I had a similar problem with my 42 in Philips LCD HDTV. Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired ofcourse) and found four bulged capacitors on the PSB. Many major electronics companiesPhilips/Magnavox, Sony, Panasonic, and others were sold capacitors that failedin 2-5 years instead of 10-20. Thecapacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in allsorts of devices and cause a wide range of failure problems. Here are some options for you. 1. Have it fixed by a professional $$$$$$$??????? (Is itunder warranty?) Remember, TVs CONTAINHIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk. 2. Open your TV and find PSB. (The board that the power cordplugs into) Check for faulty caps. If you find some (bulged or leaking) bad capsreplace the entire board. The entireboard costs around $250 right now because they are in high demand right now.They can be found at tv-part.com but supplies are limited. I would definitely shop around though. 3. Remove and then replace individual faulty caps. This takes some soldering skill. Caps are inexpensive and if you can take care of it yourselfit will save you hundreds. This may be your problem. If you determine that it might be. I have a Tip/How TO tutorialon this site that may also help. Itgives step by step instructions for replacing caps on PSB #715t2432-2. If this isyour board you are in luck. Here is theLink: Fixingthe Philips Turns/shuts off on its own problem. I'm working on uploading pictures to helpguide people though the process as well. Let me know if I can do anything to help. Hope this helps and if it does please rate itaccordingly. Good luck.Kaufman605

I have a 48" sony projection with a rainbow comming down from the top


You have convergence circuit failure. Convergence IC's have to be replaced and probably some PICO fuses that soldered on the same board. This repair require good soldering skills.

Green projection light not alligning with red and blue. Flash focus will not bring them back. Sony Rear Projection KP-48S70


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!
See link for more detail

Note:The convergence/defletion/power board (the one the IC's are on) of this model is on the left hand side (when facing the back of set) also check for blown pico fuses when replacing the convergence IC's The best way to replace the IC's resistors and possibly fuses is to remove the entire board.

My sony KP-48S70 is stuck in standby. How do I get this turned off?


Usually the tv is in standby because of a failure. Does the red light blink when you try to power it on and if it does, how many times?

How do I perform a convergence adjustment on a Sony kp48s70 rear projection tv?


Hi, you picked a real difficult set to do, you`ll need the service manual,the original SONY remote, you may need to change out the ic`s and a few support parts, ie; resistors & chemical fuses which you can get at acme enterprises in orlando, be sure to read the entire convergence section of the service manual before you change any settings, my advice is to pass but gl if you go for it, video-tek
