Question about Sharp 32F640 32" TV

1 Answer

Sharp 32F640 32" TV works intermittently

I have a Sharp 32F640 32" TV that works beautifully when it works. Sometimes when turning it on, it attempts to turn on but will not. We can unplug it for a period of time and try turning it on again. Sometimes it will then turn on and sometimes it will not. We live at the beach. Could the moisture or salt in the air be causing this? If so, what can I do to fix it and stop it from occurring?

The easiest thing to check is for loose conections because the unit is intermitant,the chassis should be check out for overheated areas and cracked solder joints in the power supply,horizontal driver and all the diodes and resistor off the secondary of the output trnasformer(flyback),if you are familiar with tv service this will help but if you are not too familiar be safe and call for assistance form a servicer.No doubt humidity can damage anything with time.

Turn the power off to the television and everything connected to it. Count to 10 and just plug the television in. See if it works OK? If it does, start turning on each item connected one by one. If it comes back just on the television, I would contact Sharp.

Your Caps on the PSB- Power supply board are on their way out. Pretty soon it won't turn on at all. You will only get the Fault code blinking LED at startup. Recap the UF capacitors on the PSB. Works 90% of the time.

I ve got a sharp aqueos tv i turned oevr channels


Try this: unplug the power cord from the wall, let TV set stand for AT LEAST 30 minutes, then plug back in and and see if the TV operates as normal.
Sometimes this works and sometimes it doesn't.
Good luck !

Sharp Aquos not always starting up immediately when powering on??


I had the same exact thing happen. I think it's related to a failed firmware update attempt after reading a post on the AVS forum of a guy who also had this problem on this TV. What I did is plug back in the USB drive with the firmware update on it that I had used earlier, and the TV started right up.

No sound on Sharp Aquos 37' LC-37D4U


Almost all intermittent audio or audio failure problems with Sharp Aquos LC**D4U, LC**D5U, LC**D6U, and LC**D7U televisions are the result of a relatively simple design flaw involving the heatsink pad compound used on the Tripath TA-2024 amplifier chip (IC2502) found on the A/V board. This compound has a fairly low melting point and, over time, tends to seep out from between both top and bottom heatsinks onto the legs of this chip as well as onto circuitry immediately surrounding it. Further, over time the seeping compound also becomes somewhat conductive creating bridges which short the audio amplifier circuit causing everything from intermittent audio to complete audio failure.

Fortunately, in almost every case audio can be completely restored by cleaning the old compound from both top/bottom heatsinks and from both sides of the PC board in the area immediately surrounding the chip (I used rubbing alcohol which worked quite well). Sharp has issued a service bulletin addressing this issue (LCDTV-194) wherein a ‘2502 Heat Kit’ is specified. This kit is Sharp Part Number: PSPKIT663WJZZ and is available from circuitcity.partsearch.com for $19.95. However, it’s entirely possible to get by with the heat pad only, Sharp Part Number: PSPAZA663WJKZ for only $9.95. Please note that board replacement for this problem is almost never necessary, so if you’re working with a repair technician be sure and insist that he/she be certain to try cleaning the old board and replacing the aforementioned heatsink pads before charging you for a new board.

If one is reasonably familiar with electronics disassembly/reassembly and is willing to take their time, this can even be a DIY project. It is possible to find ‘important service references’ by simply entering LC26D4U (the 5, 6, and 7 series are very similar, and this information covers all screen sizes) into the search field at eserviceinfo.com. This will greatly aid in disassembly/reassembly of the TV, as the A/V board is somewhat ‘buried’ under other boards. Please refer to post # 373 at avsforum.com/avs-vb/showthread.php?t=647174&page=13 for pics of the information detailed here.

Particular thanks are owed ‘Aureius’ of the AVS forums for his research efforts concerning this issue !
