Question about ViewSonic E70 17" CRT Monitor

No blue gun, all of a sudden

Hi Fixers, The blue gun on my E70 suddenly stopped working. Otherwise the monitor is perfect. Can anyone offer me a clue as to where to start looking for the problem? I'm a bit of a newbie, but yeah yeah, I'll be VERY careful of not getting shocked - I'd just like to know if its worth trying to fix it myself or if it really has to go into a workshop? Thanks, Gavin

    Hi Guest, my monitor is showing perfect picture in the Red/Green spectrum - pin sharp, high res, zillions of colours - all EXCEPT for Blue and combinations of blue. I've disconnected the power, checked the picture cable, had the back cover off, poked at all the internals [with a very long wooden chopstick - I'm not taking any chances;-] but still no solution. The only blue I ever see is when I shut down the computer, then the screen flashes a small intense blue spot in the centre before it goes dark.
    OK, so if there's no blue gun (Garfunkel01), then maybe it's some other circuitry or component that's faulty. I just wondered if it might be a simple fix...
    Should maybe raid the piggy bank and buy one o' them LCD things instead!

100,000? At that rating the monitor would be giving off x-rays and gamma rays. Its more like 25,000 volt, plus its easy to discharge the tube, don't discourage him... Gavin2, is your monitor still not working?

Cant be a blue gun, there is only one gun in these monitors. Check your cable, wiggle the cable at both the comptuer and montior ends, if this monitor has a changable cable and wiggling it works, replace the cable. otherwise you'll have to take it somewhere or get it replaced.

    it's worth having someone professional look at it if you need to open it up.

    There are extremely high voltages involved with CRT monitors and tv's. I would not reccomend opening it unless you know what not to touch.

    (100,000V+)

    be careful

Sony 43"/projection (older) suddenly after 18 years has a snowy and less than perfect picture. It will "pop slightly" and the picture will come back to perfect. Any clue?
Your picture tubes are failing. There are no parts available for this TV and your money is better spent on a new flat panel. That is the grid guns starting to short out.

My monitor colour has changed to yellowish
The first thing to try is to make sure the video connections both at the monitor and the PC are secure. A number of color image problems are just a loose connection. Make sure you remove the connectors and then reseat them when you do this.

My Sony Moniter suddenly turned to a bright yellow
If the display looks normal other than being yellow, it's missing blue.

This may be because of a bad cable. Sometimes the wires inside break from flexing. Try wiggling the cable (as mikeslab suggested) at the end where it connects to the computer. Also check the plug for bent pins.

It's more likely the monitor has lost blue due to solder connections to the blue output transistor or transistor failure, or that the picture tube itself has gone bad and the blue gun has quit. Tube failure is pretty rare. I've seen many cases of bad connections and transistors, though.

If the cable and plug aren't the cause, you can have a service shop check the monitor and give a repair estimate. But if this is a 17- or 19-inch monitor, you might just want to replace it. New LCD's are $150 or less. To repair yours would be around half that cost already, possibly more depending on labor and parts costs.

Black and white only
Well - it's fixed - but no thanks to anything I did.  It's just all of a sudden working fine again.  I tried three different dvd's the other night, and all were black and white.  But last night the same dvd's were back to colour.  Who knows?
But thanks for asking.

LG L194WT Monitor suddenly stop working
it is probably indicative of a switched mode powersupply trying to start then seeing a short and then trying to start again...this will cycle continuously until fault is rectified..any component that can drain the powersupply is the culprit...you need some way of detaching the powersupply from the load (monitor) to see if the power supply its self is the cause and also check if there is a loop back (a pulse) for continuous running.

for whatever reason you have lost your blue gun. it could be a matter of an adjustment or a defective component in the blue video driver. take it to have it serviced.

E70 CRT Monitor. The settings adjustment screen pops up regularly and obscurs the display. It is inaccessable even the pointer doesn't appear over it. I cannot exit it. Only way is to switch monitor off and on again. After a few minutes or seconds back it comes. Tried reinstalling software drivers. Went to website but only drivers available were E70fm. Mine is a nine year old CRT but is still working fine. Only needed a fuse replacement once.
