Sound but faint picture


Hi Neil,
It a case of backlight failure. Most probably the inverter board has gone bad.
Good Luck.

Samsung flat screen tv no picture sound only, I have checked all connections and remote still same problem.


The T con board is faulty. It is the board with flat ribbon cables going to the bottom of the screen. It is not hard to replace this board. You can get one from here:

No sound and no picture


The green indicator merely lets you know that power is getting to your TV. The absence of picture and sound could be due to power supply failure

Theres nothing on the screen but the audio works. when i turn it on there no picture showing. the screen is just black


The failure with plasmas when the TV turns on but doesn't show any video only audio, the failure is with a defective Ysustainer board. The hybrid IC that is located under the aluminum heatsink becomes defective due to the excessive heat when the TV is functioning.
I would suggest that if you're fixing the TV yourself to measure the voltages from the power supply to the Ysustainer board to isolate the failure, if all the voltages are present then check any fuse on the Ysustainer board first. If any fuse is blown, then the Ysustainer board will need to be replace. Most service techs will replace 3 boards when this failure occurs. The Ysustainer, Zsustainer and main digital controller boards.
Check this link to find parts to fix your plasma.
Let me know if you require further assistance.

Sony tv mfm ht75w tv doesn't stay on, works for 10min sometimes,, other times only sec. i opened it all the caps seem ok, any ideas


Please clarify whether the entire tv powers off or only the screen turns off and you can hear the sound so that we can continue with the diagnosis. Sony LCDs are notorious for backlight inverter failures.

Picture goes to a single horizontal line.


Your problem is due to failure of the vertical scanning circuits in your TV. This is quite common and is caused by aging components. Generally drying out capacitors
You got to be careful not to leave it on too long when the picture collapses, it will burn a permanent line across the screen.
If you are an electronics expert you can fix it if you get a schematic. If not please don't attempt to reapir it yourself since there is high voltage in side the TV.
The problem may get worse with time.
