This problem stems from defective surface mount capacitors on the "hyper module" (which is no longer available as a part). The capacitors can be replaced by a technican with good soldering skills however and is accompolished by using 105 degree type PC style or 10 uF/16 volt SMD caps. All 11 of them must be changed for a lasting repair. They are at locations: CX 178,221,230,241,250,261,270,514,541,670 and C5030.

First - Please rate this solution using the rating option below.

If it looks zig zag looking and its moving around ( not fixed into place)...your hypermodule has likely failed. You can get parts and instructions to repair this from www.TvRepairKits.com

CERTIFIED TV EXPERT HERE, follow this information I provided 3 long solutions to this issue/s Solution 1 Before we start taking things apart, lets try your simple remove power plug routine and power system back up. Also, please try your unit on a few different channels to see if your problem continues on each channel. Your Main Board, Power Board, T-Control Board are suspected problems at this time. Press and hold the power button for about 15 seconds, the unit should power down by itself after you have powered it on. If it does not, then do not be concerned. Let me know if the problem continues. The first link below will bring you directly to the troubleshooting guide if you need to continue forward with the same error.

Check to make sure there are NO OTHER uneeded radios, system nearby. these systems, when powered on, will cause electromagnetic interference and prevent more than just severe tv interference SURGE PROTECTOR Surge protectors account for more than 75 percent of electric faults to stereo equipment. Lets start with your AC Wall outlet. It is standard in america that 220 Volts from out of these outlets. This implies that each device will be using 220 Volts (From within that grid zone). If anything including an alarm clock is plugged into any AC outlet socket in the vicinity of the stereo equipment/TV, it will cause electric outage, and prevent electronics from even turning on! Your TV needs dedicated electric power. If your TV is located in the living room then unplug everything else in the living room. Lets plug the TV set into a Dedicated socket. Check all light switches to ensure that power is on for that outlet. Check the TV cable for Fraying both on the ac wall end and where it plugs into the TV. Check all GFCI outlets to ensure that all red reset buttons are pushed in, check the circuit breakers for proper connection and they are turned on. Now, lets try the TV set without it connected to any cable services, vcr, dvd, stereo system, etc. Please respond if we have found a solution. 3 When troubleshooting these units, there are always several variables to consider. First check to see what last occurred with the unit such as did the children play video games, did the electricity go out due to bad weather. You may see that there are many possibilities but let's focus on what occurred last to the unit. Once we determine what happened last, we may isolate the actual cause of the problem. The actual cause may be associated with projection issues, older versions (Picture tube), interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common with the error you have provided today. Please continue to look for anything EXTERNAL to the unit before looking at the internal components. I have been working on these a long time so feel free to follow up with me

Please check the molel number. It must be 40UX600U. The UL605U is a different series altogether and I am afraid there is no upgrade currently available that will allow you to watch films via netfilx.

If you mean it will no longer store the settings, replace the X2402 8 pin EEporm. They are only a few pennies to buy and that will save you a fortune.

Hello davema....replace the STK chips and make sure resistors are ok, If the board is different i wouldn't use it.
(Please click on high lighted words)
Hello, friend you have a convergence issue, first see if they will move manually in your menu, they should be able to move up down left and right, and if not this is when two chips labeled STK392-xxx Failed. They can be located by finding the largest heat sinks in the unit.
Along with the possibility being an open resistor and or open fuse in the convergence circuit. All of the resistors around these chips should be checked pay attention to the ones that are standing up and they all should read low ohms, If they are in the k ohms they are probably open which is bad ,This is a tricky repair, if you have Never done this repair I don't suggest it.
But if you are willing to tackle this problem the only step by step procedure I found for you would be to watch someone do the repair, and this I found on the internet in the convergence problem screen. This will give you an idea of the work involved and also what the parts look like. For sites were you can pull up manuals, check here

As with all products that contain a digital display, in rare instances, when viewing certain content (e.g.. television broadcasts, video games, DVD), you may notice that the sound and picture are slightly out of sync. This phenomenon can be caused by various factors including, without limitation, video processing within the TV, video processing in an attached gaming system, and video processing/different compression rates used by broadcasters in their programming. You may want to try one or more of the following suggestions, which may help to reduce the effect of this phenomenon:
  • If the TV is connected to an external A/V device (e.g., DVD player, video game system, set-top-box, etc.) always try to use the Color Stream video jacks and corresponding audio jacks or the HDMI input (if available on your TV) for connection to such external A/V device.

  • If the TV is connected to an A/V receiver that has a programmable audio delay feature, use this feature to help synchronize the sound to the picture.

  • If connected to a video game system and your TV has the Game Mode feature (see owner's manual for more information), enable this feature.

  • If you notice this phenomenon only on certain TV channels, please contact your local broadcast, cable, or satellite provider to inform them of this issue.

Sound like you have the microcap problem. This a common problem with these sets we see a few in the shop every month. First i am sorry to say this is not a recomended self repair. even tech have trouble with this one. THe problem lies on a cuircit board called they hypermodule. there are 11 tiny micro caps that are bad. toshiba has issued a service bulliteen to shops on the problem and what we do is replace these very tiny capacitors. which invovle twezzers and a magnifier. Ideally the best solution would be replace the whole board but these are difficult to find. and replaceing these caps are diffucult i have personally damaged two board getting these caps off. and like i said hard to find board. at our shop we charge about 359 to repair so this set is repairble.

CAN YOU SEE THE MENU FROM THE TV. MAYBE CHECK ALL THE CONNECTIONS FROM CABLE BOX OR WHATEVER THE SOURCE IS. IF IT ISN'T SOMETHING SIMPLE LIKE THAT THEN I SUGGEST CALLING A SERVICE TECHNICIAN YOU MAY HAVE A VERTICAL FAILURE OR SOMETHING WRONG IN THE VIDEO PROCESSING CIRCUITRY.

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 of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. 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 yourself it will save you hundreds.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide 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 it accordingly. Good luck.
