Question about Toshiba 55H70 55" Rear Projection Television

Problem with repair man

I called a Toshiba certified repair man over 2 months ago, when he came he took the board from the TV to fix the convergence, he came back 3 weeks later and it got worse. The convergence was worse and the picture kept spinning. So the next day he took the whole TV and now has had it for 5 weeks. He told me it would be made a priority fix, but every week he has excuses for not fixing it. Two weeks ago he told me he fixed it, and then this Tusday he said he was doing one more thing, and after that I left a message everyday for him and no one picks up or returns my calls. I went to his shop Friday afternoon, though their timing is 9-5, no one is there, I had went there on Wednesday also and the guy there told me he would tell the boss to call me, but that never happened. This business is also not a member of BBB, what steps can I take? Thank you.

Call toshiba and ask them if they can recommend another toshiba authorized servicer have them put your tv back together and tell them its an excessive time to wait it ten words or less they dont know what they are doing 90 percent of the toshs fixed should be completed in two hours or less

Heckler, your tv has blown parts in the convergence circuit so you need to stop pulling plugs or you will do more damage to the set. The convergence IC`s will need to be replaced and probably 1 or 2 support resistors, Then the set will have to be re-converged, the shop you talked to is correct that it`s a common problem, mine failed 8 months ago in my 53" Hitachi. $400 to do that repair is pretty pricey BUT it really depends on where you live, Major sized city`s charge big rent, taxes are higher etc. etc. so tv shops overhead is higher, I would get out the phone book and start calling all the shops in your area for price quotes. Any questions??? email me back, hope this helped, Happy Holidays BMW Rider

Toshiba TP48C90 Convergence (replaced ICs, worked for 2 days)

Well, my thought is that there are a ton of knock off generic convergence IC's out there that usually hold up as long as yours did. Professionals like me will only use Sanyo original STK's. The counterfeit STK's out there are everywhere. Do some research on the web to locate Sanyo originals, they are out there.

Convergence amp

You usually have to replace the two ICs at the same time along with resistors to get the longest life from the Convergence amps. You can get the repair kit for your model at the following link which contains both ICs and all 6 resistors plus instructions with pictures that explain how to do the repair yourself. Heres a link to the correct kit for your model Toshiba.

Convergence problem ,Help Please

Something is not right here. Is there any possibility that you can get the circuit designation (Rxxx) of the resistors that were "incorrect"? I am not aware of anything like this that can cause the "memory to be erased". The only memory in that area would be the factory convergence settings which can be modified from the service menu. Please try to supply the resistor IDs and I'll check on this.

Tv comes on but has no picture or sound

There is a board on the right side of the tv called the convergence bd

There are little connectors that are on the left of the board
the last one is the power to the convergence Ic's

That is the one that is closest to you. they are little black conectors with wires in them

Carefully lift it up

Then plug the tv back in and see if it fires up

If it does do not run it long

just enogh to see the tubes light
then shut if off

If it goes on

your convergence ic's are Shorted

They have a kit for this tv it is available through local parts distributors
If you can't find it locally just Google HITACHI CONVERGENCE KIT

If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit

If you are not sure about doing this repair you should have your local tv guy do it for you

If it does not go on then I would suspect the regulator in the power supply But
Most of the time it's the ics

Very wavy picture- gets worse when show has fast-cuts

First thing Do not beleive peeps about a bad card. Modules are not used in TV sets any more unles your talking about a complete board change out for a Zenith TV set. Toshiba sets do not have a card or board changeout!.. These peeps are crooks! A Toshiba set is repaired to componet level. It sounds like you may have a convergence problem or a problem inj the power supply involving the filter or couping capacitors. Seek out a pro whos an authorized servicer for Toshiba.
