We have an 80's hitachi mts 52" tv/ monitor and it has a 3d effect how do we fix this?

this maybe a problem inside the layers of the screen (maybe dead pixels most likely but the layers can be replaced by steady hands or a tv repair personal)

its out of adjustment

you will have the replace the entire plasma screen. This will NOT be cost effective, will be cheaper to buy a new set vs. buying a replacement panel. Toss the set on Ebay or your local craigslist as a parts unit. If you get $60-80 for it, take the money and run !!!

This tv doesn't have 3D capabilities - the image appears blurry because both images are displayed on the same screen at the same time. Just don't use the 3D option from the BluRay player, view the movie normally - 2D.

The convergence ICs and resistors need replacement. The DPTV305-345 convergence repair kit works for most Phillips rear projection Tvs. The kit contains the two ICs 12 resistors and the CD with detailed instructions

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.

This is what the convergence PWB looks like. Its located on the extreme right side of the chassis looking in from the rear of the set.

I did the smart thing and switched over to a Sony XBR4 Bravia 52" LCD TV 1080p HD at a reduced price (Approximately $2800 from Amazon.com!). My Hitachi cost me about $ 3600 at a Circuit City Store. Therefore, no Hitachi products for me and not from Circuit City, since, Circuit City asked for $4000 for the same Sony TV, I bought from Amazon, which included delivery and installation. Circuit City would add another $80 for delivery.

Hitachi's are nothing but trouble. Take a write-off and just move on. I still have not decided what to do with my Hitachi maybe I will let Salvation Army deal with it.

You have a problem with the STK convergence modules. They're on the center circuit board attached to an aluminum heat sink that's about 8" long and 6" tall. You may be able to recreate the problem (hour glass effect) by gently moving the heat sink (which the modules are connected to). This gives the hour glass effect on the picture and the advanced convergence screen. This is an indication that the modules pins aren't solidly connected (meaning soldered) properly. Remove the circuit board and clean the old solder off & resolder the modules pins to the circuit board reconnected the board and then retest by again pushing on the heat sink. The "factory" job was good enough for 3-4 years but the heat (and these modules do create a lot of heat) and stress created from repeated use eventually takes it's toll, weakens the pin connections and our problem occurs. take the appropriate cautions working around the high voltage of the set & use a non-conducting piece of wood to push the heat sink when doing tests.
If soldering doesn't help, then the modules have died and need replacing. Don't buy the $10 cheap ones. Most of them have an upgraded version that is stronger. Also look for any burned resistors in the vicinity of the modules.
Best of luck, hope ya fix it.

This symptom indicate that your tv convergance ic faulty need to replaced ( change out all the two ic )it will solve the 3D effect problem,hope it will help.
