Question about JVC HD-52G786 52" Rear Projection HDTV
Hello i have a JVC model # HD56G786 DLP TV. The problem i have is that the set will not turn on. Whe i try to boot the set up it starts as normal as the blue power light stays on and the small red lamp/program led blinks slowly,but after a few seconds the blue power light goes out and the red lamp/program light begins to blink rapidly. I have checked the lamp and it is good. I have a feeling it is in the power supply board but there is no visible damage to any of the components on the board so I am not sure which component is bad if it is the power suppy board at all. all help on possible fixes for this would be great. not sure if this a common issue but if it is it hopefully will be an easy fix.
Hi and welcome to FixYa,
Sorry but there could be a number of possibilities and the best diagnosis would be to perform voltage checks of critical boards and compare with known readings. Common problems could be as simple as cold solder or loose connections, thermal fuse of the cooling fan or the light engine in some models not necessarily what you have.
This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings.Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.
Good luck and Thank you for using FixYa.
