I have decided to chane the ballast on my Toshiba 62hmx84. Before I attempt this does anyone know if there is any soldering involved? Also is there a website that I can get a step by step process of changing the ballast with pictures or schematics? I am a little nervous about doing this, but I know if I call a service guy and watch him do this I'll end up saying, I could of done that! Here we go!!!!!!!!!

Re: changing lamp ballast
Email me privately and I'll be glad to send you the service manual - just make sure to include the model number and what it is you need. I get more than 3000 emails a day and they're very hard to keep straight.
The real question to ponder about calling the "service guy" is when he's done with the job he's likely to go home unharmed. Whereas you touch the wrong thing at the wrong time in that HV circuit and you're not likely to come home again. Us "service guys" not only spent years of education learing electronics 101 we have ongoing training seminars, conventions and manufacturer class instruction to keep up on the latest technology. I'd strongly recommend you have the tech do this one and live to say "I could have done that." Besides the damage you could do if you cross wire the ballast.

I have a 62HM84 Toshiba TV. I lost picture on my TV in the past i have bought the lamps and i just put it on and the picture comes on. This time when i replaced the lamp nothing happens no picture. It tries 8 times to turn on, but nothing happens. Can you help me with is what is the problem.
What is the model number??, There are just way too may Toshiba sets to try and guess the one you have!! or try here. http://tacpservice.toshiba.com/ConsumerProductSupport/Manuals/TVom.asp Good Luck TECHMAN.
I do not think failing to reset the Lamp Timer would cause the Lamp not to light. You need to get into the Factory Menu while the picture is on in order reset the Timer. I believe you have a Ballast issue either because the Power Supply is not powering the Ballast or the Ballast not Powering the Lamp. In either case, the only way to know is to have a professional to check it out and give a estimate for repair.
I hope this helps,
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.
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.
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.
