Question about Toshiba 57H81 57" Rear Projection Television

1 Answer

Main board price and part number

I need the entire main board replaced/rebuilt/refurbished for my TV (it's the whole board that sits on the floor of the inside cabinet). Repairman is quoting me about $815. Would like to know if that's a fair price, and also if there is somewhere I can buy one of these myself and put it in maybe for less. What part number am i looking for? Thanks!

Looking to find out what is the difference between the BN94-04251A and BN94-04251X

The difference between the letters means Aftermarket or refurbished. To be sure, ask Samsung. Usually the X means refurbished. Usually both numbers will work.

I need to replace the HDMI input terminal on my PT-43LC14 Panasonic multimedia projection TV. I need the part and instructions on how to install it.

On most televisions you can not just replace the HDMI input terminal you will have to replace the entire video/audio input board assembly. I have tried to look up the board but this part is part of the Main Tuner unit and is only avaiable if you replace the entire main Tuner/CBA.

Have a Pioneer pro elite 730hdi. When you try to turn it on (main power, not standby), the tv cycles from the red (standby) light with the normal click to the green light, then one second later, it cycles...


Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like, to buy a whole refurbish power supply board for the replacement.

Hoping this will help in solving the problem....

I have a blinking red light when I go to turn the tv on, no picture no sound

Glad I found you. I started to answer your question when the power went out here. Ok, for starters the first thing to repair is the convergence board, How do we know it is bad? Pull the back cover off. You will find two boards on the floor of this TV.In between these boards you will find jumper connections that connect these boards. Find the location number 1516 (next to the jumper cable). TV is unplugged of course, disconnect this jumper. Now power up your TV (plug it in the wall), and turn it on. The picture and sound will come back. The picture will be bent and curved as well. Unplug your TV. The board you will remove will have all the RCA jacks and RF connections.The large board on the floor is called the signal module. You will have to replace the convergence ICs. They will be the STK 392-110 ( two of these) and mounted on a couple of large heat sinks. You will replace these ICs and some 1 or 2 watt low ohm resistors. You may call Union Electronics and purchase a refurbished board with core exchange, if you feel you cannot repair on a component level. This number is 1 800 648 6657. Price may be $192, plus shipping and exchange may be $50.This is a smart move as the replacement board will have a warranty. The second idea, if you feel you can do a component repair, is to contact the website This web site is very complete and has photos with all instructions and parts. Price here may be $79. Thanks for asking and show all hands of support!

Main board is shot.

This will have its own main board, easily replaced, what you need to do is take the board out and get the part number of it then Google it or Ebay for a replacement.
Hope this helps
