TV picture shaking!!!

Is it 7 years old? Marvelous. Exciting. the lifetime of Maxent televisions are 6 moths the most!!!
You're lucky.

DLP projection tvs are bulky and have a design flaw in the convergence board the 2 STK convergence ICS alway dies constinely require replacement,if u use about 4 or 5 hours day in and day out.If the old Mitsubishi tv several years since is was repair,u use it alot?If yes,it time to retire it,and buy the refurbish Plama tv.Not,than get the old tv repair.U Know how to solders?Tries Websites Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.U can go to You Tube type in Convergence problems will see a tutoring video in repairing 2 STK Convergence ICS.

That sounds like the convergence problem I had about a year ago, and like you, I replaced the convergence chips and that fixed the problem. It's cheaper to replace the chips if you do it yourself, but maybe not if you send it out for repair. If you can find an exact replacement board, that would fix it too, but I wouldn't necessarily expect it to last longer. The advice I read on replacing the convergence chips in my rear projection TV was that they would last 2 or 3 years and then need replacing again. So you're within that range.

You are describing 2 different problems. The convergence problem can be fixed by either resoldering the convergence ICs or replacing them. These ICs cost about $25 each and there are 2. I suspect that the $4oo is for replacing the convergence board. This should not be necessary as the board can be fixed. Also, the brightness problem can be dirty CRTs, dirty mirror or faulty coolant fluid on the CRTs. If the picture was good prior to the convergence problem, the set is probably worth the repair if you can get the board fixed. While the board is being repaired, the service shop should be able to tell whether or not the brightness can be adjusted.

Is the power indicator flashing three times? If so the Ics have shorted shutting the set down. You will need two STK392-110 convergence ICs. You can get replacement ICs at the following link with free installation instructions.

Convergence problem needs two ic 's to fix.

this indications that you have a problem with convergence. first try to go into customer menu...setup....convergence. and see if the convergence will adjust.. if it wont then you have a problem with the convergence cuircit boards.

Your Projo is a complicated piece of equipment, involving 3 picture tubes (like 3 tv's), convergence failures are extremely common, I dont think $550 is totally unreasonable, but I dont think it is a power supply issue if it is just effecting 1 color, usually it would cost around $100 parts $300 labor to repair, might be a little high, I suppose they are also charging you for pickup and delivery, I hate taking sets into office as that sometimes jars stuff loose or cracks boards.

It sounds like the Hyper board is begining to fail....Does the menu shake too?

this is caused by a bad convergence module, and there are probably some dried out electrolytic caps in the circuit as well. i have one in the shop right now that came in with the same problem. if you have it serviced, make sure they replace all of the convergence modules (there are usually 2, but sometimes 3 of them), because if one went bad the other(s) is likely to go out soon as well.
