Projection sets have two very common problems.

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. 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

No picture just sound


Model listed here is rather old so first suspect would be bad solder connections on power board or elsewhere. Some of these are also prone to Glycol issues, coolant from the picture tubes leaks and gets onto a board and causes failures of almost any kind depending where it leaks.

54 inch Akai Tv makes brief siren noise when plugged up.


I have had a few of these with similar symptoms. In one case the set had a coolant leak onto the circuit board. The way I found the problem was to unplug the power and removed the front cover.(most models you can remove speaker grill and access panel) Make sure power is unplugged. When I looked in using as much lighting as possible I was able to see small puddles of coolant that had dripped onto the circuit boards from the picture tubes above. The other one as I recall had an arcing picture tube which caused a screeching type sound seconds after plugging in, then it would go into protect mode and just have a blinking light. I'm sorry to say but in both cases it was deemed unrepairable due to expense or lack of parts. Although, in many other cases I was able to clean the leaks and circuitry to restore power. Keep in mind this is just an educated guess. Good Luck, Russmann.

32" TV fell over onto carpeted floor and won't


It's probably a write-off. The circuit board inside has been cracked so that some of the copper traces that connect parts have broken. This commonly happens around the area of the horizontal output transformer, which is heavy. The shock of the fall causes the transformer to bounce and breaks the board. Other areas too may have been damaged because of flexing. And worst, the picture tube can be damaged in a fall, so it either doesn't work at all or shows permanently distorted colors.

It's tough to find anyone willing to repair a set that's fallen. Many circuit board tracks are very narrow and hard to repair. Then it's difficult to know if all the damage has been found and repaired, so even if the set starts working a technician doesn't know if something else won't go wrong. And then there's that bad tube possibility; no technician likes to spend lots of time fixing a broken board only to find the set then needs a new tube. Trust me, this has happened to me several times during my career in TV shops.

Your best bet is to use this as an excuse to buy a new LCD or plasma TV. 40-inch models, a good size match for a 32-inch CRT (tube) model, are reasonably priced.

Keeps turning on and off and the timer light is blinking so it doesn't even turn on fully.


Usually when I see this set with an unusual problem the first thing I do is to remove the front cover and look for coolant leaking onto the circuit board. The coolant is in a small chamber above each picture tube and sometimes the gaskets lose their seal and it begins to drip down onto the circuitry. Get a powerful light and inspect it closely for a few drips coming from the frame around the picture tubes and look for small puddles of goop on the boards. The only other common problem I run into on this set is convergence issues which usually cause a dead set or color alignment problems when set is on. I really think whoever looks will find coolant leaks. Good Luck, Russmann.

A red blue and green line jus appeared across the screen of my 55 inch rca floor model big screen. instantly my picture and color become distorted


conversions are out....rca ... check for bad connections on circuit board around fryback xformer. check fuse by flyback xformer...fuse is shaped like a little plastic rectangle>>fuses should measure a SHORT when GOOD! Flyback Transformer is large in size and sends highvoltage to 3 picture tubes via a SPLITTER . easy to locate

My bigscreen TV Mithsubishi model WS-55805 just


First thing I do on these is to disconnect power cord,pull off the front speaker grill and remove the small door covering the tubes. Get a bright light and look for coolant leaking down from the metal shields that cover the high voltage anode on the picture tubes. There is a chamber on each tube that contains ethylene glycol or antifreeze to keep the tubes from overheating. Sometimes the gaskets get a leak and coolant drips down onto the circuit board. Look very closely at the board to see if there are any drips below the tubes. If this is the case you may consider replacing the set but some can be saved by cleaning the board and sealing the leaks. Have a pro look at the tv if this doesn't help because all you can get online is a guess. Second thing that could cause this is a failure in the vertical or convergence circuit that would entail part replacement at a cost of 200-300. If you find no coolant on the circuit board that means the convergence circuit or the vertical circuit needs to be rebuilt. These sets are known for having bad capacitors on the boards that eventually have to be replaced when a failure occurs. Good luck, Russmann.

Picture tube gel leak


The best way to clean it is to remove the board completely and wipe up as much as possible, then use qtips with rubbing alcohol to remove the left over residule the alcohol will dry quickly, but still allow the board to air day a full 24 hrs before reinstalling it in the TV.

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.

Picture is Rolling..stops after some warm-up


I have seen this many times. There is a 9 volt regulator on the small signal board that causes this. The regulator goes bad and the 9 volts starts dropping, especially at start-up when the regulator is cold. If the voltage is below 8 volts then the picture gets dark and the vertical becomes unstable, with the picture squeezing down and/or rolling. As the regulator warms up the voltage starts rising back towards 9 volts and the symptoms start clearing up. There are 3 regulators in a row on the board and the regulator in the middle is always the bad one. Replacing that regulator should cure your problems but it should be replaced by someone experienced in servicing Mitsubishi projection TV's because pulling the chassis out is quite tricky.

Set will not stay on


Better get this checked out by a technican. One possible reason could be coolant from the picture tubes leaking down onto the printed circuit board causing this symptom which could end up destroying the circuit traces on that board. Other possibilities include problems in the power supply or deflection circuits. If the set is over 8 years old, I would just replace it with a HDTV.
