The x or y sustain board died on you. It will be cheaper to buy a new TV and get rid of that plasma TV.

Possibly either the backlight lamp or its associated power supply has failed. Power buttons (mostly LEDs) have constant availability of low voltage (for some other circuits too) otherwise they wouldn't 'wake up' on command from a computer as some do.
The blackout could also be due to a failed main power supply so the incoming video is no longer being processed.

most times then not it's the capacitors on your power board that blew there for not supplying the tv with enough power if you open it up and check the capacitors it should be leaking some kind of liquid or the tops have bubbled up. its an easy fix cost>>2 dollars each

SOURCE: My MsPacman/Galaga upright has power but screen is black(blank)

I'm assuming this game cabinet was built in the 80's. More than likely, the monitor is an Electrohome GO-7. If this is the case, replace capacitor C511 on the monitor board. It has baked open due to old age. Usually, capacitor kits can be purchased for around 10 bucks, so you might want to replace all the caps on the board at ths time. Worst case scenario would be that the Flyback transformer has smoked (usually you'll see a crack on the side of the transformer), causing the horizontal output transistor to cook and also the smaller of the two pigtail fuses to blow. In this case, you would have to replace the Flyback transformer, the horizontal output transistor, and the small pigtail fuse associated with it. Remember to always discharge the second anode( the suction cup thingy on the side of the tube). It will hold a substantial charge on it. Also, if the small pigtail fuse is blown, you will need to discharge the large cap on the monitor board, or else it will knock you on your rear-end when you try to replace the blown fuse. Hopefully, you'll will only have to replace one cap. C511. If your game does not have an electrohome monitor, I can still help, if you provide the manufacturers info, such as Well Gardner model 7204, or something like that. Good luck!

SOURCE: 42" LG Plasma tv, no picture - black screen, but have sound.

Most a likely a problem with your Y-Sustain board which will then not drive the screen giving a black picture. The fuse on the board may be open circuit & need replaced but most likely you will need to have the sustain board replaced.

SOURCE: my LG HD tv screen suddenly went green. sound is

Hi,
I disagree with info provided, if screen of your LG lcd tv becomes green that means inverter board is working and lcd tv does not have convergence ICs.
Please unplug tv from ac wall socket for minute to get it reset, replug back in and turn it On and check its picture.
If still showing green screen then change input source with remote, if tv shows same green screen on all inputs that means its either lcd panel problem or digital signal processor got bad loacted on main board. Local tv repairman is needed to confirm and fix it.
Thanks.

LG X Power cell phone. I was using it, it suddenly froze...wouldn't restart or respond to any touch screen requests! Then the screen went blank/black and still won't restart! HELP!!!


Have you tried holding down the power and volume down buttons simultaneously to do a reset? It normally takes 10-12 seconds before it reboots. The LG logo should appear, then release the buttons. The Power X has battery connection issues and will do random shut downs as well. If it's shown other symptoms like charging problems you will need to take it in for repairs.

How to repair a tv LG plasma 60pv250


Sounds like your Power supply is still good. but maybe the board for the video is bad.. (maybe the main board other than power supply. If you do a search on the internet for "60pv250" and "board". you can find replacement parts. If you are capable or know someone with some electronics skills you should be able to see if any parts on the existing boards are popped (sounds like a capacitor went) and then buy the right board

try these settings, or just mess/tinker with it until you find one that is the best. But, search AVSforum.com for LG 60PV250 and you will probably find something that is helpful.
