Question about Mitsubishi WS-55807 TV

1 Answer

WS55807 Hi, I am having the same exact problem with my Mitsibishi WS55807 and was wondering if you ever fixed the issue and if so what was the problem. I am reluctant to spend hundreds of dollars to fix this since the set is almost 8 years old, thanks....

Good Day;

Yes, there is a TRICK of removal of centerboard. Remove back cover, after disconnecting the POWER CORD, remove 2/3 screws from black chassis frame, on back bottom, release wire restraints, look for two clips on front of black chassis. Can see easier if you remove speaker grill and small panel. Remove all golden type screws from PCB. Replace IC’s STK392-570 (2).

More than likely your TV has "COOLANT" (ethylene glycol) on the circuit boards. This fluid comes from the CRT's (picture tube) this fluid is used to keep the CRT's cool, such the name. This fluid from the CRT's leak when TV is on for long periods of time, the chamber expands and the seals leak.

One can remove this fluid by using "acetone" & small brush. The fluid is hard to see, use bright light, they spots can be smaller then a DIME. Also, the fluid can corrode the parts and traces on the boards. To protect the TV in future place heavy plastic or thick cardboard over affective area, make sure TV has proper air flow around TV.

If after the fluid has been removed and TV still does not work, call an Authorized Service Center to come out and repair TV after giving you an Written Estimate. The boards are not available.

Always try resetting the TV by unplugging it for one minute then plug back into A/C outlet and ALWAYS UNPLUG TV BEFORE ATTEMPTING ANY REPAIR ON THE TV.

Good Luck, big IRISH.

How do I enter the service menu on an Emerson EWF2004 CRT Television? (Pictures of the OVERSCAN ISSUE will be provided if needed.)

Older sets had vertical and horizontal size controls. If you have the horizontal size control, turning it counterclockwise will reduce the size of the picture horizontally and reduce the overscan.

This is a convergence rpoblem that is either bad connections on the pins of the convergence ICs or defective ICs. If you can solder and are comfortable working inside TVs where there are potentially dangerous high voltages, let me know and I'll provide additional details and instructions for fixing this yourself.

Same problem

tv repairman came to house with a wrapped cable demagnetizer, plugged it into the electrical outlet, waved it around in front of the tv screen, and the color returned to normal. Sounds magical, but that's exactly what happened to correct the color, and it has remained perfect since then

I had this problem and corrected it by resoldering all 36 pins of the 2 convergence IC's. Biggest problem was getting the circuit board out far enough to prop it up and get underneath and get at the solder connections, required unplugging a few cables, 3 screws holding it in. Works great now, I used to fix it by taking the back off and banging on the Heat Sinks which house the IC's, I could tell then that it reacted like cold solder joints. I decided after a field service guy charged us 95.00 for a service call and quoted 650.00 for a repair. Hope this helps someone.

Problem with t.v.

What is the exact model # of the set and i can assist you more. Is it a WS55807? Let me know and we can continue after that.
You definately need a HDTV Box from cable or i recommend the Dish Network for the $$. You can run 2 TV'S independantly off one receiver and watch 2 different things at once or record 2 things at the same time. They work great. But cable has its advantages also like ON DEMAND. It a good feature also. Let me know if this helps out. Thanks Jay

Mitsubishi WS-55807 "Bow-Tie" Problem

If your not a tech, its highly advisable to not even open the set because of the high voltage and x-ray radiation issues. Now if your a technician ,you gonna need to get a service manual, Look up the convergence circuit, Find the two or three convergence driver ics, find the b+ feed resistors to those ic, and order the exact replacement parts. if you dont replace all at once, and with exact replacements, you will be in the same boat a few months down the road. This is not a repair a handi-person should consider doing as even if you get the ics replaced, your gonna need to do some minor or could be major convergence alighnment and your gonna need a cross hatch generator to do this. This repair should cost ya about 300 to 400 bucks? Sorry man Good Luck
