Question about Toshiba TP50H60 50" Rear Projection Television

1 Answer

Toshiba tp50h60 convergence

My TV would not power on. I changed out the convergence IC's. Now TV turns on, but convergence is out of alignment. I went to fix it in the menu and I don''t have any of the cross hairs show up. Everything else in the menu appears, the Red and Blue color options, and the screen with 1-9 showing. But no cross hairs to line up

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.

When I turn on my toshiba tp4880a tv it turns off immediately and then I have to unplug and plug it back in several times to get it to power on


You are probably experiencing primary stages of a convergence IC failure. This repair is composed of replacing two output IC's and alignment. Standard repair is around $350

50H13 Red Convergence Problem


Yes, it could be from the convergence amp having a loose connection. Big Screen tv's have problems with loose connection especially when moved or bumped. If you can take back off and find convergence amps then safely tap on ic's and see if it changes picture then it's maybe just aloose conn. If no change then you need to check resistors inline to red. At the most replace IC's these are the large STK's by a heatsink. Hope this helps!

1998 TOSHIBA TP50H60 THE COLOR WON'T MATCH, LOOKS LIKE 3-D MOVIE WITHOUT THE GLASSES. IF YOU HIT THE SIDE OF TV, SOMETIMES GOES BACK TO NORMAL.


Sounds like a classic convergence problem. most likely bad connections on the bottom of the stk's. If a repairman were to do this for you it would run $300-$500, if you were to do it yourself it would run less than $100. Bad connection on the vertical IC can cause something simular to this as well. If you need more help or would like to fix it on your own please let me know
