Question about Philips 55PW9383 55" Rear Projection Television

1 Answer

Picture issues I have an intermitten problem with my picture on my Philips 55PW9383 TV...On the top 8 to 10 inches of the screen, I have lines going straight across and at the bottom, I've got a blue streak that almost looks like a paint brush stroke. If it happens when I turn it on, I cycle power and it will go away. Any help would be appreciated!! Thanks!

It sounds like a convergence issue and possibly the amps themselves going out.. Cycling the unit off/on has me suspecting convergence amps first and possibly poor solder connections in the vert or convergence circuit. However, it could be one other thing, Vertical misadjusted. There is a methid for checking that in the service menu and I'll get to that in a second. The symptoms correcting themselves when you cycle on/off is very significant. I would first check for poor solder connections on the vert IC, and conv. amps. Then test the convergence amps themselves. If all else fails check the vertical adjustment. To adjust vertical enter service alignment mode by using 06-25-96 status, after entering service alignment mode it will be necessary to use the A/V button to get back to A/V4. When in the service alignment mode cursor down to GDE SAM. Cursor right and then cursor down to Geometry. Cursor right and then cursor down to VER. AMPL. then while watching the DVD in A/V4 cursor right or left to adjust the vertical amplitude until the white lines just disappear. Turn the set off to save the change. NOTE: Convergence may need to be touched up slightly after this adjustment has been made. Footnote: mnyce, this is one repair that I would not attempt unless you are fairly skilled at trace testing and knowing what to look for in a given circuit. As always, there are voltages in these areas that could harm you or further damage the unit. I would suggest contacting an honest qualified repair facility and explain your problem to them. Most will have no problem telling you exactly what I have here.. Goodluck. Bill

Have a model 55pw9383/17f that had convergence issues for a while. The reds, blues and greens were all seperated. Now I turn it on and have no picture.

Your convergence has failed and needs to be repaired.You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

Visual transparent lines at top of picture

You have a vertical output circuit problem. This was common for Philips' sets. Have a repair shop check it out. Should not be too expensive to repair.

32Inch Flat Screen SDTV - with picture distortion

If you have a TV shop at all any more in your area, any tech working on them will know where to look. This is a pretty common problem although you are getting it too early.
Since it will require a certain type of instrument (capacitance meter) to verify the problem part, I don't want to go into detail concerning a 'do-it-yourself' repair since it may be a little difficult to order these in single quantities and a decent shop should have the right value on hand.

It shouldn't cost too much.
