1 Answer

Switch works but no power

It was a hot day and running for a while. Could it be like i read b4 and the board has flexed over time and probably cracked the solider. Or is their any components that usually go. what are the power supplys like? If it is the power supply what are they worth. hope its the joints and ill run over them myself.

My TV works fine with excellent sound and picture quality but the picture comes and goes?


Check all cable connections, if known to be good, then I would think it is a internal board issue. these boards some times crack connection from heat cycling, boards flex hot and cold.

You could take the board out and look for a cracked solder joint on the board or a cold solder joint and repair.
Bad solder joints are very common in TVs and monitors due both to poor quality manufacturing as well as to deterioration of the solder bond after numerous thermal cycles and components running at high temperature. Without knowing anything about the circuitry, it is usually possible to cure these problems by locating all bad solder connections and cleaning and reseating internal connectors. The term 'cold solder joint' strictly refers to a solder connection that was either not heated enough during manufacturing, was cooled too quickly, or where part pins were moved before the solder had a chance to solidify. A similar situation can develop over time with thermal cycling where parts are not properly fastened and are essentially being held in by the solder alone. Both situations are most common with the pins of large components like transformers, power transistors and power resistors, and large connectors. The pins of the components have a large thermal mass and may not get hot enough during manufacturing. Also, they are relatively massive and may flex the connection due to vibration or thermal expansion and contraction.
To locate cold solder joints, use a strong light and magnifier and examine the pins of large components for hairline cracks in the solder around the pin. Gently wiggle the component if possible (with the power off). Any detectable movement at the joint indicates a problem. With the power on, gently prod the circuit board and suspect components with an insulated tool to see if the problem can be effected.
When in doubt, resolder any suspicious connections. Some monitors may use double sided circuit boards which do not have plated through holes. In these cases, solder both top and bottom to be sure that the connections are solid. Use a large enough soldering iron to assure that your solder connection is solid. Put a bit of new solder with flux on every connection you touch up even if there was plenty of solder there before.

No display blank screen


hi sir. the problem is the flex wire of the display on the handset unit and this is common. you have 2 solutions. first change for a new the handset unit. or open the handset, remove the main board, separate slowly the display screen from the main unit. whit a hot air gun, give some hot to the white flex on the main board side(not too much or you can destroy that). and tighten a little with your fingers on the flex and the main board. This should paste the flex.

sounds like it is incorrect flex plate
for bolts to keep coming loose i wouldsay the bolt threads in end of crank have been streched thru over tightening
you may be able to redrill and tap these
to do this you will have to pull engine
you alsocannot weld craCKS IN A FLEX PLATE
FLEX PLATES flex THEREFORE WELDING IS A WASTE OF TIME
WELDING WILL ALSO PUT FLEX PLATE OUT OF BALANCE WHICH AGIAN WILL CAUSE CRACKS AND PROBABLY WAS THE ORIGINAL PROBLEM TO START WITH

check flex part linking screen board to main board. most probably, it is a loose flex plug. it happens all the time otherwise, change screen board.
