Part of my Television screen is blacked out on the right side. It started with 5 inches and now it is about a foot.


It sounds to me like you shorted out some of those ribbon cables. This is easily tested by going into the pattern mode on the tv. It will put patterns on the screen. If the screen is still black during the patterns, then you have indeed shorted out the panel. It's cheaper to buy a new tv than a panel. Follow these directions to enter into the patterns. I really hope it's not the panel.

I have a Sportsart 1050l give's error 1?

ERR1 Definition: The display board CPU didn't receive the optic sensor signal. • Explanation: After processing by the drive board, the optic sensor signal travels the 16-pin cable to the display board CPU, which determines motor speed. Components involved include the optic sensor, optic sensor wheel, 16-pin cable, drive board, display board, and connections.

ERR1 Condition: Press speed key; walk belt doesn't move; ERR1 appears. 1. Drive Board a) Inspect drive board components for signs of damage, like bulging, burnt or cracked spots. b) Inspect connections to the drive board, including the ribbon cable (at the display and drive boards), drive motor, incline motor, etc. loose connections are a common cause of ERR1. c) Check the drive board lED Turn on the unit. The should be lit. The EMG indicator should light up and then extinguish after the unit powers up. A lingering EMG light indicates drive circuit trouble, but it can also light up if drive board connections to motors and other components aren't secure. d) Test whether the drive board is sending power to the motor. Put the muttimeter to the DC setting. Disconnect the motor M+M- wires from the drive board. Place probes on the drive board M+ M- terminals. Put the treadmill safety key in place; turn on the power; walk on the treadmill so that the ClK lED lights (this preempts the display from detecting no optic sensor signaling and immediately giving you an ERR1 message, thus allowing you to get a power reading); press the speed up key. The meter should show some voltage. If there's no voltage, inspect the ribbon cable and display board. If they appear OK, suspect the drive board. e) Test drive board components for a short. See Components in the Basic Electronics. 2. Ribbon Cable a) Check the ribbon cable and its connections. Link a spare cable from the drive board to the display board, outside the unit. Test the unit. If it works with the spare cable, replace the original cable. b) Or, if you don't have a spare ribbon cable, test ribbon cable continuity. Wrap solder wire around each probe so you can insert probes into the ribbon cable connector, testing one wire at a time for continuity. 3. Display Board a) Press down on the display board ICs. If you have a working unit of the same kind, swap the display board onto this unit. Test. If all works well and no ERR message appears, replace the original display board. a) Reed Switch (Applies to models with magnetic safety keys only.) Put the safety key in place over the reed switch. Put the meter to the 200 Ohm setting. Place probes on both ends of the reed switch. Meter should show 0 Ohm. If the meter doesn't get a reading, replace the reed switch. 4. Treadmill Motor a) Rotate the motor. It should rotate smoothly. Grinding or sticking indicates wear. b) Check the motor brushes. Uneven wear indicates worn brushes. Minimum brush length: 1/2 inch. Turn the brushes around and reinsert them. Rotate the flywheel. If the motor grinds or sticks, put brushes back in their original position. c) Check motor resistance: Turn off unit. Disconnect the motor M+ M- cables from the drive board. Put multimeter setting to Ohms. Place probes into the motor wire M+ M- ends. Normal reading: 1 Ohm. Move the flywheel slightly and take another reading. Take a few readings, moving the flywheel slightly after each. Readings should be consistent. If the meter shows OL at any test point, replace the motor. 5. Transformer a) Put the meter to the AC setting. Place the meter probes on the transformer output wire connectors on the drive board. Turn on the unit. There should be output voltage. If not, replace the transformer. • 11XX/12XX brown-brown: 10.5VAC • 31 XXl32XXl61 XXl62XX white-white: 12.5 VAC • 6005 yellow-yellow: 11.0 VAC If ERR1 is not resolved, see ERR1 with walk belt movement. • • • • ERR1 Condition: Press speed key; walk belt moves; ERR1 appears. 1. Tachometer Wheel Make sure the tachometer wheel: a) Rotates in the middle of the optic sensor. b) Is clean and free of cobwebs and dust. c) Doesn't have broken or bent teeth. d) Is fastened securely on the motor bracket If the wheel has visible damage, replace it. 2. Optic Sensor Make sure that the optic sensor signal is getting to the drive board. a) With power on, turn the drive motor. The CLK indicator (an lED on the drive board) should light. This means that the optic sensor signal is reaching the drive board. If the ClK indicator doesn't light, replace the optic sensor. b) Push the treadmill belt while pushing speed up key. If ERR1 doesn't appear until you stop pushing the belt, and the display speed values increase, then the optic sensor is good. (On units without a ClK indicator, check optic sensor output voltage: (a) put probes on optic sensor output (b) turn the motor (c) if voltage doesn't vary, replace the optic sensor.) 3. Ribbon Cable a) Check the ribbon cable and its connections. Link a spare cable from the drive board to the display board, outside the unit. Test the unit. If it works with the spare cable, replace the original cable. b) Or, if you don't have a spare ribbon cable, test ribbon cable continuity. Wrap solder wire around each probe so you can insert probes into the ribbon cable connector, testing one wire at a time for continuity. 4. Drive Board Check whether drive board components are burnt or cracked. Check component connections. A drive board power component short usually results in a huge burst of power, making the walk belt speed dangerously, before ERR1 appears. If the walk belt moves before ERR1 appears, but not very, very fast, suspect the optic sensor. 5. Treadmill Motor a) Rotate the motor. It should rotate smoothly. Grinding or sticking indicates wear. b) Check motor resistance. Turn off unit. Disconnect the motor M+ M- cables from the drive board. Put multimeter setting to Ohms. Place probes into the motor cable M+ M- ends. Normal reading: 1-2 Ohm. If there's no reading (OL), replace the motor. c) Check the motor brushes. Uneven wear indicates worn brushes. Minimum brush length: 1/2 inch. Turn brushes around and reinsert them; rotate the flywheel by hand. If it rotates worse than before, put brushes back in their original position. d) High amp draw can indicate a bad motor. Other factors would be a worn walk belt and deck. Run unit power through a current meter. Tum on the unit. Normal amp draw at 3 MPH with no load on the walk belt is 1/2 to 1 Amp. 6. Display Board ICs Make sure that IC contacts on the display board are good. Press firmly on the ICs. Make sure you have the latest CPU version. If ERR1 is not resolved, see ERR1 no walk belt movement.

Red light blinks an odd pattern


Thats most likely a error code. But I will need the model number of the set and the exact number of blinks such as 1 blink then 6 fast etc. Also does it repeat the sequence ?

The sound loads, but no picture at all. I have an original 1981 cocktail Galaga game.


HI Kristen,

IF you can "play" the game blind, that shows the game board is working fine.
The issue can be in the monitor. That can be many reasons there is no picture .Check all plugs and connectors. Make sure the back of the CT is plugged in. Power to the monitor is present. Do you have amanual for the arcade? You should be able to find one online.

Do you see the picture tube lit up, not on the screen, but in the back of the neck of the tube? (Orange glow from the filament)

I"d suggest that you seek out a qualified service person for the game, if you are not familiar with working on electronics.

There are fuses in the cabinet power supply I believe, check those. Could be something as simple as the fuse going to the monitor.

Nice machine, hope you get it going.

Upright Ms. Pacman video game has really small screen?


if you're good at soldering, you can replace a few things on the monitor's main board. puffy capacitors (look like cans) especially. but before you do so, you'll need to discharge the crt tube by running the stored charge (up to 20,000 volts dc) straight to a ground source. it's a big deal and it's dangerous if done incorrectly, so you might want to leave it to the professionals. now might be a good time to change to a lcd monitor.

Ms pacman from free play to pay play


You'll need to open the cabinet and locate the game board to make this change (be sure to turn the machine off first, and it's a good idea to use some sort of anti static device on yourself before handling game boards). Inspect the game board and you should notice a bank of tiny switches (these are called dip switches). If your game is in Free Play mode, switches #1 and #2 are both "On". Here's how you can change it:

Switch 1 Switch 2 Mode
------------ ------------- ----------
Off On 1 Coin - 1 Play
On Off 1 Coin - 2 Plays
Off Off 2 Coins - 1 Play
On On Free Play

I hope this helps!

My MsPacman/Galaga upright has power but screen is black(blank)


I'm assuming this game cabinet was built in the 80's. More than likely, the monitor is an Electrohome GO-7. If this is the case, replace capacitor C511 on the monitor board. It has baked open due to old age. Usually, capacitor kits can be purchased for around 10 bucks, so you might want to replace all the caps on the board at ths time. Worst case scenario would be that the Flyback transformer has smoked (usually you'll see a crack on the side of the transformer), causing the horizontal output transistor to cook and also the smaller of the two pigtail fuses to blow. In this case, you would have to replace the Flyback transformer, the horizontal output transistor, and the small pigtail fuse associated with it. Remember to always discharge the second anode( the suction cup thingy on the side of the tube). It will hold a substantial charge on it. Also, if the small pigtail fuse is blown, you will need to discharge the large cap on the monitor board, or else it will knock you on your rear-end when you try to replace the blown fuse. Hopefully, you'll will only have to replace one cap. C511. If your game does not have an electrohome monitor, I can still help, if you provide the manufacturers info, such as Well Gardner model 7204, or something like that. Good luck!
