Hello
The faut to your TV is with its vertical output section circuits. Vertcal lenearity may have changed duse to defect of some electrolytic capacitors used at that section. If you have enough knowledge in electronics and have experience ins tracing the circuit, just open your TV and locate the vertical output section. The section to your tV is built around and IC [la78041]. This IC will be screwed on to a metal heatsink to radiate heat from it while it works.
Replace the capacitors [C407, C406,C409 & C413]. Adjust the preset resistor [VR401-1], a little bit. It is the vertical position adjustment preset.
If you want to get your TVs repair details, which includes its schematic diagram, printed circuit board and component placement details, adjsutments to be done after repair etc: you have to purchase one among my Toshiba servies advertised on Fixya. I can't send any PDF files by this window. OK.

  2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
  3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
  4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand.

Hello
For what code you are asking about? Is it universal remote control setup code?

Hello
Horizontal 'Shift' is the problem to your TV. There are so many causes to this fault. Must troubleshoot from horizontal output section to video IF section. The main board has the trouble. If you can get its mainboard as card basis at your town, it will be best to replace it as card basis.
This is the picture of the main baord.

Hello
The video IF section of your TV should be troubleshooted. It is a really vey skilled work, needs through knowledge in electronics, and seperience to follow the schematic diagram of the main circuit board. Even an expereienced service technician may also take some time to detect the actual fault point.
This is the picture of the main board to your TV. If you can get it new, it will be best to replace it as card basis. OK.

Hello
It will be best for you to buy its original remote control. Universal remotes may also work with it, but some functions may not work properly. You can buy it from the Authorised Service Center for Toshiba at your town. Just give them the exact model number of you TV set [which can be noted at its back side]. They will give you the exact original one.

RCA RCR 311B model universal remote have setup codes for Toshiba. You may also try this remote. The codes are:
1047, 1071, 1103, 1105, 1108, 1159, 1163, 1178, 1188, 1190, 1191, 1196, 1211
I strongly advice you to buy its original one. OK.

Unfortunately, TVs don't always work with universal remotes. The original remote probably had a button to control the captions, and there may not be any other way to access those settings. If you can't find caption control settings using the on-screen menu, you are out of luck. The only options then are to try another brand or model of universal remote that may have a button which will work, or to locate a replacement original remote control.

Hi William,
If you have necessary tools and test instruments, and know safety precaution in basic troubleshooting, I would advice you to check/replace the electrolytic capacitor in the power supply section, this cap malfunction and produce out-of-regulation which sense by the feedback circuitry and turn the unit into subsequent shutdown. Also, look for a bad solder joints on the board., it will do the same thing. Secondary reasons of symptom is Voltage Regulator IC, and microcontroller circuitry.
If you can't do the job yourself, I would advice you to look for a technician to isolate the faulty parts.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

The set has probably blown a fuse and the power supply has developed a flaw which needs to be rectified.

Toshiba 27AF45... | Answered on Feb 04, 2011


Could be many things, have you tried headphones and have you checked the input - is it running from the antenna or from a cable box? It is unusual for audio to fail in hardware, you haven't muted it with the remote?
Finally go into the menu and reset it.

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.

Lets focus on the external portion of the TV set first (95 percent of all TV problems are related to things EXTERNAL To the tv itself) Check the physical CONNECTION of all cables by removing each wire bare or RCA and reinstalling it (Each power cable as well), once you have removed one cable, check it for fraying, and if it is already bare, splice a new fresh connection for it. 5. 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.

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.

The fact that the television stays on for hours and other times turns in five minutes shows that your problem is intermitent .A defective component in the power supply is probaly causing the B plus voltage to go up.The TV can also have a dry joint which looks more likley i am curtain if you gave the TV a firm tap to the side when it come off it would come on back. Try it .
