Re: my projection tv sony 51 inch red out of focus

Your convergence output IC's have either shorted out or opened up, either way they will have to be replaced and possibly a resistor or two. One distant possiblity is the DCU or the Convergence Yoke, but most likely the IC's. You will probably want a tv repairman to do the repair as there is some soldering to do and some paste/ IC's to install/ calibrate. A repair like this could run from $300 - $500 for IC's depending on who does the repair, The Yoke or DCU would cost a couple hundred more.

My TV looks like it had permanent 3-D. Red Ghost

hello it sound like the convergance ic may be the problem these chips sit behind the tuner board connected to a metal frame called a heat sink they are soldered in. also you will have to check the resistor in front of the chips also check the 2 capacitors at either end it would be best to get a quote from and engineer good luck

Screen turns red then shuts off

Sounds like a bad red projection tube, disconnect red tube socket and try again if tv stays on reconnect tube soket and adjust screen controls on front of tv under the front panel which you will have to remove to do any of this. There are six adjustment controls 3 are for focus for each color and 3 screen controls for each color. Look close at the black plastic control module should be labled R G B for focus and R G B for screens. Good Luck!

I have a sony 50 in rear projection. 9 years old

Sounds like the CRT tubes are going out which is fairly common on Sony. Inside the back of the TV there are 6 knobs - 2 for each is for focus - dont touch - the other for brightness...turn down the brightness just a hair untill the lines go away.

Half of the screen is clear and left side of the screen is blury

Its a Common Problem with Projection Tv's ~ If your flash focus is not correcting the problem, And It can Not be Adjusted in your service menu: under Manual Convergence, your IC chips and maybe a few resistoirs may have failed and need to be replaced!... onegeo

Faint red curved lines on Sony KP 51ws500.Converged = no work???

Hi There!
This sounds like a typical problem related to a older CRT.
If you remove the front cover of the tv, you can then remove a wood panel. Behind this panel you will see a block (high voltage splitter) it will have 6 "knobs" on it, 3 will say focus, 3 will say screen.
They will also be labeled R - G - B  
Put the tv on a blank input so you can see the lines clearly on a black screen  - Find the knob for red, and SLIGHTLY turn it down until the red lines disappear.

My screen is blured (focus problems)

This sounds like one of your convergence IC's has burned out. There are 2 IC's in the set and the one that handles RH (Red Horizontal) has stopped working. The IC should be replaced and the set realigned by someone with experience.
