Question about Televison & Video

1 Answer

After replacing hv splitter and focus block and about four hours of adjusting the convergence board in the front I finally got a great picture, but now i notice when you have a title like on my dtv receiver stating what is on tv or something like that it is blurry from time to time (more often than not) and also the bottom if something flashes across the screen, but the main screen itself looks great most of the time. I didn't have this problem before the splitter and focus block went out.

Is this set a RCA ? You may want to double check the seating of the Anode Lead from the HV Transformer to the HV Slitter, If pulled out
a little arching will occur with-in the Bock and cause premature failure if not corrected. Also make sure that all ground connctions are made from the CRTS to the HV Block if there are any.
Hope this Helps,

GREEN CRT OUT OF FOCUS


The individual lens have a lug nut that when loosened allows the lens to be turned-----cover red and blue lens and call up the convergence grid---from the rear adjust that lens until the green lines are in good focus(can also do the red in and the blue if needed)


You will get no more advantage as the manual focus controls on the splitter block have very limited range.


when done carefully tighten the wing nuts on the lens back tight.

Have a Sony KP-65WV600, already replaced d board once, and replaced convergence ic's once also. Now as soon as I turn unit on, turns to red screen and shuts off, video that is, audio works ok, noticed...


Check High voltage Block.After replacing ic's (STK convergence ic's) you need to adjust Black&White scale.Turn ALL screen adjustments to min.Turn TV on and adjust screen slowly for each gun (I would start with Red first ) when you came to point that you see red background with white lines across, at that point G2 is too high (that will cause TV to shut down,don't worry just lowered adjustment and turn tv back on) so adjust to proper voltage and do the same for each gun.After that, adjust focus for each gun (again all controls are on High Voltage Block and HVB is mounted on front of your tv after you take speaker gril out) black box with 6 controls' screen RGB, focus RGB .
You should do that in dark room in order to get perfect Black&White scale,when all guns are adjusted properly you will see grey picture.Make sure 'Color" adjustment on your display is down to 0. Another step is convergence adjustment ,Flash Focus etc.If TV stil shuts off after all, your Red picture tube is short inside,take crt pcb from tube,make sure TV is unpluged from power before that, and turn Tv on .If stays On tube need replacment...good luck)

The large red wire gets pushed in then turned about 90Degrees and it pops right out of the HV splitter. The smaller red wire gets traced back up front and unplugged from the focus block behind the speaker grille.

Mitsubishi Convergence issue


If the screen is out of focus you probably need to adjust the focus on the focus block it is usually located behind the front grill, there are 6 adjustment screws on this block, leave the screen controls along just adjust the red, green, and blue focus screws. When converging a set everything is converged to the green, the blue and red are suppose to come to the green.

Pincusion/Convergence Problem


You can find some presets on the display section of the motherboard. You try adjust to fine tune the picture.

Keep a mirror in front of the TV and try adjust the presets slowly with the help of a properly insulated screw driver.

Caution TV venerates very high voltages.

Have a Sony KP-51WS510 with red outlines


In replacing the CRTs, there are multiple focus adjustments. The basic one first is the Mechanical lens adjustment on the CRTs, (in this case red), the second one is the Electronic Focus on the Screen/Focus Block on the front of the unit behind the front panel. The third focus and on of the most important is the Beam Centering Focus. (In this case RED CTR) It is located on the neck of the CRTs. They are the first set of adjustment rings up from the CRT Boards. If any of these focus adjustments are off they will cause a symptom like yours to occur. Normally these adjustments are made before any convergence adjustments are made. I would double check to see if the repairman made these adjustments.
I hope this helps

TV will not turn on


Probably needs a new HV Splitter block, they are very difficult to replace and can usually be accessed thru the front behind the speaker grill and behind convergence board.
