Resposta para "Sharp 50" green light comes on, no pic or sound. then wont power off"Fixed some of these when they were still under warranty. The LED’s in your TV are not lighting. Manufacture would send a new panel (screen). Pull the main board and power supply from original TV and place into new panel. Regardless of what you might see (replacing the actual LED’s in the panel) on You Tube, this is not an easy repair. Consider a new TV. Thanks for asking, Matt of Martins TV Repair.
Resposta para "Why is my screen blank even though there was sound"Hmmm………. this is a LCD . Lcd would suggest an inverter board, or sometimes the power supply will include an inverter that will illuminate the screen. I would suggest you go to the power supply for a fix. Look for capacitor locations C201, C206, and C253. If these are bulged, replace these. Should be a simple fix. Find a electronic hobbyist to do this for you. Thank you for asking, Matt of Martin’s TV Repair.
Resposta para "The throttle will not return to full idle."If by now you have used this unit for two seasons, you will have to replace a muffler. Two cycle engines will produce more afterburn and will eventually clogged the muffler. Result, an engine that will not idle. In my case the fix was an easy one. I drilled a couple of holes in the muffler. It is not a warranted repair. But it did work for me. Thanks for asking. Matt of Martins TV Repair.
Resposta para "65uf6800 tv comes on has snowy picture on all inputs"I would suggest that the main board is your problem. As this unit is very warm during use and cools when shut down.The solder will expand and contract. This will produce poor grounds on all the HDMI connections, HDMI M1, HDMI 2, HDMI 3 and so on.One thing to try before you make a new board purchase try this. LVDS cables……….there should be two of these. Making for four connections. They are ribbon cables from power supply to main board. Carefully lift up the plastic connections, pull ribbon out and clean the connection with a clean pencil eraser. Ribbon and board connection, replace ribbon on each account. Thank you for asking, Matt of Martins TV Repair.
Resposta para "My jittery blurry picture problem"I have repaired many of these under warranty. Unfortunately the problem was corrected with a new panel. The panel is as much as the TV it self. It is not a feasible repair. It may surprise you, as most of these models have or will come to an end, as in your case. Wish I could tell you different. Thank you for asking, Matt of Martins TV Repair.
Resposta para "No AM on Marantz 2252"First of all…an older unit, this should be a simple fix. There are two coils one for AM one for FM. I have seen this problem many times. The first, is to turn the unit over. There should be a cover to remove, and expose all of the soldering area. Chances are you do not know where to find the coil (coils), may have three or five pins. Don’t worry about this for now. Have a hobbiest solder any and all broken grounds. A broken ground is when you see cracked rings around any pins or tiny posts protruding from the electronic board. Solder all power transistors, heat sinks and large ICs. This is called shot gunning. You will undoubtedly resolder the coil. Chances are good AM will return. One must note as well…..if your fuse or fuses are good in this unit, chances of fixing are very good! Thanks for asking, Matt of Martins TV Repair.
Resposta para "65uf6800 tv comes on has snowy picture on all inputs"Bad grounds on any video cable will cause this. You may have a problem with the cable / satellite box. You may have video connections crossed. Just trouble shooting. Check cables……I do believe that is a good place to start. Matt of Martins TV Repair.
Resposta para "LG 65LB730 Screen problems, pulsating"You are experiencing a TV with an LED problem. Very common. I have repaired these under warranty. Your TV panel is the culprit. You may try to replace the LEDs. This is extremely difficult and can result in a complete waste of time. Recycle and shop for new. Thanks for asking, Matt of Martins TV Repair.
Resposta para "Sony Bravia 40". KDL40W650D. NO POWER, RED light flashes 3"3 blinks…..Panel will not illuminate. You have LEDs that will not come on. To replace these is almost a complete waste of time. The actual repair is to replace the panel..To costly to repair. Recycle and shop new. Thanks for asking, Matt of Martins TV Repair.:
Resposta para "Why won't club car will not accelerate to high speed?"I would have to believe that your breather is dirty. Find the breather and look for an air sensor. If there is one, its generally simple to pull it off. Go to any car part store and purchase a mass air sensor spray. Follow directions on can. You may be surprised how easy it is to fix this. Thanks for asking, Matt of Martins TV Repair.
