The module was once allreaday replaced. I'm not shure if the present board is really genuine.
Not enough information on the problem for me to answer. I would say you need to have it checked by a professional instead of blowing power supplies.

You should contact Roland to find out who their parts dealer is for your area. Once you are on their site, click on the Support tab.

Checking the specifications of your car, you can replace it with any battery that is the "approved sealed type". Make sure the cold crank amps match or is better than you have already. When you go to the battery shop (Sears, many car parts stores, etc), tell them your model of car and year, and they will be able to match it to what you have.
Also, make sure that you have one of your doors open when changing it to prevent being locked out.
Some other stuff of note:
When replacing the battery on 4.0/4.6 and later model Range Rovers, you should leave one of the doors open (preferably the drivers door) to prevent being locked out. This should prevent the locking system from automatically locking the vehicle and arming the alarm when the battery is being disconnected. Then, disconnect the battery negative lead first, and complete the replacement procedure normally. Afterwards, you need to put the key in the ignition to reset the alarm system and ignition transponder. You also need to key in the radio code to get it working again, and resynch the windows and sunroof. This procedure is described in the owners handbook. On the Mk III Range Rover, you even ave to reset the steering sensor after reconnecting the battery.

The colors weren't lining up correctly on my HC-P4752W which is only about 30 months old. I did a little bit of research and got ahold of the people at http://servicemanuals.vstore.ca/ They recommended replacing the IC's as well as the IC resistors. I purchased the replacement parts from their site and made the repairs myself. I should mention that I didn't have any previous soldering experience. The repair was easy and a complete success. You may find replacement parts elsewhere for slightly cheaper but what you won't find is the prompt and detailed customer service that they provide. They gave me there # and said to call if I had any questions before or during repair. I took advantage of their services and got answers every time I called.

Good Day, petterk;
Try resetting TV by unplugging from the A/C outlet for3 to5 minutes. This a 1994 Model, you can't new boards from Mit's. Try this:
1). CHECK FOR 1200 VDC AT PIN 1 OF CONNECTOR "DK". IF LOW OR MISSING CHECK R5D9 100 OHM 1/2 OFF PIN 1 OF THE FLYBACK ON THE MAIN PCB. 2). CHECK IC401 PIN 8 FOR 28 VDC IF MISSING CHECK R510 1.2 OHM 1/2 W OFF PIN 5 OF THE FLYBACK. IF OPEN IC401 PART # 272P239050 MAY BE SHORTED. BOTH ARE ON THE MAIN PCB. 3). CHECK FOR SHORTED OR LEAKY Q2H0, IF BAD APPLY FOLLOWING CIRCUIT CHANGE TO CORRECT. ON FOIL SIDE OF PCB-SIGNAL, SOLDER A 1S2471 DIODE CATHODE TO BASE OF Q2H0 AND ANODE TO EMITTER. LOCATED ON PCB-SIGNAL AT IC201 PIN 2. PT # 264P045040 AND REPLACE Q2H0 PART # 260P559030. 4). CHECK C2H1 100 UFD 35 V C2H2 1 UFD 50 V AND C2H3 47 UFD 35 V OFF OF Q2H1 IN THE SPOT KILLER CIRCUIT ON THE SIGNAL PCB.
Good Luck, big IRISH. PS: or call for service, Cost average repair about $500.00, you do the math maybe it's time for a new TV. G.L.
