Question about Toshiba 61H70 61" Rear Projection Television

1 Answer

I have a toshiba 61h70. the tv had been shutting down after and few minutes and the red bulb was flashing also. I replaced the IC Chips and it resolved the flashing and shutting down issue. the green and blue bulbs converge but the red is off still. is there something else i need to do or replace? also it converges down the middle of the screen but the four corners and sides are not aligning.

You need to look with a meter at the resistors around the chips, they are usually gray in color with bands that denote value--a good guess is one or more were taken out by the chips--in these sets they will look fine---typical is 1.8 ohm (brown, gray, black bands).

At least one is open (bad--no reading across--like checking a fuse) and there will be several with identical color bands on them.

Let me know if I can help.

Bulb goes out after a few minutes


The ballast for the bulb is the culprit. That is the circuit board directly wired to the bulb. You can get a replacement on line at:

Older-model Toshiba TV shuts off by itself


There is a large sand filled resistor on the main board close to where the power cord attaches that cracks. This will stop power until it cools enough to make the connection then heats up rapidly to open it again. It may be worth the trouble if you're handy with a soldering gun and can get the back off the TV. If not then I'd consider getting a flat screen.

Yes, its a convergence problem and you may be able to fix this yourself if you have a soldering station and a few basic tools. Its possible that all that is necessary is to re-solder the pin connections on the convergence output ICs on the underside of the cicuit board. There may also be a poor solder connection on a jumper wire connection near the ICs. Its near the plastic frame. If this does not resolve the issue, you will need to replace the ICs. Remember to unplug the TV before doing any service.

Toshiba 61H70 Weird Convergence Issue?


They may have gotten some cheap convergence ICs, thats a real possibility. I would recommend switching the two origional STK392-110 with some STK392-150 they will run alot cooler and last alot longer. Just use a good coating of heat sink compound on the back of the ICs. I will post a link where you can get top quality Convergence ICs and they provide free instalation instructions with pictures so you can do the job yourself in under an hour and save quite a bit of money. Heres the link.

According to the E44W48LCD service manual, the temperature indicator red light states the projection TV shut down due to overheating. Red (flashing) states the projection TV shut down, check the cooling fan.

TP50G60 bad scrambled picture - shuts off after 1 minute


This does not sound to me like a convergence roblem. It could be a shorted picture tube. That would put the set in a shutdown condition. Normally in Toshibas , the picture remains on with a convergence problem. Here is something you can try, but you must be very careful. Remove one crt board at a time from all three tubes. if the set stays on after one of the crt board are removed , then that is the shorted picture tube.I cannot caution you on how care full you have to be trying this procedure.

57" Toshiba with wavy green/red lines "good overall picture"


Appears to be a convergence problem, the chips are located on large aluminum heat sinks. Check near the 2 or 3, STK IC's for + and - voltage usually 20 to 25vdc. If 1 or both are missing, check microfuses. They should both be close to equal in voltage reading, if not, turn set off after it has been on for 10 minutes, feel the heat sinks at each IC,if one is hotter than the other, replace both IC's or all 3 if it has them. Now check the small low ohmage resisters in and around the STK IC's and you will most likely find a few burnt or discolored and have changed in value, replace these or the new chips installed will self destruct.

Toshiba 61h70 Picture Problems Hello, I have a Toshiba 61h70 TheaterView HD Projection TV, and was recently having some slight convergence issues (red was out of alignment and could not be adjusted). So I researched and found that the IC?s (STK392-110) needed to be replaced. I initially purchased them on eBay, to later find out that they were cheap clones and did not work (they made the convergence worse, actually). I then purchased 100% Sanyo IC?s from a reputable dealer and replaced the IC?s again. Once finished, I then entered the service menu and adjusted the convergence alignment. Once the alignment was perfect, I hooked back up the TV antenna, the DVD player (composite), and the S-video from my computer. The convergence is fine, but now I?m having a totally different issue ? the video is ?scrolling?. The menus will show up fine, however any incoming video inputs will show up okay for a split-second, but will then flash and the picture starts to scroll in different directions. This happens with any of the video inputs. I checked and changed all the service menu items to factory defaults, however this had no effect. I have pasted a link below to a short video that illustrates the issue that I?m having. Please note that the video starts off with a black screen, showing the ?input? menu, and then I selected the ?TV input? and changed the channels. You will see the picture fine for a moment when the channel is first changed, but then the picture will start to scroll. Any ideas of what would be causing this? And how can I correct the issue? I?m not a TV repair expert, so I?m not even sure where to start. Any help would be greatly appreciated. http://s75.photobucket.com/albums/i303/hybrydmike/?action=view₪t=TV_Troubles.flv
