20 Most Recent Mitsubishi VS-45607 45" Rear Projection Television - Page 7 Questions & Answers

I am Not sure what it is you are needing code to Mitsubishi TV ? Codes for remote unit 0093-0150-0178-1250 these are the codes i have for one 4 all remote.

Caps in the vertical circuit are causing this and taking it to a reputable shop won't be all that expensive... The tech will ESR (equivilent series resistance) test the caps and replace those with a high ESR or open which should solve the problem..

I would suspect bad solder connections on the convergence IC's caused one to short out a blow one or more pico fuses, thus causing the set to go into shutdown so as to stop further damage to the set. The TV will need to be seen by a profesional to confirm or deny this.

This symptom seems to be a vertical Sweep fault cause what happens is theres a protection circuit in this set that activates when it sees theres no verticle sweep, it shuts off the picture on the set so that the tubes dont get lines burnt in the middle and become damaged. If you know your way around a TV set then you could locate the vertical output IC and resolder all its pins first as well as anything else in that circuit that looks like a cold solder connection. Then i9f it still does the same thing I would just replace the verticle output IC as well as the B+ supply capacitor off the flyback xformer for the sweep dirived power supply. Now if your not knowlegeable about these HI VOLTAGE circuits my advice would be do not attempt the repair yourself as you could get hurt and /or cause more problems with the set as there are no tubes in this set to test except the picture tubes. Contact Mits. at this #800-332-2119 or look in your owners manual for a contact #. Good Luck.

The vertical yoke plugs have DY stamped on the board next too the wire plug.Its located on the main PCB on the far right side looking in the rear of the set. Arcing in the CRT can be many different things such as a defective HV lead to the CRT or even a bad ground on the CRT drive Circuit board which is attached to the bottom of each CRT.

okay a 12 means no error was detected so I would look at the boards for any signs of CRT coolant leaking onto the chassis as thats a real possibility with that model. Look for any signs of a pasty residue on the boards under the three CRTs.

This doesent sound like a bulb problem to me at all! it sounds like a few capaciters need replaced! Look put the screwdriver down and call a pro because you could ruin the set trying to do a minor fix and causing a major problem!

To unlock, using the Original remote, press 9 and QV (QuickView).
Then go to the main menu and select channel lock and turn that off. When it asks for a password, press 9 and QV again.

Good Day;

This common for this TV; CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB.

Good Luck, big IRISH.

Press QV and 9 on Mits remote.................................T.

Good Day; Just replace the caps first, 99.9% fix if not replace 9v regulator. Good Luck, big IRISH.

I have a VS-45607 and If the VS-5052 has the same menus then there are two options for convergence. One is the basic convergence where there is one set of crosshairs and you line them up. Then there should be an option for "advanced" calibration where the whole screen looks like a grid and you go to un-converged crosshairs and align the screen. Most likely not all of them will need to be adjusted, but for me, the lower right hand corner wasn't aligned right and this cleared it right up.Good luck

For my VS-45607 I had to first take off the speaker grill. Then there is a panel just below the screen that can be removed with screws; I removed this just for wire clearance. Then there are a few screws that are along the bottom of the screen that you take off and you should be able to slide the screen up and off. Good luck.

Your problem is capacitors CP204 and CP205 by the 9 volt regulator on the main board. Cp204 is a 47 microfard @ 50 volt and the other is 100 microfard@ 16 volts

there should be metal brackets that hold the screen in all the way around the frame. there are usually 2 screws to each bracket..you have to remove all of them to get the screen off

Try Re-soldering the vertical yoke connections and vertical output IC. This is quite common with this model.

On CRT projectors, there is a part called a focus block with adjustments for each picture tube. A sudden loss of focus is pointing to something else, a change in the high voltage. Poor high voltage regulation will cause a loss of focus. If your loss of focus has been gradual, you can try adjusting the controls on the focus block. The focus block is usually a square or rectangular block, usually mounted on the front behind a panel or on the rear behind a panel. it will have a series of red wires coming out of it. There usually are 6 adjustments on the block, 3 for screen voltages and 3 for focus. Be sure you adjusting the right ones, they are usually labeled.

MOST TV'S MANUFACTORS HAVE A MASTER RESET-- I SUGGEST GOING ON LINE TO MITSUBISHI AND DO THE " CONTACT US" THING---MAY POST A PHONE # FOR CUSTOMER SERVICE--TUNICA

YOU HAVE THE DREEDED CAPACITORS GOING OUT...AFTER A FEW YEARS-THE CAPS LOOSE THERE PURPOSE AND DEPENDING ON WHAT CIRCUIT THERE IN --YOU WILL SEE THE ASSOCIATED PROBLEM,,,EXAMPLE--COULD BE SOUND ,PICTURE (YOURS) OR VERTICAL(PICTURE CLOSING UP) ETC... YOU CAN HAVE CHECKED BY A REPAIRMAN BUUUUT ,MAY NOT BE COST EFFECTIVE ,,TUNICA

CLEANING THE " LENS" MIGHT BE POSSIBLE IF YOU HAVE A LITTLLE SKILL,,UNPLUG THE TV FROM THE WALL OUTLET ,,,,LET ME REPEAT THAT --UNPLUG THE TV FROM THE ELECTRICITY....TAKE THE BACK OFF THE TV---LOOK UP AND YOU WILL SEE 3 PICTURE TUBES POINTING UP,,,ON TOP OF THE TUBES THERE IS A LENS (GLASS)...YOU CAN SPRAY GLASS CLEANER ON RAG OR PAPER TOWELL AND GENTLY RUB OFF ALL THE DUST AND DIRT--USUALLY REALLY BAD IF SMOKERS-- WHEN U GET THRU ,,PUT THE BACK AND REPLUG IN WALL OUTLET--THERE IS ALSO A MIRROR ON PROJECTION TV'S --I RECOMMEND A TECH FOR THAT SERVICING --IF YOU ARE UNCOMFORTABLE ABOUT DOING THIS ----DON'T

THE FRONT SCREENS USUALLY AND RARELY NEED CLEANING...JUST USE A SOFT CLOTH AND RUB TOP TO BOTTOM ON THE OUTSIDE ONLY-GEENTLY TUNICA
