Sony kp-53s65 no pic has sounds


Trace the voltage to the main board and you must be able to confirm that the +B to the board is in order. since there is sound the front end sections are in order and the fault relates to a failed drive or video process.
Check the power to the lamp circuits if there is no output this is the area to trace.
if there is glow on the screen then there is absence of video output drive and it needs a trace. use of signal tracing and injection might be needed or you must get help to confirm before any board or costly spare is changed.

The 3 colors are not ligned up and the picture is out of focus. We tried the flash focus and that did not work. we tried the convergence but are unsure on how to use it.


Colors misaligned in rear projection tv due to failure of convergence output ICs and replacement of bad ICs will solve your problem, it needs soldering work in tv circuit board with proper tools, if you are handy with electronics stuff repair ad can replace parts in circuit board then let me know to provide you more info OR contact local tv repair shop to get tv fix.
Thanks.

There is no picture when I turn the TV on, the red lamp light under the power button is blinking, when you turn the tv on, it goes off for 60 seconds, there is a ringing buzz every 20 seconds, then the tv...


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is xl-2100 you can find it here: http://www.discount-merchant.com/Sony-XL-2100U-TV-Lamp-p/sony_xl-2100u_replacement_lamp.htm?Click-48173.Have a blessed one!

Tv will not turn on. light flashes green for 20 seconds then turns red


Sony made great tv`s but they have their problems too. What happens while the l.e.d flashes is that the main processor is waiting for the o.k from various circuit in the set before it turns everything on, so the problem could be from any critical circuit in the set. you`ll need the help of a experienced sony repairman. good luck

Hitachi projection tv, 50ux26b, picture jumps after it has been turned on ~20 seconds, then it settles down and works fine. advice?


The two most common problems with Hitachi projectors are in the verticle sweep circuits or the convergence. Both can cause that symptom. The good news is it is likely to be bad connections on the convergence power pacs or the verticle output IC or both. If bad connections are observed it is a good idea to resolder all suspected bad connections in general. There is a remote chance that the problem is out of tolerance filters on either the main sweep board, or a problem on the PIP module circuits. Consult with a repair specialist if you need more information.

Below is exploded view of your Sony KP-51HW40 TV rear side which shows board names and location.
You need to check D Board for convergence ICs and these are marked as IC8001 & IC8002 on circuit board.

Projection TV keeps shutting down


I just took my Mitsubishi WS-65315 65" in to be repaired for the same problem and was told that it needed a new main circuit board part number 930b899005 as was told they wanted to charge me $1100.00. So I told them not to do the repair and picked up my tv and found that same part at Sears parts for only $225.00. Some of these TV repair places are theifs.

You can download a PDF from here: http://www.servicemanuals.net/results.aspx?type=SM&brand=0&model=50EX20B Make sure that the coolant is not leaking out onto the printed circuit boards. i have had the remote sensor cause this problem before and also I have had bad capacitors in the sweep and the main power supplies. Good Luck
