Yep, your problem is a relatively easy one to repair if you know how to solder. You better repair it before it blows the fuse though. There are two capacitors in the main power supply that are coming loose and need to be re soldered. There is a Toshiba service bulletin about it. They are marked C809 and C810 on the main power supply board. Good Luck

this sounds like a convergence loss... the most likely cause of this is what is known as stk's or convergenc ic(chips) have gone bad.. also it cound be the output resistors. most likely need replaced

this is a crt type tv- no lamps just crt's if it was moved recently then a seal could have been damaged on the crt cuasing coolant to leak down the neck getting into the socket. this will cause trouble for sure also could have a crack in the crt. look for a sticky liquid in the bottom of the unit.
sometime the crt's can ark and rip out a video output chip on the crt socket check it out.
not common but not unheard of.cheers

If you are capable of some basic troubleshooting you can determine what's wrong but you won't likely be able to fix it yourself. If you remove the TV's back panel, you can locate three plug connectors for the convergence correction yokes. You pull the red, blue, and green connectors and then plug the TV back in and hit the power button. If the TV comes on, its a failure of the convergence output ICs and will cost $350-450 if you call in a service company.

I have a rear projection 57" toshiba model 57HX93 that does not turn on I don't get lights or anything..What does it need?

Looks like this is reported a lot by people in various forums. Was the TV unplugged for a period of time? If so leave it plugged in for a day or two and try it again. Sounds like the whole line has a faulty power supply.

My toshiba 57 inch rear projection tv every once in awhile makes a loud pop similar to a spark noise and the screen either goes black or flickers. do you have any suggestions what is causing this??

THis could be one of the CRTs (Color Tubes) is bad or the high voltage is leaking somewhere.
Toshiba projection TVs have history of yoke problems.
My guess is one of the CRTs is arcing inside. This TV has 3 CRTs red, green and blue. Replacing a CRT is not easy or cheap to buy if you can find it. If you like this try calling a TV technician to track down the high voltage arcing. DO NOT TRY TO DO THIS BY YOURSELF.

Best of luck my friend.

I'm having a similar problem! I've taken it apart and see a spark around the green (middle) bulb. Does this mean the bulb is blown and needs to be replaced?

Look at it on the QVC channel where you have boxes with straight lines. If any of the 3 colors are bowed and 1 inch off, then it needs parts inside. If the colors are straight and only 1/4 inch off, you can adjust it. Using the remote, in the menus find convergence to adjust. Your user manual will explain it. At you can download the manual if you do not have it.
