A matter of broken electric electric capacitors inside your TV.

Solution:
- Open backplate (loads 'o screws and ruins your warranty)
- Remove the connectors from the center circuit board
- Remove the circuit board via 4 screws located on the side
- Remove plastic on the back of center circuit board
- Remove cooling plates of circuit board
- Look for bulging capacitors
- Solder these out
- Go to local radio shack, take the capacitors (and spend about 5$)
- Resolder new capacitors
- reinstall circuit board
- Hook everything up and close the back plate

Voila! (at least, this worked for me)

Samsung Mod. LN32D430 When I turned on Sound and picture is Ok, When I tune Sound ok but not picture


Hi,
Is very possible that your tv has a capacitors issue on the power supply. You can easily open the back cover and visually inspect if there is any burned capacitor. (Google burned capacitors so you can have an idea how they look like and you can easily recognize them if you see one on the power board in your tv).
If capacitors are ok, then you might have a defective inverter board.
All these parts are still available out there and are very affordable.

Good Luck!

After a power surge my tv had a picture but no sound when the lights came back on.


Check its speaker first. If found OK, check and replace damaged component/s at its audio output stage circuit. Contact any service technician. If you wish to get some details; check the site linked here.Viewing it in "Mosaic" will make surf easy.

My Magnavox TV give sound but no picture. When I turn it on the light in the bottom right hand screen goes green, then flashes to yellow and goes back to green. The screen does not change it is constantly...


You need to replace your backlight inverter.

Check that all voltages are coming from the power supply as they should. The power supply will be stamped with the correct amounts, and you just read with the multimeter to confirm.

After those check out ok, you will need to replace the inverter to "light" your screen again.


You can hear sound because the tv is ON, but the inverter isn't lighting the screen!


Hope this helps, please rate!

Hi my rca tv model l26wd23 screen light up but there is no sound are picture


No sound but has pictures? (no sound are picture ).

Let verify first to narrow down to where the problem can be. First, make sure the MUTE or SAP function is not activated, and then check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks (Red and White) to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.

My samsung TV won't show any picture/sound.


When the TV is on, need to check the back light is on(go back side & look into through)

If the back light is on -- need to exchange the Main Board
no back light -- exchange the Power Board --- 95%
exchange the LCD panel --- 5%(inverter)
