sounds like you have bad capacitors on your main power supply board you can replace them if you know how to solder solid state electolitic componets. not hard but you need to know how. may want to just replace monitor

Hello,this is vertical IC loose connection. The vertical output components either a transistor or an IC is probaly got a bad solder joint. Also another possibility is the deflection pins. Buy soldering iron and solder from electronic work to repair the connections.Take the back off of it after it is unlpugged and disconnected from the computer and check the bottom of the circuit board for bad solder joints.I recommend you to be serviced by a technician.

lubbarlubab, Looks like you will need to get a power supply repaired/replaced in your unit. Before you call out the service guy, you should spend 30-40minutes at YOUTUBE and view some "LCD-TV repair" videos and also videos of "LCD monitor repair" and LEARN what are the most common components that are causing this plague of "BLACK SCREEN of DEATH" to disrupt your life. If the "cold-cathode-fluorescent-lamps" fail to light-up due to a failure of a single or multiple $2 parts on a power supply board you have a black screen!! This problem is also very common to LCD computer monitors. Try to view a vid by someone called "cal22583" who did his own repair to a Philips 42" or 50" unit. If this was of some help please rate on fixya.
Bye for now. 12fixlouie

My laptop screen goes blank from time to time and these are the reasons it happens. If you boot the computer with the screen open while on battery sometimes the screen doesn't connect properly, but closing and re-opening the screen fixes this. Also, if your computer has a video out connection such as HDMI or S-Video look at the F5 key and see if it looks like it might mention switching screens at all. If it looks like it does, hold the fuction (FN) key and press F5, give it 10 or so seconds, if that doesn't work, try it again a few times, waiting each time. If none of this gets your screen back, it is a hardware issue not a settings or user issue.

That sounds like a bad power adapter, a bad inverter , or a bad controller board.

When TV does not start, and sometimes you hear a clicking noise, that means that the TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

The key lock is a function that can only be reset with a remote. Go to www.zenith.com and under "support" you'll find product manuals. You can enter your model number and get the manual, but once "key lock" is on, you'll need a remote to change it.

welcome to fixya

it sounds like the back light on both monitors are going bad
it might be better to call a repair man and get him to look at it see if it is going to be worth fixing i think it might be better then buying a new one at the prices now days

i hope this helps out have a nice day:)

as with all old laptops, they fitted a range of wifi adapters inside them. You can replace it easily with something else for small change. We cant geuss which wifi adpater it might have although Intel and Broadcom cover a lot of options. You can easily run a PCI software inspector to Find the Wifi device and obtain the MAKER code and model number and look up the maker code in the PCI database. https://pci-ids.ucw.cz/ alternatively you can open up the cover underneath(or possibly remove the keyboard on top to visually READ the label on the wifi card and get the name of the wifi card.

if its a cathode ray display its got vertical scan problems then its the line timebase more than likely a resistor gone high value or a leaky capacitor take the board out and have a good look for burnt out resistors and printed circuit damage change any electrolytic capacitors
