Question about Philips 7P4830W 48 in. Rear Projection Television

1 Answer

Convergence Problem My Philips/Magnavox 7P4830W 48" rear projection TV (1997) suddenly seems to have a convergence issue. When on the convergence menu the red line is displaced to the right and will not move when I try to use the remotes buttons. I have read other posts which suggest the STK ICs are bad; but it appears that those are for some other model or manufacturer. I opened the back and on the left side is mounted the GR7D DGITAL CONVERGENCE BOARD. I removed it and located IC13 Convergence Spline Processor, Philips CSP613178-1/9705RVA69 after I removed the top and bottom heat sink covers. Might this part be bad and if so where can I get a replacement and how would I solder this as it looks quite complicated?

My phillips 51'' rear projection tv has red and green shadows on it

The convergence is off on the tv more than likely. Check the owners manual on how to adjust convergence or call the manufacturer they are good about walking their customers through the steps to fix convergence. You can also press the menu button or try another source such as a dvd player and/or a gaming system. If other sources have the same issue it's for sure the tv.
