Question about Toshiba 43H70 43" Rear Projection Television

Flickering of screen (comes and goes) and weird DVD/reception problems

Okay I bought this tv used, and everyhting was fine until I started getting this weird black flickering lines on the screen. The picture is still fine and clear. The flickering comes and goes. Sometimes it's there and then won't come back for weeks, very strange. It might be a connection problem inside, here's my next issue. I had a dvd player plugged in the a/v cables, it worked fine and then all of sudden i got sound and no picture, so i bought a dvd player and it worked fine as well, then the same thing happened. I tested the new one on my friends tv and it works fine. i don't get it? lastly, i think my coax cable things are loose. sometimes the reception goes blurry/distorted and i need to jiggle the coaxial cable thing. how do i tighten the loose connection? I'm sure this all connected, but i don't want to open this thing up and break it. so, i need help figuring out why my tv flickers black lines at times, dvd players that work and then don't, and how to tighten the loose coax/coaxial cable connection? Thanks.

    Hyper board? sounds complicated? can it be fixed? where do buy one of those? the set is like 10 years old.
    It works great just sometimes it has it's problems.

    I think I can probably squeeze another year or 2 out of the set and then junk it. The thing is it's so goofy, because for the most part it works great, awesome tv. i only paid $200 for it.
    Thanks.

    There are bad capacitors in the set also i bet, probably not a fix that would be worth repairing, as the board is about 250 to 300 bucks, but the problem is they are no longer available.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

TH-42PX75U horizontal lines (flickering black and white)


The controller board for the screen is going bad. check shopjimmy.com for replacement parts. It's not a difficult job to do. Once the back of the TV is removed, you'll see it near the center of the screen.

HP Pavilion g series g7 black screen but occasion flicker shows it is up and running.


Hook a spare monitor to the video output usually on the back, if picture is okay! the problem lies in the inverter board, "just below the screen" or the backlight behind the LCD display, or the video cable from the screen to the motherboard has come loose from the plugin. But if both show the same symptom it means the Video Graphics Card is defective, normally built into the motherboard.

Tv repair


You don't have to buy a new tv, it is a fairly simple problem, your vertical ic is blown, and it could be the powersupply to the vertical ic also. To verify, slightly increase the screen voltage, and a horizontal line will appear on the screen, if the voltages is okay, change the ic, but first try resoldering the ic pins. Good luck

TV picture flickers


If your DVD player is separate from your tv, you might have a loose cable plug or connection. Depending on the type of flicker you have, a vertical circuit loose connection would cause this. If you could connect it to a cable or antenna it might tell you where the problem is located. A faulty circuit in the DVD might cause this too. Stargazer
