120 VAC at the 2 pin plug where it plugs into the television. I have tried...


Hi,

Most likely the Internal Fuse has blown
You can buy replacement for very cheap
The Fuse will be located on the power supply board

You will need to remove the back panel of TV to get to the power supply board
Usually it will be a t4 250V in UK
You will have to take the fuse out and look at it as all TV's are different

If you dont have a multi meter to test the fuse you can turn up your stereo loud and touch one end of the fuse to the 3.5mm audio Line out and the other end to your finger, if the stereo buzzes it means the fuse still works


Goodluck

We were watching and it just suddenly turned off by itself. now, it won't turn back on.


Likely to be a blown fuse.
If it isn't a fuse in the plug it may be an internal one in the set itself (job for qualified TV repairer)

You may want to check the solid state fuse on the power suppy or which can be called the inverter. The fuse will blow and finding a fuse can be hard.
