Sony WEGA Casing Repair
I have a Sony Wega 36FS100 and I have a 0.5"x0.5" puncture in the right
speaker casing. Really the only issue here is an eyesore, it looks like the plastic was cracked and pushed in. Question is, has anyone gotten to the point where they can remove this speaker grill from the tv unit itself, how much is involved. Its just out of warrantee so i would rather not take it to sony depot, but I just need to remove the casing off the TV to be able to access it from the back and push it back and glue it or something. Anyone have experience in taking one of these suckers apart? Alex |

Sony WEGA Casing Repair
Over an email, it is hard to do an accurate evaluation from your
description. If you are not used to TV service, I would not suggest this. You will have to remove the chassis assembly, and there are a lot of connectors, harnesses and etc that will have to be disconnected, and re-connected. There are also some safety issues with this venture. There is also the chance you may accidentally disturb something, and if so, the repair will be much more costly than having a service tech who is used to doing this type of work to do it for you. This may only cost an hour of labour to fix. There is also the possibility, you may need a new part. In this case, one will have to be ordered from Sony. -- Jerry G. ===== "Alex" wrote in message ...

It may require removal of the crt also, not a do-it-yourself project.

Alex,
provided you are carefull should be no reason why you cannot try to fix this safely yourself. Assumming that you can't pull the bamaged plastic out with a paper clip we can talk you through it. Best put the unit face down (don't scratch the glass). You'll need to remove the back casing. unplug it and wait a while for all the big capacitors to discharge. Undo all the screws and gently lift the back casing straight up. Be carefull of a) they put a sticky tape around one edge that may cause the casing to jeck off suddenly b) the power cord will get in your way. Be very careful not to bump the inside of the tube. Some basic precautions (sorry if you are and experienced techie). - stay away from the fat red wire (high redisidual charge) - make sure that nothing can knock the end of the tube or the attached board (risk of tube breakage) - make sure that nothing can knock the yoke (coils) around the tube (critical picture alignment) - don't knock any of the small magnets on the back of the tube - dont touch any of the boards if you can help it (electrostaic damge risk to boards, plus shock risk if you touch the power supply caps (big fat ones). hopefully they discharged by now, but you never know. The speakers are on either side of the tube and simply unscrew and can be lifted out. Absolutely no need to remove the tube or anything complicated as has been suggested by other posters. Putting the back casing on requires careful attention and you will need to be carefull that you don't drop it on anything. The bottom board will need to be moved around until the back casing slides on easily. The Power cable has a small plastic lug that has to slot into place before the case will close. Good luck!!
