Ok, I found out that cement and drilling machine fabricating techniques don't apply to tvs. The main board in this Sanyo is a N7EK and I found some traces buggered up on the back, but I thought I would be able to repair them. Following NorCal's video I discovered a blown I C for audio regulater. Ordered 2 chips per his part number and started into repair of my new flat tv. Got old blown out chip removed with just 1 slight problem, ground strap for terminal 4 pulled loose and I replaced it with a 2 strand wire. Ok now I went for the big Mcgilla, replacing the chip. However I don't have a hot air gun, just a small butane torch I had taken off of a teenage relative a few years ago. I will leave it to your imagination what he was using it for. So after the better half came running out of the backroom yelling whats on fire and my oxygen wasn't working too good and the smoke alarm went off, I determined I heavy handed with the torch.]

by cj_rehaHey all
I've been working on a 1984 Sanyo 27" color TV which had a smattering of bad caps in the video switching circuit. I found this oddball little 1uF 25V cap which looks to me like an early polymer, but I can't find concrete info proving it. I know Sanyo was a big player in early polymer cap development and this is the time period where they were just getting on the market, so I'm wondering if anyone has crusty old datasheets that could help identify it and determine if my suspicions are right? It has the same epoxy end seal and font/formatting as some old stock Os-Cons I've got laying...

by WidgetHopefully this falls under "weird devices".
I have a small torch, nothing special. I tried using it today, but it turned off after a few seconds. This happened a few times. Then the LED inside started to get dim and flicker, then it would go off, then it would come on bright, then off, then on dim and flicker etc... if you get my drift. The battery is a AA 1.5v which works fine.
Now, it won't come on, so thought I'd tear it down and have a tinker. I'm still a novice, so don't really know what I'm doing. I thought I'd try the LED to see if it works (which... -
by toddw65Hey All,
I have a Sanyo DP5834 that did have an issue with the backlights, but I disassembled the unit and repaired the LED strips by resoldering all of the connectors. Now I've reassembled it and I have backlights and sound, but a grayish screen. I can tap on the screen and see that it's on, but no picture. All voltages seem to be correct on the power board.
Based on the LCD Flat panel TV troubleshooting guide by Bud Martin, I'm thinking the T-Con has failed because I'm getting 12v both into and out of FP1 on the T-Con. Am I on the right track?
Thanks,...5 Photos -
by hugocarmoHi again guys.
Today I have a problem with this Sanyo VCR.
I bought it online, It worked sometimes.
I recap the Power supply and it started working fine.
Image is perfect and all digital effects too.
All of a sudden it stopped outputting sound. I checked for dried solders an all boards and soldered when needed, no fix.
I have no sound on playback, on tuner, or aux in.
On symptom I noticed is when it was working fine, the HI-FI led was on when I power up the VCR, now is OFF, A-B leds are on but when I put a tape they go off.
On one of the sound processing... -
