53h71 convergence probs

Hi Guys,
I am trying to help someone fix their toshiba. I was a factory tech for years& was spoiled by all the new parts,schematics & comparison sets.field failures are kind of out of my area.It is collapsed.
The problem is the green net at the bottom left. it will adjust horizontally but no vertical adjustment. It seems to work everywhere else. my guesses were the to try to change the digital convergence board & then possibly the vertical convergence amp.I was just able to look at it for a while with no equipment, didn't notice any burned components. I hate to waste this guys money guessing. Any help or ideas will be greatly appreciated.

    I was waiting around to see if there were any more suggestions. It makes sense that something that gets that hot would fail first. Maybe everyone else agrees with you. I haven't tried the amp yet , if so i would have given the highest rating. Thank you for your input. If it fixes it i will let you guys know.

    Thanks again!

I was told by repair shop that the hyper module on my Toshiba 53H71 has gone bad, and they were not available for unit to be repaired . Any help ?

there are a few shops that can physically repair these. I have personally repair a few. but is very very tricky... it requires some very trick soldering to some very small was replaceing so many of these they gave instruction on fixing these. it involves replacing 11 very small micro capacitors.... like i said very labor intensive. my shop generally charge 250 for the repair. just depend on who you get. WARNING this is the kind of repair that the technician can easly do more damage than good so get a respectable experince tech to facilate this repair

Panasonic PT-47WX42 blue horizontal convergence failed

Picture you submitted with this is Toshiba--if set is Panasonic pt47wx42 it uses two STK-392-110 CONVERGENCE IC'S----both need to be replaced and any of the blue 2.2 ohm resistors around them that are bad changed also--the resistors are light blue in color--if you locate them look for any that are white in the middle. The convergence chips are on metal heat sinks next to each other and are black(about 2 inch wide and 1 1/2 inch tall). They will have the STK-392-110 number printed on them in white.

You can buy both chips on Ebay for less than 20 dollars including shipping. I have step by step instructions for this repair on this kind of set--if you have the skill you can do it yourself.

Most of these sets just need the two chips changed and the set adjusted. If you cannot do the repair yourself--now is the slow time of year for TV shops--shop around--I do this kind of repair in the home--takes about an hour--shops will try to charge 300-400 for this and I do it for 200-250----I have done hundreds of these sets in the last year.

If someone wants to "take it to shop" keep looking; any good tech can fix this in your home; once the chips are replaced they will be good for about 5 years--some go 8 years.

If you want the instructions let me know and give me an email address and I will send them to you---If you have the skill you can do it yourself--
You did not ask---the reason they fail is there is a white heat sink grease applied to each of them when they are installed--it transfers heat from the chip to the metal quickly--after several years it dries out from the heat and the chip reaches a point where it cannot move the heat fast enough--it then fails.

I do this here for free and if this has been helpful give me a vote here--IF you have any questions or want to have the instructions reply to this here--The instructions are my own--they are in Microsoft word.

Regards, SD TECH

Yes, the convergence IC's need to be replaced. If you are not experienced in TV repair, I would recommend getting a qualified repair man to do it for you.
