Jvc av-48wp74 48 in widescreen green projector problem


Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

From what you're describing your focus block is probably failing JVC p/n#129P059050. It's probably also very vibration sensitive. They're about $80.00 dollars and they are also interchangeable with the Mitsubishi focus pack p/n#920p016010. Not a difficult repair - we do about 5-6 a month. Real easy in-home repair. Hope this helps. Bill

There is a 5, 9 & 12 volt dc regulator on the chassis that could be causing this. Three legged transistors on small heat sinks. I f you look at the chassis from the rear of tv, is two boards.The one on the left has these reg. transistors. Usually the 9v regulator is bad and a 35ufd @ 50v capacitor near it is bad. From the tuner as ground check the third leg on the regulator for less than 9v dc.

Hitachi 51f500(flicker+warp)


Most likely bad convergence IC's! Location numbers should be IK04 and IK05. Generic numbers STK392-110.
