Question about Toshiba 55H70 55" Rear Projection Television

1 Answer

Bowing image top and bottom of screem

I recently noticed the convergence was off on my Phillips rear projection Tv. When I fixed it, I noticed that there was a bowing of the image both on the top of the screen and bottom of the screen. I have heard people describe it also as "hourglass" like. My problem is minimal as I can only see slight bowing on the top of the screen and bottom and that is the only place of distortion. Can someone suggest what to do to fix this problem? Is this something fixable without repacing any parts?

Hello, I have a 60" Phillips rear projection TV


It sounds like a convergence problem; depending on your skills it may or may not be something you can do (parts cost on EBAY will be under twenty dollars).

I will attach some convergence photos: does your set look anything like these?

If it does and you can solder etc I can tell you the best place to get the parts and how to do it.

Before you rate this information let me know what you find.

It is a convergence problem, probably one of the convergence ICs has blown and must be replaced. Call the number in the last pages of your user manual to get repair service in your area.

Philips 46-inch Rear Projection with bowed image?? slight distortion



You have a convergence problem. Here are some of the most common symptoms. 

Screen looks 3D
One or more colors can't be adjusted when when using the convergence menu. 
Screen is bowed in but stationary.

Solution: 
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. Its an easy fix.

Sounds like your convergence chip has gone bad. Usually costs about $300-$400 to fix. I would call a local TV repair shop and let them give you a free estimate.
