If Magic focus will not correct it (it is the limited auto convergence for this set) both the convergence chips which should be stk392-110 or 150 will have to be replaced, convergence is done with the original remote with set in the Decam ( tech convergence mode).The parts are not that expensive and TVrpairparts.com sells kits with instructions for these sets by model number.

this set has no reset button at all. If the screen is flashing is it red,green, blue, 3d or what? This may be a clue to what is wrong.

Do you mean only the screen goes off and sound remains or does the tv go off altogether? Also what is the status of the LED at the front when it goes off?

hi this is a problem with the main board clearly

the fact that it is not allowing a code and also the fact that it is asking for a code that was never put in on the first place this shows that the main board has a fault and is causing the controll unit to send out a locked message that cant be unlocked it is not possible

solution:new main board

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Check the CRT board on the back of your Red CRT Tube check to see if the driver chip is bad. Most likely you will need to have a tech replace your red CRT.

behind the speaker grill
open up the access panel
look for the focus block - it has 6 knobs, labeled very small and hard to read, r, g, b - focus and screen
-dont move screens unless you need to change the drive of the crts.

there is also a wingnut (mechanical) focus knob on each lens, dont move unless electrical focus doesnt work

Hello jcklbmartin,

This sound like your shutdown circuit is being activated. This can be caused by the drawing of excessive current from one of the other stages of the TV, or by the failure of one of the capacitors connected to the IHVT. In any event I would suggest getting the TV checked by a qualified TV technician.

I hope this helps

Thank you,

Did you try to physically unplug the TV? Leave it unplugged for a few minutes then plug it back in.

Hi,
What is model of your TV, question shows its Hitachi 51S500 rear projection, please confirm.
Thanks.

In most cases the convergence IC's will need to be replaced and the alignment touched up. This is not really a labor intensive repair for a technician to perform at all. I would say see if you can get an estimate for a minimal amount or free if the shop does so then make your decisions from there. Mind you to look at the cost to replace the TV and the fact that TV's today will run more efficiently on electricity. Please take a moment to rate my answer. Thanks....

See if on the back of the TV, and on the computer you have an external type VGA type connector. You then have to purchase a long VGA interface cable to go between the laptop and the TV set.
The TV must be compatible to receive the VGA and external audio from your computer, and the computer must be capable to drive external audio/video devices.
Another issue that must be worked out is both the TV and computer must have compatible screen resolution rates. You will have to get the information about the display card in the computer, and compare it to the specs of the TV set. If these do not match up in to proper range you will either have a very stretched or compressed picture, or you may not be able to have any results at all.
If the scan rates are too far out, it is possible to damage the TV set!

If everything is technically correct, you will also have to purchase compatible cables to go from the lap top external audio output to the correlated audio input connectors on the TV. This is an adapter type audio cable.
For these cables, you will have to determine the connector end types on each of the units, so that you can go to any audio/video supply store and properly pick them out.
There is a simpler solution, but it will not have good picture quality. You can buy a VGA to baseband video converter box (if these are still available). These are not cheap but they can work if set up properly and the scan rates can be matched. You attach the converter box to the external VGA port on the computer, and then use its output via the proper baseband video cables to drive the TV set. The scan rates will still have to match. The quality will be very poor.
