My Zenith TV model IQC60H95W has no picture and no sound. When you turn it on you hear a clicking noise. I keep hearing it may be the flyback transformer.


This is also where I would recommend starting to look. I have a tip at which should help you localize and repair the problem.

Thanks for using FixYa and for the great rating.

I have a 1994 zenith big screen the picture is showing really dar

It could be that the picture tubes have gone down on emission, there is a prcedure that can be tried to bring up the overall brightness but it is just possible that you will loose some picture quality. If it's a 1994 projo tv i am thinking of the three crt system, a gray scale alignment would probably correct the dark condition in your picture, again depending on how far gone is the emission in your picture tubes, if your projo tv is the dlp system, the bad news is that you could be needing some light engine repair. The color adjustment is possible with the availability of a service manual or in the case of the dlp system, light engine repairs or replacement are available from some on line stores.

I have an old 25" zenith, picture is great; but when I play a video with a lot of action scences . . . the picture refresh screen appears not to be able to keep up. Is there a solution to this problem...

The tv is definitely old, and this tv generally has a weak picture by now, creating red streaks pulling to the right. It may also have green or blue streaks...this is called frosting. Replace this set and see the difference!

R49W36 that cuts off and on

Hi, your other option is to talk to other repair shops in your area, or call zenith (LG) and ask for repair shops they recommend, tech u talked to wants the easy way out rather than troubleshooting the board to find the 1,2, or 3 parts that are actually bad, be advised that the good old zeniths are now owned by LG industries and contrary to the tv commercials that tell you "LG" = lifes good, it actually stands for lucky goldstar the korean outfit that has owned zenith for quite awhile now, sad but true, video-tek

Picture Greatly distorted all of a sudden by many yellow lines

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.

Picture Fades

The more you play set the longer it will last, it sounds like you may have poor connections, cold solder joints try soldering around flyback transformer.
