Having problems with your Flat Panel Televisions ?

No 3.4 volt output

\015 The power supply output voltages are present except for the 3.4 volt output\015

Answers :

The 3.4 should be for the microprocessor area and comes from the standby portion of the power supply-----that voltage should be on all the time so look carefully where it comes from---some sets use a op-amp IC to switch it on etc and others a relay---

Like a car with no power or voltage start at the battery working outwards.

With that voltage missing the set should have no operation at all.

Samsung PS42D7HD plasma TV has no pic no sound. Vs, Vg, Ve, Vscan, Vset volts are all correct. Heat sinks on X & Y boards are warm to the touch. RF In source and A/V In source have no output sound or pic. Remote Control buttons are detected by the TV as the blue LED flashes to each button press.

Take your scope and see if you have any activity on the LVDS cable on the main digital board as you press the menu button or the menu on the remote. If you do not see anything then replace the main board. If you do then the plasma displa ... Samsung Flat Panel Televisions

IC 860: pin 2 to 8 = 169.3 volts, pin1 to 2 = 8.7 volts (this voltages even after the TV turned off) pin2 to 4 = 2.69 volts (after TV turned off 0 volt).

I have an LG 26LZ5RV TV. I have connected it from the RF output of my Sky+ box (using a coaxial cable) to the "Ant In" socket at the back of the TV. The RF output on the Sky box is set to Channel 35 and the power is on. I know that the output is working, as I have tested it on an old portable TV with manual tuning. My problem is that I cannot get my LG TV to tune in to the signal, using either auto or manual tuning. I have used System "I" and tried setting the Channel to 35 then searching b

My tv (AOC LE22H037) automatically lowers the volume down to zero. it depends on what kind of sound is it outputting: during movie whispers or song's almost silent intros, volume gets lowered down. its annoying because i always keep missing the first 2 or 3 words of any line. it is like, if the tv "senses" silence or almost silent sounds, it shuts down sound output. But if the input sound is continous, like in the middle of the song or the shooting of a submachine gun, output volume remains cons

Hello, We have a HCD-HDX275 in the shop for no picture via Component output. It works fine through the HDMI. How do you change to the Component output? We have looked through the owner's manual, service manual, and Sony's web site to no avail. We have also disconnected the HDMI, hoping it would default to the only output plugged in. Still no luck. Thank you in advance,

Analog Audio Out signal has very high distortion. Signal wanes in and out, wanders from one channel to another, and develops high static. This happens when Audio Out is configured for Fixed Output. When configured for Variable Output, the signal is perfect. Output is being used with Sennheiser RS120 wireless headphone set.

The problem is more likely to be with the wireless headphone set rather than the TV. It makes no sense that the signal changes channels. The only difference betweent he fixed and variable output is whether or not the volume changes the output signa ... Flat Panel Televisions
