by ronaldopdiasHi all,
Since about a month or two ago, we've observed a new type of 'serialisation' on the LCDs and we're just curious whether anyone has seen this- New LCDs straight from the factory (not programmed)- if the Mac is restarted or switched on from a cold boot, you must close the lid, then open it again (so two cycles of opening and closing the screen) in order to get display.
- Transplant the IC onto another screen:
- If the model and revision match exactly then it will perform as normal
- If the manufacturer matches exactly BUT its a different revision, the colours are mostly in

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 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 GKdaysI have a damaged capacitor from a bootleg double dragon arcade pcb and I have the normal values from it:
10 volt, 100uF, 85c, but someone from an arcade forum said that the ripple current is not that critical and any good quality low esr cap would be fine, the damaged one is an electrolytic can type but I don't know what to look for as far as low esr is concerned, can a ceramic capacitor be used instead, the capacitor is going to the +5 volt
I don't know the brand but on the top of the capacitor is stamped "76 F6" if there is a datasheet ide be able to...-

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... - Loading...
