SOURCE: blink s blue light envision g218a

Hello,

The blinking blue light indicates your power supply has blown out. The heat buildup in the case has caused parts called capacitors to blow and short the power supply causing the blinking. We offer a repair service for $30 plus return shipping. If you wan to do the repair yourself you will need to open the back of the monitor and look for the bulging capacitors. To see what the bad capacitors look like go to our site at: www.ccl-la.com Replace any bulging caps that you see and you should be back going. You will need to use high temp capacitors marked 105c. If you have any questions about the repair or repair service just let us know at the address below.

I hope this helps, If so please rate our solution.

catamount309, This is only a guess, but unit may have internal "switch-mode-power-supply"/"CCFL inverter" board problem. When screen goes BLACK, is it also BLANK? If you can see WIN-desktop with aid of bright flashlight 1 inch from screen, then SMPS is in partial shutdown mode. If you see nothing, then SMPS is in full shutdown. In either case, Technician will need to repair the SMPS/CCFL inverter board. If KNOWN GOOD monitor works with PC, then you know 7100e is bad. Do you know and understand how the new energy efficient screw-in curlie-Q light bulbs work? If the "electronic ballast circuit" not working, then it can't light-up the CCFL tubes on the reverse side of LCD panel then you see black. Do more reading in my fixya profile for more options open to you. Do your research first!! Hey, reading is free!!!

Above top, is your user manual, below is your service manual.
Have a look below. it is a training manual, it will help in understanding and troubleshooting.. Just Google training manual..

I applaud you for wanting to have a go, but you must make sure that you are starting in the right place, That is The Power Supply, as, if, that isn't right nothing else can be. But you simply cannot do anything without a Service Manual. In this it has everything one needs to repair the set. OK if it is shutting down, after that amount of time, of working and then faulting, then it is most definitely a "Thermal" problem, the way we "Find" problems such as this is "Freeze Spray" you use this on each component that is suspected of being the "Culprit" and you will soon,find that errant component. Now also not every fault is a Capacitor, I see many, many people that think, that Capacitors are always the "Culprit" now while that may be true in a few cases, a faulty Electrolytic Cap, or ordinary, Cap goes faulty, this is only a SYMPTOM, something has damaged those caps causing them to "Fail". One MUST always find the root "Cause", otherwise if you just treat, the SYMPTOM, the "Cause" will just make the "Symptom" come back, in short order, as the prime cause still, hasn't been fixed., Now Capacitors hate AC ripple, or Over Voltage. That's it. Oh.. and Heat, if these Capacitors, are too close to a Heat Source, then that's a prime cause of failure. Resistors, hardly ever go faulty, and if they do, it is generally obvious. However it doesn't hurt to check values with our Multimeter. Remember though resistors are made, with up to 20% tolerance from stated value, as such, are not too critical, unless in Timing circuits etc. Always check, the Values, of resistors, as with any other component, with the power OFF. Now Diodes especially "Zener Diode", are another thing to check, those and ordinary "Signal Diode" should always be suspect. next we have Transistors and IC's. The Transistors MUST ALL be checked to see if they have a good, "Junction" this is done, with our meter set to "Diode Test" and usually are about 0.6 to 0.7. With IC's you must check, voltage levels, or Logic Levels, going in and out, have a look at the circuit diagram, and it will tell you what they should be. It is a good idea to always measure the Power Supply voltages, see if a "Rail" is Low, that will be because some component has gone somewhat or all short circuit, to Earth, now, if the "Rail" is Higher, suspect an "Open Circuit" component, like a Diode, or Transistor. The voltages expressed in the manual are spot on, ANY variation MUST be investigated. I have been doing all this for over 30 years now, and I do indeed wish, we could have a set of "Symptoms" and be able to say.. "Oh that's the so-in-so and replace this" however unfortunately this although does happen, most "Symptoms" can have literally tens, of "Causes" all often "Interlinked" One simply has to do a methodical troubleshooting procedure, and always think, "are my Voltages Correct" as this is how, you Fix the problem, by making them so. Keep up the good work. If that link above doesn't furnish, a Service manual, it is imperative you get one, even if you must pay for it. It will pay for itself in about 2 mins.
The Tools you will need are A SERVICE MANUAL a Good Multimeter, a Signal generator, a Signal Tracer, pref an Oscilloscope, Soldering Iron, De-soldering iron, Probably, too, A SMT Hot Air desolderer (for the Surface Mount IC's), Compressed Air, An Anti-Static Wrist Strap, (MOST IMPORTANT, to prevent ESD), Cutters, Screwdrivers, sometimes, Torx, drivers too. Tweezers, are real handy, a magnifying glass, or eyepiece, a good strong white Light. OH, and you MUST have the original remote control too, (Sometimes one must obtain, purchase, a special "Servicing remote") as one needs this to "Program" the Computer in the TV, after, and during servicing, and to be able to put the TV, into "Service Mode" too.

it is my professional opinion though that everyone should take their units to their manufacturers approved service center, contacting a head office, of your unit & getting an approved service center is just SO important, even worth the extra to ship it, you see, at those places, the Engineers, are trained on the equipment you have, they usually have parts on hand, and do the job quicker. Anyway do that and get a "Quote". This way, at least, you'll know weather to repair or replace.

check power and also check the capacitors on the power supply because this is a common symptom of a power supply with bad capacitors on it from heating up.

Screen goes black after it on for about 2 seconds


john_paul57, Yes it happens that way! Must be that dam "switch-mode-power-supply and or cold-cathode-fluorescent-lamp electronic ballast circuit called an INVERTER circuit. TOO bad. Atech will need to evaluate and make repairs to light -up your fluorescents again. Here are some points that may be of interest FYI Goto YOUTUBE and view some video clips (8-12min ones are the most informative) of "LCD monitor disassembly" and "LCD repair". After viewing info about BAD capacitors or failed electrolytic filter capacitors, and other things that relate to WHY LCD monitors have BLACK screens, and SMPS's that are in constant SHUTDOWN mode trying to save themselves from a total catastrophic nonrecoverable failure. (smoke,fire) Sometimes you can tell if the SMPS is in full or partial shutdown mode by shining a bright flashlight 1" from the BLACK screen and if you see the Icons on the WIN-desktop it is only in partial SHUTDOWN. Yes, lots of TECH types visit second hand resale shops and buy up all the BLACK screen monitors for $5, put $6-$8 worth of caps in and resell them for $50-$75!!
Well I've told you enough to get both of us in trouble now! Get back to me if this was of interest to you and would like to attempt a repair or you need more options as to having the unit repaired. I'm louie12fix on fixya, BYE for now. If this info was any help please rate this response on fixya.

Our 52" widescreen LCD TV just quit working.


This set uses a lamp ( not picture tubes ) The part # is TS-CL110U. Almost certainly it is bad. They are easily obtainable and you can easily change it yourself.

Monitor started to flicker then went blank


I have a envision professional series and I love it, but I will get to the point.
I recent ly received a Envision EN9410e monitor, had the same problem (flickering screen then turned on, then off then on then blank). The problem is bad capacitors. There are 7 electrolytic capXon capacitors that will need to be replaced. You should see if the caps are bulging or leaking, if so replace. As known by many replace with the same capacitance and voltage. There are a few incidences that the capacitors where replaced and the problem wasn’t solved; this is because the cap problem wasn’t taken care of and damage occurred to another part of the monitor. The back light is a Royer oscillator (cool things) and it uses two smd mosfet transistors. They are on the green side of the circuit board near a big control chip (they each look like a off rectangle black square with eight pins) you need to see if there is any carbon or chard residue between the pins or burning smell from them, if there is you need to remove the transistor and do some board repair then ether put a new transistor or try the old one. No offence to the people at Envision but not smart putting the drain, gate and source so close to each other under the chip where there is such high voltage! Hope this helps.
