The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Hi, Mary.

This sounds to me like it is a bulb issue, and not something worse, like failed capacitors.
If that is the case, then yes, it is worth repairing it.

You need to get the old bulb out, either by removing it yourself, or by having someone take it out for you, and the take the old bulb to Fry's or BestBuy.

They both keep tv projection bulbs for flat screen tv's in stock.

I hope that I've helped you understand what is going on, and that it helped.

Have a nice day, and good luck.

PANASONIC TH-42PX60U 42 - half of screen not working


I had the same issue. I am going to replace my scan buffer boards. The upper half of mine works but the lower half is black so I would replace the lower Scan buffer board but in case of future issues I have ordered both upper and lower for $44.
The scan buffer boards are fairly simple to locate. Open up back of tv there are two biffer boards identical. The item or product code on them contain letters either SU or SD (Scan up and Scan down)Look up tv parts and item code you will find a place to order or just get the 1 800 number from tv manufacturer.

Samsung plasma TV, half screen is blacked out


Well, as per my last posting, I thought I would share. The problem of the bottom half of my 42 inch Samsung Plasma blacked out - meant a trip to the local TV repair shop. I have to say, they were great. I took it in and they were able to fix it after replacing a part - had my TV back in about a week. Cost was approx. $300. This was well worth it, considering how much I had paid for this TV only a few years ago. I had the repair done last month and so far, it's been great. Sorry, but I can't remember the name of the part.

Picture problem, half screen blank


On a plasma there are 2 buffer boards, upper and lower, it all depends which half of the screen is on as to which buffer to replace, the buffer boards are located usually on the left hand side if you have the back off the unit. You maybe able to reseat the ribbon cables and get the video back up
