Mitsubishi TV CS2044
Customer Complaint: Remote does not work.
The remote checked ok but the TV wouldn't respond to it. When the channel scan button was pushed the set would scan the channels but wouldn't stop on any channel. I found an open circuit trace under diode D7?? (couldn't read number due to glue on circuit board). The trace runs between R792 and R701. I installed a jumper wire to replace the trace and that repaired the TV.

Mitsubishi TV CS-20SX1
Customer Complaint: TV only has a thin line across the center of the screen.
The TV had intermittent vertical deflection. IC401 had poor solder connections on the pins.

Mitsubishi TV CS-2610R
Customer complaint: Lines at the top of the picture.
There were line at the top of the picture and would expand and contract vertically R521 a 1.2 ohm 1/4w resistor was open.

Mitsubishi TV CS-2610R
Customer complaint: Only snow no picture.
The 12v on pin 16 of band switch IC771 was missing. R515 3.3 ohm 1/4w resistor was open.

Mitsubishi TV CS-2610R
Customer complaint: No color

The signal control IC201 had only 4v on pin 11 instead of 9v. 9v regulator IC501 was shorted. IC501 P/N {266P923020}, {NJM78L09}, or {ECG1902}


Mitsubishi TV CS-2610R
Customer Complaint: Black screen, sound ok

R608 a 100K 1/2w resistor was open. This resistor is located on the CRT PCB.


Mitsubishi TV CS-2610R
Customer Complaint: Picture is too bright and has lines in it.
The screen was too bright and had retrace lines in it. I checked the crt cathode voltages and they were missing. There was no 200v to the crt board. D552 the 200v rectifier was shorted and R560 the fuse resistor was open. Replacing them repaired the TV. (D552 p/n 264P295020 or ECG552) (R560 1.2 ohm 1/4w)

Mitsubishi TV CS-2657R
Customer Complaint: No picture sound ok
The TV had no video on tuner or external. Video switcher IC2A0 was shorted. (IC2A0 LA7952)

Mitsubishi CS-26EX1
Customer Complaint: Black screen sometimes with a flash of color in it and the sound is ok.
C7001 a 4.7uf 35V smd electrolytic capacitor is leaky. C7001 is located on the PIP board.

Mitsubishi CS-26EX1
Customer Complaint: Picture rolls and fades in and out.
C7036 a 4.7uf 35V smd electrolytic capacitor is leaky. C7036 is located on the PIP board.

Mitsubishi CS-26EX1
Customer Complaint: PIP rolls
The PIP child picture was rolling from the top to the bottom and also from one side to the other. It would not sync with the main picture. C7031 a .22uf 50V smd electrolytic capacitor was leaky. C7031 is located on the PIP board.

Mitsubishi CS-26EX1
Customer Complaint: PIP has no color
The PIP child picture was in black and white and would get some very faint color after playing for an hour. C7020 a 2.2uf 50V smd electrolytic capacitor was leaky. C7020 is located in the PIP board.

Mitsubishi TV CK-3136R
Customer Complaint: Dead; just clicks
The TV had standby power but no power to the horizontal stages. The 130V power circuit was dead. IC901, STR-S5141G was open and after replacing it the 130V line was 175V. Capacitors C914, C916, and C956 were all defective. I replaced the capacitors, but I still didnt have high voltage even with the 130V line at the correct value. I found that Q532, the horizontal output transistor, was shorted. I replaced Q532 and a 3.15A micro fuse and the TV ran ok.

(IC901 P/N 272P255010 or STR-S5141G)
(Q532 P/N 260P608010 or 2SD1879)
(C914 470uf @ 50V)
(C916 10uf @ 100V)
(C956 2.2uf @ 200V)

Mitsubishi CK-3531
Customer Complaint: Dead set
The TV had high voltage, but the screen was black and there was no sound. R8A2 was open. This resistor goes to the input of 12V regulator IC8A2. (R8A2 1.5 ohm 3W)

Mitsubishi CK-3531
Customer Complaint: White lines at the top of the picture.
C928 in the power supply is leaky. (C928 1000uf 50V)

Mitsubishi CK-3531
Customer Complaint: Black at the top of the picture.
The vertical was folded over at the top and after a few minutes would fill out the screen. IC4E1, the vertical output IC, is bad. (IC4E1 LA7838)
