Vox vt40 factory reset


Consider reading the Manual for this amp, it explains how to reset to factory with the VFS5 footpedal. Or with the power off ..hold down CH1 & CH4 then turn power on.. when the Bank & Channel leds start blinking.. then release the Channel buttons. Next press the Tap switch ... the bank & channel leds will change from blinking to lit. with in a few seconds it will enter preset mode.

No image. seems to be a led problem


POWER LIGHT FLASHES ONE SHORT AND ONE LONG FLASH.
What is the problem? THE PROBLEM IS THAT ONE OF THE LED's STRIPS IS BAD!

SHARP AQUOS LC60LE810UN RESET INSTRUCTIONS

1)Plug in TV to electric current First then wait until LED start flashing.
2)Press Volume DOWN [ - ] HOLD BUTTON.
3)Press Channel UP [ ^ ] HOLD BUTTON.
4)Press Power [ (') ] HOLD ALL three buttons until LED stops flashing and then release.

    ·This will reset the TV in order to fix the problem.
    ·THE FIX IS TO REPLACE ONE OF THE LED's. You need to open the back of the TV and you will also need to remove the front cover and panel to get to the LEDs. The TV will need to be placed facedown and on the backside. This is a 2 person job to turn the TV on its sides. Be careful with the white computer connectors (wide white strip) at the base of the TV where the TV stand sits. You will need to disconnect this in order to get to the LED's.
    Once you have the LED's exposed, you will need to unplug one by one by placing the new strip next to it until the unit turns on. You will have to use the RESET procedure above if the Power lite flashes. The Power lite MUST BE ON SOLID - no blinking in order to test the strips. The LED's will flash, but still one of them will be burned. Even if you stare and all the strip light-up, you will still need to check one-by-one!
    Once the TV lights up, your face will also light up with joy! Put everything back together and you are set. If you need the complete instructions which come from Sharp as to how to disassemble the unit, please send me an e-mail to LGTR61@YAHOO.ES. Please note I don't check this address daily, so a few days wait may take for you to receive the instructions.

    Where can you buy the LED's - try searching Yahoo.com or Google.com for resellers.

I have a Behringer PMP 6000 powered mixer. Channels 4 & 5 yellow overload light is constantly lit. No sound from either channel (just a faint hum when volume slider approaches max level...


There are NO "yellow" overload LED's period. The clip or overload RED LED's are just above the PFL buttons for selecting a solo channel. There are "yellow" signal received lights (level set) up near the trim controls. In normal operation these will light when signal is received. Here is schematic for the PMP5000 which is really identical for the 6000.
http://elektrotanya.com/behringer_europower-p0569_hca2400_sps1000_dpx_pmp-1280s_5000_sch.pdf/download.html This has part of the DSP and PS and the PA circuits.
Scroll down to "get manual" and click on it to download. Ignore other download links on the page.
Try turning off the Phantom power if it might be on... If that stops the hum, something is the matter with the bypasses feeding Phantom power to those channels... Possible problem might be shorting of one of the coupling caps at the preamp input. The PMH5000 drawings are more accurate at the input circuits. You will note that the level set LED's are the yellows, and the clip/PFL LED's are the red ones. I suspect that RF bypass caps such as C110 or C121 (example typical for channel one) might be shorted. This makes noise on the Phantom power line unbalanced and will get into the channel where one of these caps is shorted. Do a test: Plug a shorting jack that shorts the tip to the sleeve intot he inssert for the channel. With the LOW CUT button up, observe is the level set LED for that channel dims or goes out. If it does, then I supect you have a shorted RF bypass cap at the input..The next test involves driving a KNOWN balanced signal into the XLR jack and using a TRS in tthe inout 1/4 inch, test the levels with an oscilloscope to verify the hot and the return have equal amplitudes. I they don't, congratualtions you have to tear the main board out... lots of knobs and screws to access the inout circuits and verifuy the cause... it could ALSO be a bad transistor in the inout pair, etc...

My 60" lcd projection tv wont turn on sometimes and throws a lamp light, and if i watch tv for a while and turn it off it wont turn back on and throws the red lamp light


The buzzing sound you most likely hear is the ballast trying to fire up the lamp. I would say replace the lamp and yes they can act up at will. If this is the first lamp replacement ever then you are doing good.
