Have you checked your fuse? Will the relay click when you press power? You may possibly have a bad relay or the bridge rectifier diodes could be open.

    have you checked the voltage regulators to see if your stand by voltages are present? If the stand by voltages arent being produced you have a dead regulator in that supply

My 46h84 turns off and i have to unplug and replug


Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

WHY DOES MY TOSHIBA TZ61V61 loose picture but not sound. Unplug from power wait a few minutes plug it back in and it works


The vertical deflection has stopped which cuts off the picture tubes to prevent burn in. Check the vertical output or the deflection board may need replacement.

Why is my toshiba 46h84 picture getting darker than before? Its becoming harder to see darker scenes in movies


It sounds like your lamp is getting close to the end of its lifespan.The lamp is what gives your screen its brightness.With time they start losing this brightness.If you were to wait to replace it till it goes out completely you would have a black screen.You can purchase a quality lamp at discount-merchant.com

No picture but sound on Toshiba 46h84


If you feel comfortable enough, you can try replacing the pico fuses on the power supply board. Test them with a multi meter very carefully.. these sets have up to 5000 volts and care should be taken, even by a professional with the back panel removed.
