Question about Mitsubishi VS-50805 50" Rear Projection Television

Mitsubishi VS-50805 Service Mode

Can anyone please help? I just got scammed by a repair man who said he was authorized by Mitsubishi but come to find out is not. The original problem was the unit would not show a picture. The green light next to the power button would come on but the screen was black. The repair man came out and showed me a capacitor had leaked and that he needed to wipe it up and it would cost $479.00 for 45 mins of cleaning. When I said no he got mad and said I owed him a $79 service fee and then put the TV back together. Before he finished putting the front speaker grate on he turned the unit on and the picture came on as normal. I asked if it was working and he said it might temporarily but he had to put it in service mode. Now when I turn on the TV it flashes different colors and then turns itself off after about 5 seconds. My question is how do I unlock whatever type of service mode this guy put the TV on? Thanks!

Sounds like you gotta call that guy back or report him for damaging your set.

I have audio but picture blacks out

You may have a bad ground on your vertical IC to begin with! Other repairs would include a bad ground on a coil or the horizontal transformer. The biggest problem is, Yes you have some bad grounds. Repair will be, to find the cracked rings underneath the boards and resolder. Take this note to your local TV Tech, this is your best defense in keeping the the repair cost down! Knowledge, in this case, is on your side now. Good Luck in your search!

Bad convergence IC possible - It's cheap if you do it your self, expensive if you take it to a repair shop. My Toshiba finally came on and stayed on after the IC's burned completely up and smoke poured out the back. Then mine stayed on with a distorted image. A good place for parts ->

Buzzing noise

It could be a high voltage transformer. The serial number won't help me locate the part, but there should be a part number on it. Anyways, this could be the transformer on it's way out. When they are on their way out, sometimes they will amplify the noise through the system and buzz through the speakers too. If you find a part number, check it out on to see what a replacement would cost.

You said you checked the convergence ICs and they're okay - WHAT did you check? Check temperature. Also, try rapping on the heat sink they're mounted on, see if that shuts it down or causes flickers in picture. If those provide no further insight, your problem is bad capacitors on the power supply/waveform generator/deflection board, you will need ESR equipment to check them and good soldering skills to replace. Unit will require in-shop service. A repair bill over $250 is a swindle - we did one for half of that last week.
