Question about Televison & Video

Dropped Magnavox TV

I got a TV from a friend who's son had dropped it. The TV turns on and the sound is fine. The picture comes up with about 1/4" wide stripes of red green and blue in a wavy pattern over the picture. You can see the picture OK but have the bands of color over it. When it would normally have white text (say menus) they show up as rainbow colores letters. Is there something simple to fix it or is there some particular damage I should be looking for that would reflect these symtoms. I'm a mechanical engineer who likes to tinker and should be able to track down any components you can describe to me.

Here's a picture of what the screen looks like

Well, with everything I've seen about the TV basically being best off thrown away due to repair cost - as a last resort, I decided to simulate the TV being dropped the other direction to see what it would do. I banged on the side and watched the direction the distortions shifted and then hit it at different locations until I determined the direction it needed to shift. After a few firm hits, there was a light click sound and the picture was perfect. This may have been a fluke and may never work any other time but if it's going to be thrown away anyway it's worth a try. I figured I might get it a little better to use as a garage tv but it fixed perfect with no distortion, rainbow, or anything - Perfect picture. Probably just lucky this time.

I dropped my TV screen hit the floor, it works, but is it safe to use? I heard it could be a fire hazzard?

when plugging in some chords to the back of set, the sharp tv fell forward on its screen down about 3 feet onto carpet. the sound and picture are there but a rainbow of color (similar to other ?? pictures, not as thin, broader rainbow stripes) prevails on the picture.

The shadow mask in the picture tube has shifted from being dropped. The only way to fix the set is to replace the picture tube, which would cost more than buying a new set.

Power light but no picture or sound

Hi!
My name is Chris.
I have this Phillips Wide Screen TV that didn't have or come with a remote, so I had to go out and buy a universal remote for it today from a BIG W Store. I'm having some technical difficulties & problems with switching and turning it on, but as I use the universal remote to turn on the TV, I'm having a bit of a slight problem with it turning it on, Ok, Yes, it works and Powers on, but there is nothing showing or giving me the indication that there is no picture or sound showing up on this Wide Screen Phillips TV, But there is a little red & green light at the bottome right hand corner that keeps on flashing red when ever I use the universal remote to switch the power on. Is there a possibility, that i can get some help on here, to help me out with any suggestions, is to why I'm not getting any picture or sound showing up on this TV with this universal remote ? Is there anyway that i can maybe get some help with this to help me out with solving my issue with the Phillips Wide Screen TV ?

42" Panasonic Plasma - Vertical red stripe 6" from left side

We originally had a red stripe roughly 3" wide running vertically on the ride edge area of our Panasonic 52" Viera plasma tv. It has now been joined by a solid black stripe of the same width running from the top to the bottom. Living in Germany and purchased at local PX long enough ago that the warranty is likely expired. Now what?

2" vert. red stripe

I have worked on many Vizio televisions under warranty and what you are descriping is often a result of the X boards going bad. If the telelvision is under warranty, contact Vizio at 1-877-MYVIZIO, if it's no longer under warranty, the cost of repair is probably going to be more than the cost of a new tv unfortunatly. I always recommend buying the extended warranty's with these televisions.

The lights on but no-one's home - no picture on TV

Sounds like you have a short somewhere, probably the Horizontal Output Transistor. If there is a fault the led you mentioned probably should be blinking. You probably are going to need a tech to look at this as it is a very complicated process of elimination.
