Question about Philips Magnavox 27MS343S 27" TV

1 Answer

Magnavox 51MP6200D/37 Red picture on top, escentially same blue picture on bottom with arc between the two pictures. One person told me it sounded like the Conversion Board needed to be replaced. Local shops (within 45 miles) say the TV needs to go to their shop for any repair. I would rather not, if possible.

Screen is bowed on top and bottom.

Projection sets have two very common problems outlined below.

The first common problem is 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. The TV can also shut down when the convergence starts to fail.

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, RCA and others.

You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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

Did you use the Automatica Convergence to try and straighten it out? If that does not help, you can manually adjust the convergence.

You will have to give the set out for service. This is not something you can service yourself.

This can be some failed components in the CRT bias and drive circuits, or maybe a CRT has failed. This has to be determined by taking measurements and doing some tests.

I believe that your set may have been manufactured by Philips.

Magnavox TV Model FP4640

The picture tubes in these models (red, green and blue) use a liquid coolant to keep them cool. In this set usually the blue and green fluid will become contaminated which has a major impact on picture clarity and brightness. If you take the screen off and look directly into the lenses you will see directly how bad the fluid looks. The Red usually is not affected by this problem.

The buzzing could be a noisy coil or possibly a high voltage leak. There may also be some leaking fluid involved in this as I have seen fluid gather around the high voltage cup (underside of the tubes) and cause the high voltage to arc a bit causing noise as well.

This repair is not for the faint of heart as it involves removing the affected tubes, disassembling, draining, sanitizing, reassembling, refilling, reinstalling and realigning them. The glycol based fluid is messy and it's easy to get into big problems if there are any leaks, as the leaks will usually end up on the main pc board. Our shop charges about $350 for this repair.

Arcing blue sparks internally

the thing which you have seen is resistance not the capacitor. whenever that goes hot or arcing it is due to heavy short ckt in tv. as you are not much aware of tv technology please caall skilled person to do it for you. please now do not start again unless it is repaired. otherwise it may be problematic. good luck.
