    Same problem - sound but no picture. Gradually took longer and longer for picture to appear. Until finally, the picture wont generate at all.

Take back off lie flat

where the hd leads go into that board remove the screws at the top and bottom as its one long unit top to bottom
unscrew metal shield as well

remove all cables from board 2 ribbons are locked and require clipping down then ribbon removes
flip board over remove metal can to expose board notice 2 TSOP chips at top look att the pins one should look dull and not shiny

to fix i used heatgun a quick blast on pins sorted problem out

mask off board and chip around with metal etc... to not damage board.

Disassembled my unit today. On the suggested digital board, there are a lot of surface mounted chips. The 29LV400 flash memory chip looked bad soldered under the magnifying glass. Resoldered the chip and voila the unit is working like new.

Plasma tv green light flashes 5-6 times then stays green but no picture or sound


Remove one at a time the Y sus and Y buffer cables that go to the power board and see if the set stays on then, you may have a distorted pic, replace the board that makes the set stay on...there are some transistors on the buffer board that give issues a lot and I'd guess that's where your issue is at

I have a sony tv model kdf-50e2000,and it has a problem with the picture going blank,the only light that on or flashes is the green (POWER) light. when turning the set on the green light blinks as it...


You tv used lamp XL-2400 or also known as F93087500. It is very common for this bulb to fail and have the exact symptom you are experiencing. I cant count how many times I have seen it.. Replace the lamp with either the exact Sony or an OEM and you will be back in business..
Good Luck!!

I recently bought a JVC KD-R311 car stereo, its a great stereo but my settings dont save, for instance i set the perfect sound adjusting bass/treb/mid/loudness and whenever i turn my car back on after...


You need to have the yellow wire from the stereo connected to constant battery/12 volts. That wire supplies power for the memory, if it is connected to ignition power, when you turn off the car, the power for the memory is off also.

My TV pictures turns black afetr a few hours but I still can hear sound perfectly!!!


It sounds like your rptv lamp is going out. If this is an older DLP this is most likely the cause. You can get a replacement at www.laptopsforless.com part number BP96-00224J for $151. If the tv is still under warranty, I would have them do it, otherwise replace it yourself. If so here is a link to give you step by step instruction. Please give me a good rating. ;-)

One thing you should not do with electronic devices which have a start up proceedure is to turn the power off, and then on again without a wait of about five minutes. Some equipment manuals warn you about this, and specify a longer period. The start-up has to have time to reset. It will be more likely to reset if you do not leave it on standby, and even unplug it. In your TVs case you need to describe the distorted picture as it may give a clue to a fault, or incorrect start-up. The horizontal line indicates the frame timebase had stopped working. No picture could be a fuse blown inside the set, or a timed cutout which may reset after a time. Try after several hours to see if it comes on. If it is just the frame timebase (vertical) it is worth repairing.

probably some cold solder joints. take your time and check over whole circuit board and re-solder what looks bad.
