Question about Toshiba 62HMX84 62" Rear Projection HDTV

1 Answer

Lamp ballust I'm thinking of attempting to replace the ballust on my Toshiba 62hmx84. I've replaced the lamp, but I'm still not getting a picture. So what I'm finding out is that the next thing to go to is the ballust. Ive been quoted $300.00 from a repairman to replace, but the part is only $48.00 from partstore.com. I've never worked on a TV before, but I have fair to mediocre mechanic skills. Is this something I should replace myself or should I pay the $300.00.

    I am trying to help my parents fix their t.v. and this problem, apparently seems to have happened for more than a few people. I have only recently found out my parents have been getting the run around from partstore.com about replacing this ballast. They live here in portland and this is my first attempt at helping them fix the problem. Could you please email at G.cavett@yahoo.com, My name is Garrett, and from what I gather, taking it somewhere is the solution to this? Any information would be greatly appreciated.
    Thank you '

The $300.00 is a more than fair price... Some shops charge as much as $450.00 and you don't want the junk parts that partstore.com sells. Probably wouldn't last ten minutes in your unit... Use genuine Toshiba authorized parts and you'll be much happier with the results.. The ballast is Toshiba p/n# 23122468 and costs about that much plus shipping from a reputable parts distributor - but the quality is assured. Secondly, if the ballast isn't all of the problem and you blow a new ballast the tech can have it exchanged without cost - you do it you'll just have to buy another one... And finally, the shop has more equipment to work on that unit that I'm fairly sure you don't have like a variac. After installing the ballast it's a very smart idea to power the unit for the first time on the variac at a lower voltage and monitor the ac line. If anything goes wrong the tech can simply chop the power or drop lower to avoid damaging the light engine or something more critical or expensive.
I've spend twenty years in electronic repair as a licensed shop and it's my STRONG recommendation that you have the shop do this one.

SOURCE: replacing lamp ballust

You should definately go with the repairman - You have now replaced the lamp, if you replace the ballast and that doesn't cure the problem you'll be that much more into the do-it-yourself repair and still you'll end-up calling out the tech.. Besides that who makes good on the warranty if you don't get the polarity correct and short something really expensive like the light engine?? Don't get me wrong I'm a real fan of trying to save people money - just look-up my history of solutions... However, ballast replacement in this unit is not as fundamental as you might think.

Picture loss after picture begins to flash. blue and yellow light


Most likely the lamp is dying. Try replacing the lamp before calling a repair tech. What does the Owners manual say about the blink lights?

Not the lamp!


If the lamp did not cure your problem you have a defective optical block. This includes the ballust for the lamp. On Toshiba sets the the ballust comes with the optical block and connot be purchased seperately. Prices vary acroos the country and from shp to shop but you are likely going to spend about $800 to repair this.
