Question about Toshiba 53H71 53 in. Rear Projection Television

1 Answer

Touch focus error will not correct

We just recently purchased 2 things, 1) brandnew stereo speakers that sit right next to the TV. 2) Wii console, in which the TV has been moved away from the wall a few times. We get bad shadowing with red and blue outlines, almost double vision-like. Can we fix this problem or do we have to call in a service? My husband is pretty handy and could probably fix it if explained how to. We get touch focus error everytime I try to use this feature. Thank you, Debbie

If the touch focus isnt working and the picture has a 3D look you will need to change the conversion ICs. This is a straight forward repair just unsolder the old and solder in the new. You will need to replace both. They are located on a large aluminum heatsink and they will have STK numbers stamped on them they are quite large easy to find. The numbers will be something like STK392-110 or simallar. Let me know if you need anymore info.

    you can get the Convergence ICs at www.electronix.com you will have to look inside your set and see what the numbers on your ICs is. then just order 2 of those ICs. They are easy to find, they are located to a huge aluminum heat sink. And if you would like the service manual for your model for your set let me know and I will post a link.

Helping me to get my Wii talking with this 480 resolution sceen


The wii will run on almost all televisions. As long as you have the correct components (R/G/B) or purchase an accessory to hook up the console to a different input, you will be able to use it on your TV.

We have a projection Toshiba Tv that we bought in 2004 and lately every time you turn on the tv there are lines going through it and you have to hit the touch focus button every time in order for the


Touch focus adjusts at a limited number of places the convergence--next time it does this go into menu with the remote and look for CONVERGENCE in the menu, you will be able to call up a grid of lines or crosses--point here is to see if red or blue are out of position, if so with the remote adjust there and see if it stays when next turned on.

I tell most people with this brand NOT to use the touch focus--it tends to misadjust things and does not SAVE the adjustments it makes---the ones in the customer and hidden tech menu will be saved.

Checking to see if a convergence problem and if so adjusting manually is the first step---may solve your problem and do not keep using the touch focus----its a joke in the repair industry.

When the TV is on, on the outlines of people and text are in Red and Green lines. I have tried the touch focus and it is not working. it is saying that there is a "touch focus error" can I manually adjust...


you need 2 new convergence chips, part number stk 392-110, also check for burnt up resistors next to the chips, major disassembly and soldering, you probably need a tv repairman.

Red horizontal curvy lines


You need to turn the voltage on the red tube down slightly, also you would need to adjust focus to compensate for the lower voltage to the red tube. On the left and right bottom side of speaker cover are two round covers, take them out and there are 2 1/4" hex screws take them out carefully take cover off, there is another service cover same hex screws remove. You will see the focus block on the right side, tubes are labled on block. 2 knobs for each tube. Make voltage adjustments while tv is on a black screen, then for focus, turn color all the way off in the menu, and adjust focus until it looks right in black and white. These adjustments should only be very small; if alot of adjustment is needed, you may have other issues.

Sony kp-53HS10 blinks 5 times then picture goes off, sound ok.


Pull off the front speaker grill after removing 2 screws on the bottom corners. The grill will come out from the bottom before it can come down, then it is off. Undo the wires ties by hand to get 1 foot slack in the cables. Remove the 4 screws on the 1' by 2' hardboard cover to get into the bottom of the TV. Find the 6 adjustment pots (2 rows of 3 pots) One row is the "focus", do not touch these. The other row sais "screens". These you need to adjust. Turn on the tv. Use the tv/video button to switch to a black screen. You need to go up and down to get "cut off" to black for each gun/crt. Turn each screen controal clockwise untill you see color, then counterclockwise slowly and stop when that color goes black. Do this for all 3 screens = all 3 guns/crts =red, green, blue. If this Sony adjustment does not fix it, than you may need a new gun/crt which is expencive.

No Picture from Component Input #1 or #2 but do have audio via Surrond Sound


Simplest thing would be that your component cables are not HU'd correctly. Having them reversed would do this.

If you have the ability to work on solid state electronics and know how these circuits work, you will need to replace the convergence IC's in this TV set. If you do not, call in a pro to assist you in this repair. Good Luck
