Question about Hitachi 51F510 51" Rear Projection HDTV-Ready Television

1 Answer

Black screen I turned on my tv today and the screen is black with rolling red and/or blue lines. If it is a picture tube are those typically expensive as this tv is almost 5 years old and I am wondering if I should buy a new one or have this one repaired? Thank you.

Turn your screen drive down to green and blue tube.
You have a focus/screen drive control block that you can adjust each tube R/G/B

Screen fades from normal at start-up to blue in about 10 seconds, TV stays on, display goes black, sound still on, and red light on front blinks 5 times

These sets kp51ws500 had issues with bad picture tubes----this set uses a Red,Green and blue picture tube.

The tubes are only available on a rebuild basis and very expensive. There is one thing that requires no parts replaced you can try: here are the instructions:

v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} SONY WITH BLUE SCREEN PROBLEM:

You may have a bad blue picture tube but there is a way to deal with this first----the set has a black plastic block with six controls---three are Focus(red,green,blue) the other 3 controls are Screen controls(red, green, blue) Someone has to remove the entire piece on the front of the set below the screen(usually a plastic part) most of the time it is secured with 3 screws on either side of the set in the back; once you remove the screws the entire piece should pull out(pull from right to left(it will not fall off or come out easy--it is held in with several large plastic pegs) With it removed there is an inspection plate with 4 screws-----the screen/focus block is behind it.

You need to look very closely at the block to identify the focus versus screen controls----one row left to right will be marked Focus and the other row left to right will be marked screen------YOU need to locate the Blue Screen control(they are black like the block) With the set on(be careful) go to a video input clip_image001.gif with nothing connected---if you see a blue screen as well as the input number turn the BLUE SCREEN CONTROL SLOWLY TO THE LEFT UNTIL THE BLUE is gone.

If this cures the problem you may only be buying yourself some time----if the blue picture tube is bad sooner or later this trouble may return----I have seen sets where this was adjusted and the set worked for a year or more with no repeat of the trouble----replacing the blue tube would likely cost you 400 - 500 parts and labor.

I do this here for free so if this has helped you take a moment and give me a vote here.

Red lines on Sony KP51HW40 Rear projection TV

Yeah, seen that more times than I shoulda in the last 4 years. The red picture tube has a cathode to heater short. That means it's no good. That red picture tube is no longer availible. But all is not lost. There is a company that rebuilds those tubes reasonably. Most reputable tv shops will know this. The ones I've done cost around $450 out the door. One minor hitch is that with all the shipping involved the job usually takes about three weeks. That can be expidited but then the price goes up.

Screen fades to blue.

The Blue SCREEN setting is too high. These adjustments are located inside the TV behind the front panel. There are two screws behind covers and then a wooden panel to remove to access the adjustments. The leftmost set are for BLUE, the middle are GREEN, and the right are RED. The top row are FOCUS and the bottom are SCREEN. Focus will focus/unfocus the tube and Screen will adjust the power of that tube (there are 3 tubes, one for each color). If Screen is adjusted too high, horizontal lines will appear (my TV had red lines, but I played around with the knobs and saw that it could happen on any of the colors). Additionally, if SCREEN is set even higher than that, the tube could go so high that it turns the whole screen that color (in your case, blue). If this happens the TV will shut down, probably due to either overheating or overvolting. To fix this issue, turn the appropriate SCREEN dial down until the lines go away. In your case, you want to turn the lower left dial down. Don't turn it too far down, if you turn it more than necessary the TV can give you an AKB error (noted by the STANDBY light flashing a sequence of 5 blinks).
