bradhig1 Posted June 23, 2017 Share Posted June 23, 2017 Someone must havr been rough with this thing because the speaker broke from it's housing on the case. Also one screw is partially stripped and won't turn so I can't get it completely open. I tried to fine tune the rf box inside and I can't clear up the screen. The game plays just scrambled picture and no sound. Any ideas. Quote Link to comment Share on other sites More sharing options...
SignGuy81 Posted June 23, 2017 Share Posted June 23, 2017 might need to get an extractor set to get the screw out Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted June 24, 2017 Author Share Posted June 24, 2017 Don't have a drill or torque wrench to use a screw extractor. Just got a jakks activision plug and play and the screw got stripped when I tried to open the battery cover. I think whoever had it last turned it too tight when they put it in.

SignGuy81 Posted June 24, 2017 Share Posted June 24, 2017 I've had luck with this before, get some JB weld, mix it up, and put a dab of it on the end of the screwdriver(not a lot) and put the screwdriver down on the head of the screw and let it set up. Be sure not to use too much so that the JB weld doesn't also stick to the plastic so that it is touching nothing but the tip of the screwdriver and the screw. After it has set, you may be able to turn the screw out. That is another option you can try. Really need to have the thing completely apart before even trying to attempt to fix any of these problems.

SignGuy81 Posted June 24, 2017 Share Posted June 24, 2017 Once you get it all the way apart take some pics. Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted June 24, 2017 Author Share Posted June 24, 2017 I got the telstar open enough to adjust the rf and I can't clear the picture up. When I plug it in the next there is no picture just snow and I have to adjust the rf box again. The glue that held the speaker in place broke at some point and that is why the speaker came lose. When I put an Alan wrench in the hole on the right side of the rf box and turn it I can clear up the picture a little. Quote Link to comment Share on other sites More sharing options...
SignGuy81 Posted June 24, 2017 Share Posted June 24, 2017 So is it one of the screws holding the circuit board that you can't get out? Take a picture of the screw. Quote Link to comment Share on other sites More sharing options...
SignGuy81 Posted June 24, 2017 Share Posted June 24, 2017 Also take more pictures overall, and further back. Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted June 24, 2017 Author Share Posted June 24, 2017 (edited) So is it one of the screws holding the circuit board that you can't get out? Take a picture of the screw. It is one of the screws holding the case together. I took a photo of the circuit board to show the rf box that is problematic.

SignGuy81 Posted June 24, 2017 Share Posted June 24, 2017 (edited) Need better pictures. Straight on top down view of entire circuit board, both sides, and if can open RF box and get pictures. If it requires getting case apart more to get the board out and get a better picture then get that screw out and get it apart. Before doing anything else though try a different cable and see if that clears up the picture, I see it has a jack so it can easily be replaced. Pretty obvious what needs to be done with speaker, put it back secure it again and solder the leads back in place, then test to see if it works if not we can go from there, with better pictures hopefully.

SignGuy81 Posted June 24, 2017 Share Posted June 24, 2017 (edited) That screw isn't that bad, put some force down on it while trying to turn I think you can get that thing out without the screwdriver slipping. Also make sure using right screwdriver whether #1 or #2. Edited June 24, 2017 by SignGuy81 Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted June 25, 2017 Author Share Posted June 25, 2017 The picture was snowy when I turned it on today. After I tuned the rf box it got like the second photo which is where it was when I unplugged it yesterday. It keeps going back to a snowy picture until I tune it. There is a photo of the screwdriver I am using to try to undo the screw. It just won't turn no matter how much force I put on it. Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted June 25, 2017 Author Share Posted June 25, 2017 (edited) I used a bigger screwdriver and got that sucker out. I'll remove the circuit board tomorrow and look at the bottom of it. Used the same big screwdrivier to open up that jakks activision plug and play I got from Goodwill Friday. A couple of batteries in it had an accident and I had to clean it out. I am leaving it overnight to dry. Edited June 25, 2017 by bradhig1 Quote Link to comment Share on other sites More sharing options...
masschamber Posted June 25, 2017 Share Posted June 25, 2017 If I were you I'd try an av mod, if we find the chip types we can probably work out what it would take to make one Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted June 26, 2017 Author Share Posted June 26, 2017 This is how I tune the rf box it also acts as a channel select I taped the wires to the speaker and the sound worked until I put the unit back together. Tomorrow I will find a way to cut the insulation off the wires so I can solider them back on. Ebay seller didn't say the speaker fell off and the speaker wires were broken. If I push the alan wrench all they down and it touches the bottom of the shielding the graphics get garbled and when I think the picture is nearly cleared up it gets messed up when I pull the wrench out.

bradhig1 Posted June 27, 2017 Author Share Posted June 27, 2017 Soldered the wires to the speaker and now the sound works. Still can't clear up the picture. It goes from nearly clear to scrambled over time by itself. Quote Link to comment Share on other sites More sharing options...
SignGuy81 Posted June 27, 2017 Share Posted June 27, 2017 Can you get the board out and take a picture of both sides? Also can you get the RF box open(I can't tell how it is put together it may be easy may require desoldering I'll know more with better pics of the board).

bradhig1 Posted June 27, 2017 Author Share Posted June 27, 2017 Okay I got the board out and it is bent a little The RF shield has one of the battery connections on it. I am afraid there might be a wire inside running from the shield to the top of the shield. What is the blue thing that turns next to the RF shield? It changes the picture a little Quote Link to comment Share on other sites More sharing options...
SignGuy81 Posted June 28, 2017 Share Posted June 28, 2017 (edited) Thanks for the pictures. It is hard to tell by the photo for sure but it looks to me the two solder joints(ground on the RF jack the two outer pins) may need reflowing, as well as another joint looking at the back side of the board it is to the left in the picture of the other two joints I was talking about, near the corner of the RF box. It is one of the joints on the blue potentiometer. Reflow the joints on the jack and all three on the pot. EDIT: Also too looking at the back side of the board, same orientation from photo with the RF box to top. From the middle tab of on the RF box, straight down 2nd and 3rd solder joints, reflow those as well. Also the solder joint closest to the left of the RF box looking at the board the same way. Also look for any I missed that may be cracked or where you see a gap between the lead and solder, and reflow them. I say reflow but if you have the tools to desolder and then resolder them all that would be better.

If you have the tools to desolder do that first and had completely new solder Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted June 29, 2017 Author Share Posted June 29, 2017 Here is what the video looks like now. I want reliable equipment that works. This stupid Telstar, my Playstation one slim ,and that broken paddle with my ultra pong doubles why? I would like to remove the RF shield but it appears to be welded and one of the battery wires is connected to it. Quote Link to comment Share on other sites More sharing options...
SignGuy81 Posted June 29, 2017 Share Posted June 29, 2017 So is that picture after reflowing the joints? It does look improved some. Quote Link to comment Share on other sites More sharing options...
