Question about Sanyo DS27910 27" TV

1 Answer

Focus good in centre but fuzzy around edges

Hi - just picked up this TV cheap out of the paper, so probably not worth wasting a tech's bench time, but maybe I can tweak something myself (limited electronics experience). Focus is sharp in the centre of the screen but fuzzy around the sides. Colors look okay, tube is probably starting to get a bit worn. I'm going to guess it's whatever circuitry compensates for having a flat surface screen rather than a rounded one?... Thanks in advance, GENE

If you have some electronics experience, is it with TV'S?? There is way to much Hi Voltage inside these sets to be tweeking around as this set will have to be plugged in and running when you do the a grey scale alighnment and color drive alighnment. If the pic is out of focus on the outside its probably like you said not wrth a techs time unless you wanna pay a min. bench charge to clean the grids inside the CRT with a speacial piece of test equipment. As a handy man its not a good idea to service these sets as there are no user serviceable parts inside+. Good Luck

Envelopes jam, worked fine when I bought it 6mths ago

Hi Jerry
the paper tray has a triangular upright paper guide at the back edge (roughly in the centre) to keep the paper from sliding out the back of the tray. It has a serrated edge on the paper side. Try covering the edge with some masking (or similar) tape to make it smoother. Not sure about envelopes, but this has stopped copy paper jams, so worth a try. If it doesn't work for you...easy enough to remove the tape.
good luck!

I had a samsung hitb system but the dvdplayer/receiver died and i dont want to waste the speakers. Is there any way i can cut off the special samsung ends and convert these speakers for use on my laptop??...

Yes you can definitely do that. However, the cost might not be worth it for you assuming you don’t already have a pre amp or a receiver laying around somewhere. What you could do, though, is cut off the ends of the Samsung speakers and connect them to speaker outputs on any old audio video receiver. Then, audio out of your laptop to the input of the receiver. I would ask around with your friends if they have an old one laying around. Also, used electronic stores will have them for cheap. Like I said earlier, it’s possible but may not be worth the cost as you could get a full speaker system for your laptop pretty cheap these days! Good luck!

How to fix fuzzy pic & red,blue,green lines on your screen?

Typically this is due to a convergence chip failure. This repair can be done pretty easy with the proper instruction. Have a look at this video to help determine if you truly have a convergence problem.

You need a new convergence board. Not an easy fix, sorry.

Colour misalignment and focus

Inside of the tube assembly, there is a cooling liquid. This could be a job to change, and then re-adjust everything. It is also possible that on top of this, there are problems with the convergence and bias control circuits.

Typical repairs can run in the area of about $400 to about $800 depending on the amount of work and type of parts required.

Personaly, I would go out and get a good Plasma or LCD TV at this point!

Your ICs are bad that control the Convergence. I would quess that the ICs that they have used before have been the cheaper versions. Sanyo are the best the cheap ones only last for a while then need replacing. The sanyo chips cost considerably more than the imitation ones but are worth it in the long run.

36" tube tv. picture fuzzy and out of focus

It sounds like you may have a G1 intermittent short in the picture tube, which unless it is still in warranty would not be worth repairing.
