Have a mitshibish tv model wd65638 we replaced the bulb it blew. Replaced the bulb again it comes on color changes around but picture is ok then tv shuts off and red light comes on.


You have wasted too much money already. By now you could have replaced it with a new TV. Forget fixing this one and get an LCD or LED Flat screen TV. Projection sucks.

Blinking green timer light on front nearpower button keeps blinking, tv will not turn on, unplugged for 24 hours and tried again, also hit system reset and still nothing.


Thats a common problem when the caps on the DM need replacement. They will function fine untill power is interupted then the set will not complete the boot sequence when power is reapplied and the led will just continue to blink. Hers a link to the kit that will usually repair that issue the kit comes with instructions.

My W3201C 32" LCD TV made a loud popping noise when I turned it off. Now it will not turn on. No power. No LED light.


That would be your transformer popping and dieing. Usually the popping is followed by a burning smell which is a good indicator that the part is unrecoverable. The cost of the part is variable based on the make and model TV and is usually not too labor intensive to replace. If not under warranty, let the repair gut know that you know what the problem is. Then, ask them to quote the cost of the replacement part and part number. Then ask them to quote you their hourly rate and get a time estimate. Then, google the part number and see if the cost is reasonable.

If your LCD is less then a year old, I would suggest to contact the manufacturers to have it fix under warranty.
The failure on your LCD could be a defective back light inverter or a power supply not providing enough power to the back light inverter board.
Let me know if you require further assistance.

Won't power up



If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address. 

Here are the symptoms...

Primary Symptom: No Audio or Video. Power light will come on briefly then shut off.
Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.

Hope this helps,
