TV picture shaking!!!

My TV is going on 7 years old. No problems other than a convergence problem 3 years ago that was fixed. Now I have a picture shaking issue going on. The convergence seems fine and needs adjusting every few weeks with the weather. The picture shakes when first turned on then seems to settle for awhile. Thanks for any suggestions or help. my tvs picture shakes and after warm up used to only be up at the top . now its all down the screen. please tell me a way to fix this or a way to check myself. i dont have much money and want to repair this myself

    For the first 15-20 seconds after the tv is on, there is just wavy lines. Over the next few minutes, the picture gets better but the wavy lines never go away. The tv is only 7 years old. What's the deal?

You have a Hyper module problem.Very common with these chassis.Toshiba part # 23148024.This part is no longer available,but it can be repaired.I dont know how much electronics training you may have but it`s a pretty detailed job.The hyper board is the silver stand up module inside the unit right behind the external Audio/Video jack panel.There are 11 little capacitors that all need to be replaced.The value of these caps are 10uf @ 16VDC.I do this job for about $245.00 and the unit works fine.Check with your local shop if it is too much for you.If you don`t know what you are doing you can ruin this module then it`s time for a new set.Good luck.

The left side of the picture has red and green stripes and ghost images. The right side does not have this problem, but the picture is not quite right. The convergence chips were replaced two years ago and...


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.

Hi I have a toshiba 50h82 tv that is 7 years old with a convergence problem with the red and green lines that is going to cost $400 to fix but now that I am thinking about it before the convergence problem...


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.

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.

Power supply/convergence issue...


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.

Wavy picture


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.
