Question about Toshiba 46H84 46" Rear Projection HDTV-Ready Television
The TV will turn on and the sound works but the screen won't turn on at all. From what I can tell the tubes aren't glowing at all. The screen doesn't appear to be getting any power. Is it a problem with the hv splitter or possibly the deflection board and if so could you define what part? I might try replacing the deflection board. Is this the right part? http://jr.partsearch.com/Part/Toshiba/Toshiba/46H84/Toshiba/Toshiba/23762135/New.aspx Thanks

If you have zagged lines there are 10 small surface mounted capacitors you will need to change on the HYper Board. This is not an easy repair so alot of folks simply replace the hyper board. You will need a service manual to take this set apart and to get the proper part number. If you have no TV repair experience or do not know how to solder, as the hyper board has sheild arounfd it, you should play it safe and call out a pro to assist you in this repair. Good Luck

sammy jo ,you burnt the tubes by leaving it on with a vertical collaspe faultmnow you have three damaged tubes,i also think that you also have a bad yoke which is taking out the new parts ,the cost is within reason,the shop repair is to insprct it deeped for possible other faults and damage already done.

have you checked your fuse? Will the relay click when you press power? You may possibly have a bad relay or the bridge rectifier diodes could be open.

The deflectionmodule will be almost impossible to get. However it sounds like you quite possibly only need a flyback 259296 and the HV splitter which are the two most common items to fail. you can get both parts at the following link along with free online tech support so you can repair your set yourself, or they can rebuild your Circuit board. Leave them a email include the model number and what you need.
