did you use the external VGA port and then not use the lenovo
hot key to turn that on Fn?
remove the huge battery first and run on AC pack now? only?
screen dead no text? this is bios, must never be dead.
no lenovo, icon, at power on this is bios.
fan dead silent.?
is the HDD (ear to casing) dead silent , prooving dead HDD.
run HDD tests? if heard to spin
if all above is dead that means power is gone.
try new AC pack for $8 cost?
or use voltmeter on yours see if it is dead? pack output pins DC.
WHY DOES THIS SEARCH SHOW. The Viewsonic VSR220 no such thing.?
Turn the monitor around, 180 and see the TAG sticker with real model told no PC told , what PC is this?
this ? VSD (D key is next to R) so huge typo"?
yes that is a PC (android) but can do monitor like duty. too. it needs service. if screen is dead, it has power problems as the screen must at least show a viewsonic splash as power is turned on. try it on a 2nd room AC power jack yet:?
if in warranty take it back to the store or call viewsonic for help. the android PC can use an HDMI cable to a PC and works as a monitor.too. the manual states " 4.5 Connecting to HDMI-compliant Devices via Micro HDMI Input HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed digital audio/video data. You can obtain the best user experience for video playback and gaming via HDMI. VSD220 is equiped with a micro HDMI input for connection to an external HDMI-compliant device. You can connect your PC, notebook, Blu-ray player or any other HDMI-compliant device to VSD220 for high-definition video display."
Hi It seems your TV set has a problem in the R ( red) gun in the RGB circuit. It means that the red color circuit is missing. To fix this fault it requires some knowledge in electronics and is a good challenge for an electronics hobbist. Generally is a faulty RGB output transistor on the small board attached to the CRT neck. To trace it, mesure the voltages in the colector of the three big transistors on the mentioned board. One of them may have low voltage or even none. That is the culprit. Replace it and you are done.
It may not be dead yet. Does it supply output? You have not mentioned. It would be considered dead if it does not give any output. Is the battery fine? If the battery is fine and there is no output then it may be dead. So, check the battery for any sign of life. Check the output. Check output with it plugged into mains. If all are negative then it is dead.
Laptop is dead. How to troubleshoot the problem. In this post I’ll explain how to troubleshoot a dead laptop and find the problem. The following troubleshooting tips are not model and brand specific, they should work for most laptops. Let’s take a look at two different scenarios. Example 1. The laptop is absolutely dead. When you plug in the power adapter and press on the power button, there is no signs of life at all. The laptop will not make usual noises, LEDs will not light up, the fan will not spin, the screen is blank and black, etc… In short, the laptop is dead. What you can do in this case? 1. Make sure the wall outlet is working and the laptop DC adapter is getting power from the outlet. Try another wall outlet. 2. Test the laptop DC power adapter, make sure the voltage output is correct. You can test the DC power adapter with a voltmeter. 3. Let’s say the DC adapter is fine and the adapter outputs correct voltage. In this case unplug the power adapter from the laptop, remove the battery, wait for 1-2 minutes, plug in the adapter and try turning on the laptop again. OK, you tested the adapter and it’s bad. If you decide to replace the original DC adapter with a generic one, you’ll have to follow this rule: The voltage output on your new adapter has to be exactly the same as on the original adapter. The amperage on the new adapter could be the same or higher. If nothing helps and the laptop is still dead, apparently the motherboard is fried or there is a problem with the DC power jack. It’s possible the DC power jack is broken and the motherboard is not getting any power from the adapter. In this case you’ll have to disassemble the laptop and replace the power jack. Example 2. When you plug the DC power adapter and press on the power button, the laptop starts making normal noises, the LEDs work properly but noting appears on the screen. The laptop will not start. First of all, take a closer look at the LCD screen. Look at the screen under bright light. It’s possible that the image is still on the screen but it’s very faint. If there is no image on the laptop LCD screen, test the laptop with an external monitor. Connect an external monitor to the VGA port on your laptop and turn the laptop on. You can toggle video output between the internal LCD screen and external monitor by pressing Fn and F4 keys simultaneously on HP laptops, Fn and F5 keys on Toshiba laptops, Fn and F7 keys on IBM laptops. Other laptops may use different key combinations. Let’s say the external monitor works fine but the internal LCD screen has no image at all. If that’s the case, your problem could be related to the LCD screen or the video cable. Also, make sure the video cable makes good connection with the motherboard and the LCD screen. Try reconnecting, reseating the cable. In my case, both internal and external monitors were absolutely dead. Neither of them had image. That means the problem is not related to the LCD screen or the video cable. From my experience I know that this problem could be related to the laptop memory. Try reseating the memory module, maybe it’s not making good connection with the memory slot. Try cleaning contacts on the memory module with pen eraser. Try moving the memory module into another slot. Try replacing the memory module with another known good module, it’s possible that your original module is dead. If you have two memory modules installed you can try removing them one by one, it’s possible that one of the modules is bad. Try installing different memory modules into different memory slots. In my case reseating, swapping the memory module didn’t help. I was pretty confident that my problem is not memory related and I moved on. Try removing battery, hard drive and DVD drive and turning on the laptop without these components. Also, try turning on the laptop with an external monitor when the video cable is unplugged from the motherboard. If the laptop start with video on the external monitor, apparently there is something wrong with the laptop display panel. Finally, disassemble the laptop and removed the motherboard. 1. Motherboard. Like on most laptops, in my case the video card is integrated into the motherboard 2. CPU with heatsink and cooling fan. 3. Known good memory module. 4. The power button board witch you need to turn on the system. 5. Working DC power adapter. Still cannot get any video on the external monitor. The system turns on, the cooling fan starts spinning but there is no video. At this point I’m 95% sure that the motherboard is dead. CPU failures are not very common, so it must be bad motherboard.
take an ohm meter you can buy for ten bucks at radio shack put the volt meter on DC volts plug the charger into the battery charger end the black lead goes tothe outside and the red goes inside, set the meter for 12 volts dv and mesure the voltage. read the voltage output on the battery charger transformer see if it's within a half volt if not the charger is bad, if it's ok then use rubbing achol and a q tip to clean the battery connectors on the computer and the battery itself, if you do not get the light then pull the battery out and hold the power button in the on postion and hold the enter key for 1 minute and try again, if the lights do not come back on your battery is dead, if the computer will still boot with the battery then the charger is working if it won't boot up the battery is dead. Got it?
