Question about Toshiba 62HMX84 62" Rear Projection HDTV
I'm thinking of attempting to replace the ballust on my Toshiba 62hmx84. I've replaced the lamp but I'm still not geting a picture. From what I'm finding out the next thing to go to is the ballust. I've been quoted $300.00 to replace from a repairman, but the part is only $48.00 at partstore.com. So I'm think of replacing it myself. I've never worked on a TV before, but I have fair to mediocre mechanic skills. Is this something I should try or should I go with the repairman?
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.

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.
