Not sure about the model number of your TV, but I have seen a few similar failures on 42" Phillips TV.

When the screen black outs, it's usually caused by a semiconductor with a short circuit. As soon the power supply detects the short circuit, it power off the display. The semiconductor can be a power transistor broken.

Horizontal lines are caused by a failure on the display circuitry. To repair it, the entire display needs to be replaced (making it an expensive repair), it may be caused by excessive use of the TV (let's say 14 hours working every day).

If your TV still under warranty, I highly recommend you to contact the manufacturer for assistance in repairs.

LG LED TV 42 inch 1080p 120hz horizontal lines and upside down picture


Sounds like a main digital processor board fault. In other words, its main board should be checked. This is a very skilled work, and a normal user can't do it with ease. Contact any expereicned service technician. Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product by anyone else could result in serious injury or death. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact the nearest service centre.

JVC PD-42DX6BJ plasma 42 inch black horizontal lines over the pic


Here's a link to order the original the JVC upper Y-buffer board and lower Y-buffer board for this model from a major parts distributor if needed:


JVC "PD-42DX6" Replacement Part Upper Y - Buffer Board (LJ41-02760A)

JVC "PD-42DX6" Replacement Part Lower Y - Buffer Board (LJ41-02761A)

Based on the symptoms: It is possible that the Y-buffers are faulty, which may require the replacement of the Y-sus board as well. You may want to get a local technician to diagnose the unit and provide a second opinion.

Vertical black line on the screen of my 42" Magnavox flat panel lcd tv


I wish I could post a solution, but I don't have one. I too have a Magnavox. About 6 months ago, once every 2 weeks or so, the screen would just go black- all but an inch or two on either side. Now, it seems like it's a weekly thing, sometimes every hour or two. As of tonight, it has happened twice in a matter of thirty minutes. It usually repairs itself if I turn it on and then off again but that's just not working anymore. If anyone has a solution, let me know.

Try the scan PCBs that run down the side and the connectors that hook them up to the rest of the system. That would be my first place to start.

Unfortunately I don't have service manuals for non-european models. What is the date of manufacture?

Are the solid horizontal black lines or colored lines. If colored lines there is a posibility that your Y-main, and upper and lower Y-buffers are bad. If black you have a bad plasma panel.

Phillips/Magnavox 9P5544C102 white raster and shuts down


This denotes a problem called blooming the horizontal lines you see are called retrace lines this is caused by the increase in anode voltage which could be caused by an increase in HV section current which trips the overcurrent protection dircuit and turns the TV off.If you do not have electronics experience I would suggest taking the set to a TV repair shop.
