Re: Pioneer 510-HD

EchoKaos may not have resoldered his PS board, which most units in that line need. This will most likely solve the problem. A virtually complete resolder is needed on that board, not just the obviously problem areas.

If not -

If the hor lines are upward and curved slightly and a couple of inches apart, then the blue Screen trimpot on the focus block is most likely turned up too high. When turned down the lines will disappear.

This mucks with your grayscale, but then it's trashed anyway by now, and after reducing it, you will have to do a new grayscale on your set, or have one done by ISF. Or a tech who knows how to set the Screen controls, since ISF does not teach that.

How do i get rid of purple horizontal distortion lines?

This is a older model and likely the first generation of HD set made by Mitsubishi---where the HD input is on rear (DTV?) ARE THERE TWO JACKS MARKED H sync and V sync?

If they are there set needed an external box made only by Mitsubishi for for later HD use.

Tv screen shuts off, light blue comes on and horizontal bars cross the screen. the sides have orange and blue vertical lines and middle shinks in. If i turn off the main power, wait a few minutes...

I agree that it is the power supply board. I had a problem with my Phillips 42 in. HDTV. It would not turn on at all.

I opened it up and found several bad capacitors. I removed the bad ones and replaced them with good ones and its up and running.

My suggestion is to inspect the capacitors on the Power Supply Board. Look for bulged leaking or misshaped capacitors. If you find any replace them or have them replaced. They are very inexpensive.
Or just replace the whole board

Hope that helps

1. My Sony KP-57WS500 TV is turning blue after abut 3 minutesof operation. It stays that way for about 30 miunes and comes back with pictures again, but with predominatly blue color. 2. Sometimes the TV...

Sounds like the picture tubes are failing,common on sony. do you notice any thin horizontal lines? You mite get lucky and be able to adjust the voltages. Remove back cover and look inside to see which tubes are lighting up.The front panel below the screen will come off and behind it is a small access cover.remove it. there you will find the voltage controls (its a plastic square with 6 knobs). 2 knobs for each tube, 1 is focus the other is the voltage labeled "screen". they are marked so look closely. Green is always in the middle but sometimes they flip the controls for red and blue so pay attention to which you are controlling .slowly adjust screen voltages to see if you can get it to stay on. If you over do it those thin horizontal lines will pop up and the tv will shut off again. If you already have lines back off the voltage by turning knob to the left slowly until they diappear. If that seems to fix it but the problem but it comes back later, then the tubes are shot. good luck!

My Sony KP-53S35 turns on, shows a blue screen, turns off

It sounds like the blue CRT (picture tube) is failing. The part number for this is 8-733-575-25 but you will need a technician to replace it for you as there is mechanical and electrical alignment to with with it. At that point it probably isn't cost effective to repair the TV. Please take a few moments to rate my answer. Thank you.

WS-55515 Loss of sound and HD blue screen

First check set for problems by:This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. Self-diagnosis error 2-3 indicating deflection failure. Check for shorted or leaky Q5A37 part # 260P818050 located on PCB-Main. If found defective replace only the transistor instead of the Main PCB.

Right side convergence

A convergence IC has burned out. If I remember correctly, those Pioneer sets have one huge convergence IC, but that IC only has 5 channels in it so they use another smaller dual STK IC and one half of it is used for the 6th channel and the other half is the vertical output. Look on the convergence board, find the blue convergence jack, identify the blue horizontal channel, follow the traces and replace the IC handling the blue horizontal channel.

Screen and volume problem

Hello, the problem regarding horizontal blue line can be around vertical output stage with IC(LA78045). Please check for cold soldering, resolder the suspected solderings. Best regards.
